Abstract:
The article contains research on avifauna compliment, numeral and bird distribution which depend on differentiation of habitat and seasons in Hohhot for last year. A bird is one of the important species of vertebrates which has an essential role on ecological balance and biological control. Having diversity of birds is the main composition of biological diversity. Bird community structure is determined by relationship of bird’s species and general correlation of birds and environment. Diversity of bird community structure has direct correlation of its species, bird community numeral and habitat. Also it depends on geographical factor, habitat, diversity of plant community, plant vertical structure, food resource, possibility of shelter and other factors. Therefore, bird species become a very valuable indicator for ecological condition of the city and environmental ecological quality. We have divided the areas around Hohhot, Inner Mongolia into 6 different habitats such as grassland, farmland, residential area, woodland, wetland and garbage dump. We have performed the bird fundamental study, and investigated bird flora, ecology, distribution, diversity, environment, and community structure in different habitats and seasons.

Abstract:
Abstract Wild birds play important roles in the maintenance and dispersal of tick populations and tick-borne pathogens, yet in field studies of tick-borne disease ecology and epidemiology there is limited standardization of how birds are searched for ticks. We conducted a qualitative literature review of 100 field studies where birds were searched for ticks to characterize which parts of a bird’s anatomy are typically sampled. To increase understanding of potential biases associated with different sampling approaches, we described variation in tick loads among bird body parts using field-collected data from 459 wild-caught birds that were searched across the entire body. The literature review illustrated a lack of clarity and consistency in tick-searching protocols: 57% of studies did not explicitly report whether entire birds or only particular body parts were searched, 34% reported concentrating searches on certain body parts (most frequently the head only), and only 9% explicitly reported searching the entire bird. Based on field-collected data, only 22% of ticks were found on the head, indicating that studies focusing on the head likely miss a large proportion of ticks. We provide tentative evidence that feeding locations may vary among tick species; 89% of Amblyomma americanum, 73% of Ambloyomma maculatum, and 56% of Haemaphysalis leporispalustris were on body parts other than the head. Our findings indicate a need for clear reporting and increased standardization of tick searching methodologies, including sampling the entire bird body, to provide an unbiased understanding of the role of birds in the maintenance and emergence of tick-borne pathogens.

Abstract:
Landfills have the advantage of meeting the energy needs of the birds quickly. They offer easy access to food and widely available throughout the year. In this study, birds were counted using observation points on an open landfill in the restored of Souk-Ahras region (north-eastern Algeria) for one year from July 2013 to April 2014. Seventeen species (17) bird species belonging to eleven (11) families were found: Ciconidae, Corvidae, Accipitridae, Passeridae, Hirundinidae, Motacillidae, Columbidae, Ardeidae, Sturnidae, Laridae, and Pelecanidae, among them sedentary species, migratory, the visitors, and invasive species, which are exploiting the discharge for feeding or rest. Species richness and abundance in landfill site were found to be higher than that of naturel habitat around the site. Their abundance varied according to the seasons.landfill site support both common bird species as: Columba palumbus, Columba livia, Streptopelia decaoto, Ciconia ciconia, Corvus corax. In addition to that, rare bird species such as Pelecanus crispus. Ecology and dynamic of each species, during an annual cycle of bird’s populations allow us observing all the interactions and reactions between the individuals and the different populations of birds. Souk Ahras landfill is a resting place and a source of food for birds, which means that it needs a censuses urgency update of migratory birds which frequent our region as well as monitor their state of health. It is also interesting to follow the process of colonization in urban Souk Ahras city.

Abstract:
Unsustainable commercial exploitation poses a serious threat to many of Vietnam’s native bird species. Here we report on a survey of the country’s online bird trade, conducted across four major online platforms. Between 9 March and 3 April 2020, a total of 434 posts were recorded, accounting for 834 individuals of at least 50 species, ten of which have not been recorded in Vietnamese trade before. Ninety-two percent of the recorded species were native to Vietnam and 18% (n=9) of the species, accounting for 15% (n=115) of the recorded individuals, are protected under Vietnamese law. Recorded prices ranged between VND16,667 (~US$0.7) and VND7 million (~US$303), depending on the species and on a bird’s specific singing qualities. The highest trade numbers were found on Chợ Tốt (186 posts, 335 birds), followed by Facebook (161 posts, 325 birds), Chợ Vinh (82 posts, 169 birds) and Chim Cảnh Đất Việt (5 posts, 5 birds). The scale of the observed trade appears to confirm a partial shift towards online platforms in Vietnam’s bird trade, or at least an increase in the use of online platforms to trade wild birds. In anticipation of a further development of this trend, we urge the Government of Vietnam to improve regulations and to take greater enforcement action against illegal online trading practices.

Abstract:
The recently extinct Malagasy elephant birds (Palaeognathae, Aepyornithiformes) included the largest birds that ever lived. Elephant bird neuroanatomy is understudied but can shed light on the lifestyle of these enigmatic birds. Palaeoneurological studies can provide clues to the ecologies and behaviours of extinct birds because avian brain shape is correlated with neurological function. We digitally reconstruct endocasts of two elephant bird species, Aepyornis maximus and A. hildebrandti , and compare them with representatives of all major extant and recently extinct palaeognath lineages. Among palaeognaths, we find large olfactory bulbs in taxa generally occupying forested environments where visual cues used in foraging are likely to be limited. We detected variation in olfactory bulb size among elephant bird species, possibly indicating interspecific variation in habitat. Elephant birds exhibited extremely reduced optic lobes, a condition also observed in the nocturnal kiwi. Kiwi, the sister taxon of elephant birds, have effectively replaced their visual systems with hyperdeveloped olfactory, somatosensory and auditory systems useful for foraging. We interpret these results as evidence for nocturnality among elephant birds. Vision was likely deemphasized in the ancestor of elephant birds and kiwi. These results show a previously unreported trend towards decreased visual capacity apparently exclusive to flightless, nocturnal taxa endemic to predator-depauperate islands.

Abstract:
ABSTRACT Wild birds interconnect all parts of the globe through annual cycles of migration with little respect for country or continental borders. Although wild birds are reservoir hosts for a high diversity of gamma- and deltacoronaviruses, we have little understanding of the ecology or evolution of any of these viruses. In this review, we use genome sequence and ecological data to disentangle the evolution of coronaviruses in wild birds. Specifically, we explore host range at the levels of viral genus and species, and reveal the multi-host nature of many viral species, albeit with biases to certain types of avian host. We conclude that it is currently challenging to infer viral ecology due to major sampling and technical limitations, and suggest that improved assay performance across the breadth of gamma- and deltacoronaviruses, assay standardization, as well as better sequencing approaches, will improve both the repeatability and interpretation of results. Finally, we discuss cross-species virus transmission across both the wild bird – poultry interface as well as from birds to mammals. Clarifying the ecology and diversity in the wild bird reservoir has important ramifications for our ability to respond to the likely future emergence of coronaviruses in socioeconomically important animal species or human populations.

Abstract:
The parasites of generaHaemoproteus, Plasmodium,andLeucocytozoonare well-known avian haematozoa and can cause declined productivity and high mortality in wild birds. The objective of the study was to record the prevalence of haematozoan parasites in a wide range of wetland birds in Bangladesh. Six species ofHaemoproteus, seven species ofPlasmodium, one unidentified species ofLeucocytozoon, and one unidentified microfilaria of the genusParonchocercawere found. Data on the morphology, size, hosts, prevalence, and infection intensity of the parasites are provided. The overall prevalence among the birds was 29.5% (95 out of 322 birds). Of those, 13.2% (42 of 319) of birds were infected withHaemoproteusspp., 15.1% withPlasmodiumspp. (48 of 319) and 0.6% withLeucocytozoonspp. (2 of 319). Two birds were positive for bothHaemoproteussp. andPlasmodiumsp. A single resident bird,Ardeola grayii, was found positive for an unidentified microfilaria. Prevalence of infection varied significantly among different bird families. Wild birds of Bangladesh carry several types of haematozoan parasites. Further investigation with a larger sample size is necessary to estimate more accurately the prevalence of haematozoan parasites among wild birds as well as domestic ducks for better understanding of the disease ecology.

Abstract:
In frugivory networks, birds offer plants the advantage of dispersing their seeds away from the parent plants in exchange for macronutrients, primarily sugars, and water. The benefits for birds are clear, as they obtain food and water from fruits, and highly variable for plants, as birds may act in ways that vary from effective dispersers to seed predators. We studied two common species that interact frequently in the frugivory network of a Neotropical, periurban park: The clay-colored thrush ( Turdus grayi) and a nightshade ( Witheringia stramoniifolia), in order to evaluate the advantage of passing its seeds through a bird’s gut. We set up an investigation using captive thrushes that we fed with fruits of W. stramoniifolia. We had four experimental treatments: in two of them, seeds that had passed through the digestive tract of thrushes were germinated under greenhouse and controlled conditions; in the remaining two treatments, we germinated seeds that were not consumed by thrushes and were likewise germinated under greenhouse and controlled conditions. W. stramoniifolia seeds consumed by birds had a germination onset that was 1 to 2 weeks earlier than nonconsumed seeds. Mean germination rate and final germinability, however, did not differ significantly among treatments. In our study, passage through a bird’s gut accelerates the germination onset of seeds, an advantage that possibly enhances seedling establishment, but is not indispensable, for the dispersal of W. stramoniifolia. This bird–plant relationship ultimately accounts to a true mutualism.

Abstract The article presents the results of the analysis of changes in the fauna, population and ecology of the dominant and background bird species of the Voronezh upland oak forest, depending on the level of the recreational load. The object of research is the Voronezh upland oak grove, a unique natural landscape complex located within the city of Voronezh in the Central Federal District. The research period is 2014-2018. The census was carried out according to the standard method of counting birds according to the spring mating song with a fixed width of the counting strip equal to 50 m. The length of each route was 10,000 m. The results of the study showed that on the territory of the Voronezh upland oak forest, background and dominant bird species are represented by 38 species belonging to 5 orders … Most of the species belong to the order Passeriformes. In areas with a high degree of recreation, the number of synanthropic species and birds with a mixed type of diet increases. The consequences of the recreational impact are reflected in the number and species composition of birds.

Abstract:
Abstract The avian habitats in Eastern Europe are poorly managed in last decades. It is of highly noteworthy influence importance to obtain more information regarding the link between birds’ presence and environmental features in wetlands to improve this poorly managed system. In our study we investigated the effects of the various habitat, landscape fragmentation and weather variables on the bird assemblages in Eastern Romania, described by diversity, species richness and abundance of non-passerine birds in wetlands. Poisson regression modelling revealed wetland area, wetland heterogeneity, proportion of open-water, density of patches and habitats, landscape shape and temperature conditions have a noteworthy influence on the bird assemblages (p<0,05). Our results suggest that the link between environmental features and birds’ assemblage, in our study areas could be dependent on the presence of the emergent vegetation (shelter / reproduction zones), the balance between open-water area (feeding / nesting zones) and also other variables, as the temperature, the presence of the human living facilities and/or intensive fish nurseries in the neighboring zones. Waterbird distribution and abundance in eastern part of Romania are driven by similar factors to other part of the world and this study could be one of the first published on the topic in a region where It is a lack of information on waterbirds ecology. Such studies would bring valuable information about the ecologic factors influencing the lives of the birds, in the areas that were not stueid before, resulting in better conservation efforts and wetland protection, in estern part of Europe.

Abstract:
Reproductive success and survival of birds often are impractical to measure. Therefore, biologists frequently rely on measures of bird abundance alone to evaluate habitat quality for breeding birds. I examined whether results from standard survey techniques for birds during the breeding season reflected number of nesting pairs and reproductive success of 5 passerine species. Abundance of 3 species was positively associated with number of nesting pairs, but the relationship between abundance and reproductive success varied among these species. Differences in detectability of breeding males may partly explain why abundance and number of nesting pairs were related in some species and not in others. Variations in the availability and quality of habitat patches among plots could produce the different relationships I observed between abundance and reproductive success. My results suggest that measures of reproductive success as well as abundance should be used to determine habitat quality for breeding birds.

Abstract:
For migrant birds, the non-breeding season can greatly influence survival and future reproductive success. Knowledge of annual and overwinter survival, the degree of site fidelity and habitat use in the non-breeding season, migration ecology, routes and stopovers, and whether these differ with age or sex is fundamental to understanding population dynamics, vulnerability to anthropogenic habitat degradation, and consequently for understanding the severe widespread declines of migrant bird species. The degree to which a migrant is a winter specialist or generalist is likely to be central to understanding population dynamics. I studied survival rates and the wintering and migration ecology of a declining Palearctic migrant, the whinchat Saxicola rubetra, wintering in West Africa, to establish how the non-breeding season may influence migrant population dynamics. Whinchats were extremely site faithful to both within and between years, holding distinct winter territories and returning to those territories in subsequent winters, despite the opportunity to relocate. Overwinter survival was very high and annual survival was comparable to or higher than that reported on the breeding grounds. Because our power to detect resident and dispersing birds was high, survival rates likely estimated true survival well. Habitat characteristics varied widely across territories and territories were smaller if more perching shrubs and maize were present. Most individuals showed a tolerance or even preference for human modified habitats. Some individuals may have multiple wintering sites. There was no evidence of dominance-based habitat occupancy or any differences in winter ecology, site fidelity, survival and most aspects of migratory behaviour between age and sex classes. Migratory connectivity occurred only on a large-scale and individual migratory behaviour was also varied. Fundamentally, the results suggest a generalist strategy in the non-breeding season within their wintering habitat of open savannah, most likely as an adaption to stochastic site selection within the wintering range for juveniles undertaking their first migration plus changing and unpredictable conditions both within and between years. Consequently, wintering conditions may not significantly limit whinchat populations and mortality is probably highest during active migration. Notably, non-specialist migrants such as whinchats may have some resilience at the population-level to the increasing anthropogenic habitat modification occurring in Africa, suggesting that conditions during migration and in Europe may be driving declines; yet establishing the currently unknown thresholds of any resilience is likely to be fundamental for the future conservation migrants.

Abstract:
Per què alguns llinatges de vertebrats, incloent els humans, han evolucionat cervells grans és un dels grans trencaclosques de la biologia evolutiva. De les varies hipòtesis que s’han plantejat per intentar resoldre aquest misteri, la variació ambiental destaca com una de les principals causes de la variació en la mida relativa del cervell. Més formalment, la hipòtesis del cervell protector (CBH, de Cognitive buffer hypothesis”, en anglès) postula que els cervells relativament més grans han evolucionat per facilitar els ajustos de comportament per augmentar la supervivència en condicions canviants. Tot i que la CBH ha rebut suport empíric els darrers anys, alguns autors qüestionen la seva rellevància for explicar l’evolució del cervell argumentant que mantenir un cervell massa gran en períodes d’escassetat de recursos és massa costós, de manera que la variació ambiental hauria de limitar més que no pas afavorir l’evolució dels cervells grans. Aquesta tesi doctoral explora les causes i conseqüències de l’evolució de la mida del cervell, amb especial atenció en la CBH, validant les seves assumpcions, assajant les seves prediccions i avaluant les seves implicacions. La tesi treu profit d’una base de dades de mesures del cervell per més de 1900 espècies d’ocells en combinació amb els més recents mètodes filogenètics comparatius per tal de descobrir els orígens de la variació en la mida del cervell en la classe de vertebrats més diversa. Com a primer objectiu, aquesta tesi valida en quina mesura la mida relativa del cervell és una bona aproximació de la variació en estructures del cervell involucrades en la capacitat de construir respostes de comportament als nous reptes. El capítol 1 mostra que les àrees associatives del cervell, tradicionalment relacionades amb la intel·ligència general, són desproporcionadament més grans en espècies de cervell gran i poden predir de forma acurada la variació en el conjunt del cervell, de manera que es validi la seva utilització en anàlisis comparatives globals. Segons la CBH, les espècies que viuen en regions amb alta variabilitat ambiental haurien de ser seleccionades per cervells grans, a menys que tinguin adaptacions especialitzades per evadir les caigudes en la disponibilitat de recursos. El Capítol 2 mostra com els ocells que viuen en ambients més estacionals i impredictibles , com les regions de latituds altes, posseeixen cervells relativament més grans que els residents d’altres regions, recolzant la CBH en ocells. En el capítol 3 es mostra com els ocells que colonitzen illes oceàniques sembla que han evolucionat cervells relativament més grans que els seus parents continentals. Aquests canvis sembla que en part s’expliquen per un augment de la incertesa en la disponibilitat de recursos que caracteritza les illes, aportant una evidència addicional per la CBH. En el capítol 4 s’estudia el rol actiu del cervell en l’evolució. Tal com prediu la hipòtesi del behavioural drive (behavioural drive hypothesis en anglès), els ajustos de comportament més freqüents com a resposta als reptes ambientals hauria d’exposar els individus més sovint a nous conjunts de pressions selectives, tot afavorint la divergència evolutiva respecte els seus ancestres i finalment afavorint l’aparició de noves espècies. El capítol 4 mostra com els llinatges amb cervells relativament més grans han tingut majors taxes de diversificació taxonòmica. Aquesta troballa recolza així la idea que els animals no són agents passius de la selecció, però que poden modificar activament la seva relació amb l’ambient i influenciar el seu propi camí evolutiu. En resum, els resultats d’aquesta tesi aporten evidència empírica per la CBH, mostrant com els cervells relativament més grans funcionen, i per tant han evolucionat, per fer front als canvis ambientals, i que l’evolució de cervells grans pot a més influir en la diversificació evolutiva d’un llinatge.
Why some vertebrate lineages, including humans, evolved large brains is one of the main puzzles in evolutionary biology. Of the many hypotheses that have been launched to try to resolve this puzzle, environmental variability stands out as a major cause of relative brain size variation. More formally, the cognitive buffer hypothesis (CBH) postulates that relatively large brains evolved to facilitate behavioural adjustments to enhance survival under changing conditions. The rationale of the CBH is that advanced cognition can increase fitness in varying environments by enhancing information gathering and learning, facilitating for instance shifts between different feeding sites or food types to alleviate periods of food scarcity. While the CBH has received ample empirical support in recent years, some authors have questioned its relevance to account for the evolution of enlarged brains on the grounds that maintaining the brain during periods of food scarcity may be excessively costly, so environmental variability should constrain rather than favour the evolution of large brains. The present PhD thesis explores the causes and consequences of the CBH, validating its assumptions, testing its predictions and assessing its evolutionary implications. It takes advantage of a large database on brain size comprising more than 1900 extant bird species in combination with recently developed phylogenetic comparative methods to elucidate the origins of brain size variation in the most diverse vertebrate class. As a first objective, the thesis validates the extent to which relative brain size is a good proxy of the brain structures involved in the capacity to construct behavioural responses to new challenges. Chapter 1 thus shows that the associative areas of the brain, classically related with general intelligence, are disproportionally larger in large brained species and accurately predict variation in the whole brain, therefore validating its use in broader comparative analyses. According to the CBH, species living in regions with higher environmental variation should be selected for larger brains, unless they have adaptive specialisations to avoid drops in resource availability. Chapter 2 shows that birds living in highly seasonal and unpredictable environments, like high-latitude regions, possess relatively large brains than residents from other regions, supporting the CBH in birds. Additional support for the hypothesis is found in Chapter 3, where birds colonizing oceanic islands seem to evolve relatively larger brains than their continental relatives. These changes seem to be in part caused by the increased uncertainty in resource availability that characterizes islands, which together with limited chances to disperse and a trend toward slower life-history strategies can facilitate the evolution of enlarged brains. Finally, Chapter 4 explores the active role of brain size on evolution. As predicted by the behavioral drive hypothesis, frequent behavioral changes as a response to environmental challenges should expose individuals to new sets of selective pressures, thereby favouring evolutionary divergence from the ancestors. Chapter 4 provides evidence for the behavioural drive hypothesis, showing that avian lineages with relatively large brained have experienced higher diversification rates than those with smaller brains. This finding is in line with the view that animals are not passive agents of selection, but by actively modifying its relationship with their environment also influence their own pace of evolution. Overall, the findings of the present thesis provide empirical support for the CBH, showing that a relatively large brain functions, and hence may have evolved, to cope with environmental changes, and that the evolution of enlarged brains may subsequently influence the evolutionary diversification of the lineage.

Abstract:
The Amazon rainforest harbours -10% of the world's birds, and more than 400 species are regularly recorded at single sites. Understanding the processes behind the generation and maintenance of biodiversity, especially on this scale, has been a central theme in the study of evolution and ecology since Darwin. Amazonian speciation and diversification models emphasise the importance ofhiogeography, geological history, and interspecifi c interactions in generating one of the most biodivcrse biomes on earth. However, the inherent ecological traits of Amazonian taxa are rarely considered. The role of rivers in Amazonian diversification is contentious, and are-evaluation of the river barrier hypothesis in the light of species ecology is timely, as behavioural, distributional and phylogenetic data for Amazonian birds are more detailed and robust than ever before. By examining the relationship between 20 major rivers and the distribution of 739 species and their subspecies in a comparative framework, I investigate (i) the role of the Amazonian river system in shaping and driving av ian diversification; (ii) how river dynamics affect river barrier strength; and (ii i) how ecology influences clade diversification propensity. I also examine (iv) how niche space is shared and partitioned, in a case study investigating mechanisms pennilting the coexistence of two closely related species of antbird. I demonstrate that rivers act as important barriers for particular ecological groups, and are stronger baniers for subspecies than species, indicating a role in recent and ongoing intraspecific diversification; that barrier strength increases with river width; Ihal dispersal limitation is a key predictor of divers ification, with higher subspecies richness in groups with poor dispersal; and that species coexistence is mediated by high levels of niche overlap. Taken together, these studies suggest that species ecology, dispersal limitation and river barriers interact to playa major role in structuring, generating and maintaining Amazonian avian biodiversity.

Abstract:
The movements of nomadic species are poorly understood, being highly dynamic over time and space. There is an urgent need to better understand this group as current conservation approaches appear not to be providing adequate protection. In this thesis, I evaluate a survey method to monitor this dynamic group, assess environmental variables driving their movements over time, and explore how rainfall structures the overall avian community. To date, no standardized, large-scale monitoring has been carried out for arid zone or nomadic species. In Chapter 2, I describe a protocol for surveying this group over five years using two survey methods. Detection probabilities and robust density estimates were generated for 64 species and showed the majority fluctuated markedly over time. Line transect surveys were more effective for species richness and abundance measures. This survey method provides the first standardized density estimates for this assemblage and can be easily repeated in future for this and other remote, arid biological communities. The movement characteristics of species with unpredictable, aseasonal movements are very poorly understood and difficult to measure. In Chapter 3, I develop a method for quantifying extent of bird movement by analysing changes in species’ site persistence and variability in inter-annual densities over time, and compare results with existing movement classifications. Continuous variation in extent of species movement indicated that a binary grouping of resident versus nomadic species is inappropriate. Existing movement classifications likely underestimate species movements within arid regions of their distribution, suggesting that caution is needed when using sweeping species-level classifications, especially for Australian birds whose movements can be heavily environment-dependent. Unlike regular migration, which is triggered by seasonal cues such as day length and temperature, movement in nomads is thought to be triggered by less predictable environmental conditions. In Chapter 4, I explore the relative influence of dynamic and static environmental variables on species abundance. Dynamic variables were more important for nomadic versus resident species but static variables were equally important for nomadic and resident species. These findings suggest that habitat structure is important to consider in addition to dynamic environmental features for understanding nomadic species movements. Pulse events are thought to be positively correlated with nomadic species movements and to play an important role in structuring arid biological communities. In Chapter 5, I investigate how structural changes observed in Australia’s arid bird community relate to rainfall and vegetation greenness. The importance of rainfall was mediated through vegetation growth and the community is dynamic at a local level but exhibits stability at a landscape level, underscoring the importance of connectivity between suitable habitats within this landscape to enable species to reshuffle among sites. In sum, my thesis highlights the importance of standardized data for enabling an empirical approach to understanding nomadic and arid-zone bird species. Findings will advance our understanding of these species’ dynamics and lay groundwork for improving protection of this group by identifying further research priorities.

Abstract:
Pests can impact significantly upon the economy, the environment and on human and animal health. However, for pest birds there are surprisingly few studies of these impacts and how to reduce them. The aim of this thesis is to advance our understanding of the ecology, impacts, and management of pest birds using case studies for each of the three main impacts. In considering economic impacts I estimate pest bird abundance, describe a novel method for measuring bird damage, and evaluate the efficacy of lethal and non-lethal methods in vineyards and orchards. Using data across 185 property years, netting was found to be the most effective in reducing bird damage. Shooting was not as effective but was one-third of the cost and had 13% lower damage compared with nil-treatments. Scaring with electronic devices and visual deterrents had no effect on bird damage. Despite their widespread use, lethal methods had limited effectiveness for reducing pest abundance. In considering environmental impacts introduced mallards on Lord Howe Island were used as a case study. Phenotypic characteristics suggest that mallards have supplanted the native Pacific black duck on Lord Howe Island. Management alternatives are evaluated and discussed. In considering health-related impacts wild birds and avian influenza in Australia was used as a case study. Here, the ecology of Australia’s Anseriformes, and the epidemiology, modes of transmission, and the factors influencing the prevalence of avian influenza in Australia’s wild birds are investigated. Risk profiles to improve the efficiency and relevance of wild-bird surveillance are also provided. The case studies presented demonstrate that an understanding of a pest’s ecology, efficient measures of impacts, and thorough evaluations of surveillance and management strategies are essential for effectively managing their economic, environmental and health-related impacts.

ENGLISH ABSTRACT: Forests in South Africa have had a long history of human utilization and disturbance, and are under threat from a variety of anthropogenic land use changes. Foremost of these are deforestation and forest degradation, impacting the species native to these forests. The aims of this study were to determine changes in the distribution of forest dependent bird species according to the South African Bird Atlas Project; to relate these changes to changes in land-use; to identify links between these changes; to determine the extent, location and causes of the decline of each forest dependent bird species; and to identify current risks to forest dependent bird species in South Africa. Range data on 57 forest dependent bird species from SABAP1 (1987-1992) and SABAP2 (2007-present) were analyzed. Of these, 28 species were found to have declining ranges. Thirty sites across South Africa were identified as being most at risk, with all having experienced a loss of more than 10 of the 57 forest dependent bird species between SABAP1 and SABAP2. The range change data of the 28 species with decreasing ranges were correlated with data on changes in land cover over the same time period to infer relationships between changes in land use and change in bird ranges. Occupancy modelling was done to determine which land cover types affect extinction and initial presence. Individual species characteristics were analyzed to determine links between characteristics and response to land use change. A pan-European trait-based risk assessment framework was applied to all 57 species to identify habitats and species most at risk, as well as the most important threats to species persistence. Results showed that natural vegetation decreased in 67% of sites, while plantations and cultivation increased in 50% of sites. Occupancy modelling showed extinction likelihood to increase with plantations in some species, while plantations mitigated extinction likelihood in other species. Urbanization and cultivation likewise mitigated extinction likelihood in some species. Natural vegetation was replaced by cultivation, while cultivation was replaced by urbanization. The number of species lost increased with a loss of natural vegetation. Twenty two of the thirty sites experienced deforestation of indigenous forests between 2000 and 2013/2014; changes in natural vegetation in these sites can be attributed primarily to deforestation, and a loss of plantations. While most at-risk sites were in the Eastern Cape, there was no geographic grouping of species loss or of land use change. Most species lost were birds of prey or insectivores, and species characteristics and habitat preferences determined the sites from which they were lost. The Cape parrot (Poicephalus robustus), rufous-chested sparrowhawk (Accipiter rufiventris) and the migratory Eurasian golden oriole (Oriolus oriolus) suffered the largest declines in range size and are thought to be most at risk. Montane forests were found to be more at risk than other forest types. The major risks facing montane forests were increased abundance of small predators, increased fire suppression, increased soil management, removal of deadwood and reduced diversity of tree species. These threats are all products of plantation forestry and local harvesting. Nesting risk was higher than foraging risk for all species, indicating that nesting habitat should be better preserved. Half of South Africa’s forest dependent bird species have declining ranges, with the loss of these species most prominent in the Eastern Cape. Natural vegetation loss, comprising mostly recent deforestation; increased cultivation and urbanization; and changes in plantation cover are thought to be the main factors determining these declines. Montane forests in particular should be better protected to preserve forest dependent species, and the negative effects of plantation forestry and local harvesting should be mitigated.
AFRIKAANSE OPSOMMING: Suid-Afrika het ‘n lang geskiedenis van woude wat deur mense gebruik, asook vernietig word. Woude word bedreig deur verskeie menslike grondgebruike en veranderinge. Die mees vooraanstaande van die bedreigings is ontbossing en woud verdunning, wat ‘n invloed het op inheemse spesies in die woude. Die doelwitte van hierdie studie was om veranderinge in die verspreiding van bos-afhanklike voëlspesies vas te stel volgens die Suid Afrikaanse Voël Atlas Projek; om hierdie veranderinge te verband met veranderinge in grondgebruik; om verbande tussen hierdie veranderinge te identifiseer; om die mate, die plek en die oorsake van die agteruitgang van elke bos-afhanklike voëlspesies te bepaal; en om huidige risiko's aan die bos afhanklik voëlspesies in Suid-Afrika te identifiseer. Trefwydte inligting oor 57 woud afhanklike voëlspesies van SABAP1 (1987-1992) en SABAP2 (2007-nou) was geanaliseer. Daar was gevind dat vanuit die spesies, het 28 ‘n afneming in trefwydte ervaar. Dertig terreine in Suid-Afrika was uitgeken as dié met die hoogste risiko, met ‘n verlies van meer as 10 van die 57 woud afhanklike voëlspesies tussen SABAP1 en SABAP2. Die trefwydte inligting van die 28 spesies met ‘n afnemende trefwydte was gekorreleer met inligting oor veranderinge in grond bedekking oor dieselfde tydperk om verhoudings tussen veranderinge in grond gebruik en veranderinge in voël trefwydtes aftelei. Besetting modellering was gedoen om te bepaal watter tipes grond bedekking beinvloed uitwissing en aanvanklike teenwoordigheid. Kenmerke van individuele spesies is ontleed om verbande tussen kenmerke en reaksie op verandering in grondgebruik te bepaal. ‘n Pan-Europese eienskap gebaseerde risiko-analise raamwerk is toegepas op die 57 spesies om die spesies en habitatte met die grootse risiko te identifiseer, asook die belangrikste bedreigings vir spesies-volharding. Die resultate het gewys dat natuurlike plantegroei het verminder in 67% van terreine, terwyl plantasie en verbouing vermeerder het in 50% van terreine. Besetting-modellering het gewys dat waarskynlikheid van uitwissing vermeerder met plantasies in sommige spesies, terwyl plantasies die waarskynlikheid van uitwissing verminder het in ander spesies. Verstedeliking en verbouing het ook die waarskynlikheid van uitwissing verminder in sommige spesies. Natuurlike plantegroei was vervang deur verbouing, terwyl verbouing vervang is deur verstedeliking. Die aantal spesies verlies het vermeerder met die vermindering van natuurlike plantegroei. Twee en twintig van die dertig terreine het ontbossing van inheemse woude ervaar tussen 2000 en 2013/2014. Veranderinge in natuurlike plantegroei in die terreine is meestal as gevolg van ontbossing, en ‘n vermindering van plantasies. Terwyl meeste van die hoë risiko terreine in die Oos-Kaap was, was daar geen geografiese groepering van spesies vermindering of grondgebruik veranderinge nie. Meeste spesies wat vernietig is was roofvoëls of insectivore, en spesies kenmerke en habitat voorkeure het die terreine bepaal waaruit hulle verloor is. Die grootpapegaai (Poicephalus robustus), rooiborssperwer (Accipiter rufiventris) en die trekvoël Europese wielewaal (Oriolus oriolus) het die grootste vermindering in trefwydte grootte ervaar, en is vermoedelik die grootste risiko. Bergwoude was gevind om meer in gevaar te wees as ander woud tipes. Die grootste risikos wat bergwoude beïnvloed het was ‘n toenemende hoeveelheid klein roofdiere, verhoogde vuur onderdrukking, verhoogde grondbestuur, verwydering van dooie hout, en verlaagde diversiteit van boomspesies. Hierdie bedreigings is almal as gevolg van plantasie bosbou en plaaslike oes. Nes-risiko was hoër as kos soek risiko vir alle spesies, wat aandui dat nes-habitat beter bewaar moet word. Die helfte van Suid-Afrika se woud-afhanklike-voëlspesies het dalende trefwydtes, met die verlies van hierdie spesies mees opvallend in die Oos-Kaap. Die verlies van natuurlike plantegroei, as gevolg van onlangse ontbossing; verhoogde verbouing en verstedeliking; en veranderinge in plantasie bedekking is vermoedelik die hooffaktore wat die vermindering van voëlspesies veroorsaak. Veral bergwoude moet beter beskerm word om woud-afhanklike-voëlspesies te bewaar en die negatiewe invloede van plantasiebosbou en plaaslike oes te verminder.

Abstract:
AbstractAlthough birds have always been one of the best-known taxa on the Gulf of Guinea oceanic islands, our understanding of their ecology and evolution has increased substantially in the last two decades. Intensive field-based surveys have allowed the first detailed island-wide distribution maps for most species and a much better grasp of habitat associations, highlighting the importance of native forests for many of the endemic birds. Molecular data have provided important insights into evolutionary history, leading to an extensive revision of the taxonomy of the islands’ endemic avifauna. Most speciation events are much more recent than the age of the islands, indicating a high species turn-over that is likely explained by the islands’ history of intense volcanic activity and their moderate distances to the mainland. These islands have the highest accumulation of endemic bird species for small oceanic islands: at least 29 endemic species occur in three islands with a total area of just over 1000 km2. This may be explained by their particular geographic location: offshore from a species-rich continent at distances that allowed the colonization and evolution in isolation of many distinct lineages. All these contributions are now being used to ensure bird conservation, through updated species conservation status and species action plans for the most threatened species, and also to promote the conservation of the native forests on which most of the endemic birds depend.

Abstract:
The article discusses the features of the ecology of birds in the parks of Minsk. The territorial heterogeneity of quantitative indicators of the bird population was determined. Factors that threaten birds in urban areas have been identified. Measures are proposed to preserve the species diversity of the avifauna and improve the ecological conditions of habitats in the parks of the capital, such as the creation of special recreation areas for people on the outskirts of park areas, conservation of tree species, planting trees and shrubs, conservation of forest litter, installation of artificial nests and feeders, use for night lighting more modern lighting fixtures, promoting the protection and conservation of the avifauna, educating citizens in a humane and caring attitude towards the animal world. It is concluded that the conservation of bird biodiversity should be addressed in a comprehensive manner, depending on the ecological specifics of a particular bird species and a particular park.

In this work, we determined the number and systematic affiliation of the most common bird species of the Voronezh upland oak forest in the territories exposed to anthropogenic impact. Field studies were carried out from 2019 to 2020 on the territory of the Voronezh upland oak forest. At the sites selected for the survey, a route counting of birds by voices was carried out. The species composition of the avifauna was supplemented by an analysis of information about the habitat of birds and their nesting sites in areas with constant recreational impact. At the selected sites, birds were counted by voices (mating song). From the results of counts in the studied areas, one can see the diversity of the species composition of the avifauna during the reproductive period. Analysis of the data obtained makes it possible to determine the ecological belonging of the species and compare the quantitative indicators of the birds encountered.

Abstract:
The aim of the paper was to highlight the interdependence between wild and domestic birds in the transmission of various forms of parasitic agents. Domestic poultry (hens, turkeys, ducks, geese) recorded an infestation of 13 species of malophagous (Cuclotogaster heterographus, Eomenacanthus stramineus, Goniocotes gallinae, Goniocotes maculatus, Goniades dissimilis, Menopon gallinae, Menacanthus pallidulus, Menacanthus cornutus, Lipeurus caponis, Chelopistes meleagridis, Anatoecus dentatus, Anatoecus icterodes). For hens were recorded 10 species of malophagous (Cuclotogaster heterographus, Eomenacanthus stramineus, Goniocotes gallinae, Goniocotes maculatus, Goniodes dissimilis, Menopon gallinae, Menacanthus pallidulus, Menacanthus cornutus, Lipeurus caponis, Chelopistes meleagridis), of which Chelopistes meleagridis species are occasional, 2 flea species (Ceratophylus gallinae, Ceratophylus hirundinis) and 3 gamma-acarian species (Dermanyssus gallinae, Dermanyssus hirundinis and Knemidocoptes mutans). It has been established that wild birds of hunting interest (pheasants, quails, geese, wild ducks) hane miximvasions with a wide variety of ectoparasites: 10 species of malophagous (Cuclotogaster cinereus, Goniocotes chrysocephalus, Goniodes colchici, Cuclotogaster heterographus, Eomenacanthus stramineus, Menopon gallinae, Menacanthus stramineus, Anaticola crassicornis, Anatoecus dentatus, Anatoecus icterodes, of which 9 species (Cuclotogaster heterographus, Eomenacanthus stramineus, Menopon gallinae, Goniocotes gallinae, Goniodes dissimilis, Lipeurus caponis, Anaticola crassicornis, Anatoecus dentatus are common for domestic birds, 2 flea species (Ceratophylus gallinae, Ceratophylus hirundinis) and 3 species of parasitic mites (Dermanyssus gallinae, Dermanyssus hirundinis and Knemidocoptes mutans), which have been established in domestic poultry.

Abstract:
The article presents the characteristic of the systematic composition and diversity of skeletal remains of mammals in the third level of human habitation of the Paleolithic site in the cave of Brânzeni I, Edinet district. The archaeological and paleontological remains discovered here are attributed to a new archaeological culture for Europe – Brânzeni. The inhabitants of this site hunted horses, reindeer, bison, deer, rhino, mammoth, hares, marmot and other mammals, that met in thesite area and were the main source of food for tribal members. The bones of small animal species (insectivores, rodents etc.) discovered in the inhabiting level of the Palaeolithic site originated from the decomposition of predatory bird pellets and of the feces of carnivores living in the cave while it was temporarily abandoned by the Paleolithic hunters. The archaeological and paleontological materials presented in this information are of interest for the knowledge of the peculiarities of geological history, fauna of paleogeography and the human society of the given area, have instructive, cognitive and ecotouristic value.
