Full textAbstract:
Eight species of hemoparasites (Plasmodium relictum, Plasmodium elongatum, Plasmodium sp.indet., Haemoproteus plataleae, Haemoproteus herodiadis, Haemoproteus sp.indet., Leucocytozoon ardeae, and Trypanosoma avium) were found in thin blood films from 402 wading birds in Florida. Three of 11 ciconiiform species were infected, including the tricolored heron (Egretta tricolor), white ibis (Eudocimus albus), and two subspecies of Ardea herodias, the great blue heron (Ardea herodias herodias) and great white heron (Ardea herodias occidentalis). Representatives of each genus of hemoparasite except Leucocytozoon were recorded in nestlings, indicating that transmission occurred in Florida. Infections by L. ardeae were more common in northern Florida than in southern Florida. Species of Plasmodium and Haemoproteus were more commonly transmitted to nestling great blue herons in freshwater colony sites than in salt-water colony sites.

Full textAbstract:
In the present study, we examined the role of different habitat components and their relationship with microhabitat use by three species of egret: Cocoi heron (Ardea cocoi), Great egret (Ardea alba), and Cattle egret (Bubulcus ibis), in wetlands of southern Brazil. Ardea alba and A. cocoi were not habitat-specific (e.g. vegetation cover and flooding level). Conversely, B. ibis was associated with drier microhabitats. Relative air humidity and air temperature were the main variables which correlated with the occurrence of these species and supported the plasticity of B. ibis and its predominance in drier habitats.

Full textAbstract:
Aerial surveys between 1981 and 1984 were used to identify monthly trends in the abundance of Pacific herons (Ardea pacifica), pied herons (Ardea picata), cattle egrets (Ardeola ibis), great egrets (Egretta alba), little egrets (Egretta garzetta), intermediate egrets (Egretta intermedia), glossy ibis (Plegadis falcinellus), sacred ibis (Threskiornis aethiopica), straw-necked ibis (Threskiornis spinicollis) and royal spoonbills (Platalea regia) on five floodplains of the Alligator Rivers region, 250 km east of Darwin in the monsoonal Northern Territory. Ground surveys were conducted during the same period on one of the floodplains, the Magela. The aerial surveys indicated that the Magela floodplain was inhabited by few of these birds during the wet season (November-March), but that numbers then increased substantially in the dry season. The Nourlangie floodplain and Boggy Plain (a large backswamp of the South Alligator floodplain) showed similar patterns, but the numbers of birds tended to be lower. Birds were generally uncommon on the shallower East Alligator and Cooper floodplains, except for egrets in the wet season. Ground surveys suggested that the birds sought out the persistent swamps that characterise the Magela foodplain in the dry season. Ground surveys also indicated that aerial surveys underestimated densities. On the basis of correction factors calculated from ground surveys, peak numbers on the five floodplains were roughly estimated to be about 4000 pacific herons, 50 000 pied herons, 300 000 egrets (primarily intermediate egrets), 60 000 glossy ibis, 16 000 sacred ibis, 80 000 straw-necked ibis and 35 000 royal spoonbills. Great-billed herons (Ardea sumatrana), white-faced herons (Ardea novaehollandiae), striated herons (Butorides striata), rufous night herons (Nycticorax caledonicus), black bitterns (Dupetor flavicollis) and yellow-billed spoonbills (Platalea flavipes) were recorded sporadically in low numbers. The Alligator Rivers region acted as a dry-season refuge for herons, egrets, ibises and spoonbills because of the unusually persistent fresh waters of the Magela and Nourlangie floodplains and some of the backswamps of the South Alligator, such as Boggy Plain.

Los ecosistemas acuáticos son susceptibles de la contaminación, siendo los metales tóxicos compuestos que generan impactos deletéreos en los organismos. La mayoría de estos, se bioacumulan en la cadena trófica y cuantificar su concentración en los tejidos de las aves acuáticas puede determinar su impacto ambiental. Por lo tanto, el objetivo de este estudio es determinar la concentración de mercurio, plomo, arsénico o cadmio en las plumas de la garza grande (Ardea alba), la corocora (Eudocimus ruber) y el ibis de cara roja (Phimosus infuscatus), especies que habitan cerca al río Ocoa de Villavicencio-Meta, Colombia. Para este fin se realizará un recorrido preliminar identificando puntos claves de nidales de la corocora (Eudocimus ruber), el ibis de cara roja (Phimosus infuscatus) y la garza grande (Ardea alba). Posteriormente, se seleccionarán seis diferentes lugares de recolección de las plumas, donde de cada especie se colectarán y clasificarán las plumas (n = 3 por punto) y se almacenarán en bolsas herméticas para llevar al laboratorio, donde se realizará una preparación para proceder al envío a un laboratorio de referencia, donde se determinarán los metales tóxicos a través de espectrometría de absorción atómica (AA). Los resultados serán analizados a través de una ANOVA de dos vías y un test de Tukey (p<0,05). Al finalizar este estudio se espera determinar la concentración de al menos un metal tóxico en las plumas de las garzas Corocora, Garza Grande y el Ibis de Cara Roja, demostrando su potencial como biomarcadores confiables no invasivos para el estudio de ecotoxicología en la región, permitiendo concientizar a la población del sector sobre la importancia de la conservación del medio ambiente y el riesgo potencial de los metales tóxicos sobre la salud animal y ambiental.

Full textAbstract:
Heron colonies are dynamic components of wetlands. Therefore, their systematic monitoring is important for the management of both birds and wetlands. During the period 1988–2018, we counted breeding pairs of seven colonial breeding heron species at 65 colonies across 37 wetlands in Greece. We considered as annual variables of a population: (a) years since 1988, (b) Natura 2000 network inclusion, (c) protected area management authority overseeing, (d) wetland type (new or restored), and (e) new colonies (established after 2003). The Cattle Egret Bubulcus ibis and the Squacco Heron Ardeola ralloides had a positive breeding population trend. The Black-crowned Night Heron Nycticorax nycticorax, Little Egret Egretta garzetta, and Grey Heron Ardea cinerea had a negative trend, while the Purple Heron Ardea purpurea population was stable. The Great White Egret Ardea alba bred sporadically at only a few sites which precluded the evaluation of its population trend. The informative population variables differed among species, even of those at the same colony, which suggests trends are also affected by conditions at wintering grounds. The study highlights the need for the systematic monitoring of heron colonies and the protection of foraging/breeding areas in order to reverse the observed negative population trends.

Dynamics of the aquatic nesting bird populations in the mixed colonies from Vulpaşu, Chiriloaia and Cucova (Balta Mică a Brăilei Nature Park, Romania) This study presents the observations made during a three-year period of time (2007-2009) in the three mixed colonies of the Balta Mică a Brăilei Nature Park: Vulpaşu, Chiriloaia and Cucova. In the colonies, there was reported a number of ten aquatic nesting species, with specific differences for each colony separately. The 10 species are: Phalacrocorax carbo (Great Cormorant), Phalacrocorax pygmaeus (Pygmy Cormorant), Nycticorax nycticorax (Night Heron), Ardeola ralloides (Squacco Heron), Egretta garzetta (Little Egret), Egretta alba (Great White Egret), Bubulcus ibis (Cattle Egret), Ardea cinerea (Grey Heron), Plegadis falcinellus (Glossy Ibis) and Platalea leucorodia (Spoonbill). The presence or absence of certain species in a colony is closely related to its ecological requirements, with the structural features of the ecosystems and the climatic conditions.

Full textAbstract:
The diversity of micro-habitats in tropical wetlands allows the coexistence of several species. These sympatric species interact with each other, either directly or indirectly, to optimally use the available resources. They achieve this through niche separation or minimal overlap to avoid competition. India’s wetland ecosystems are home to various sympatric species, such as the Great Egret Ardea alba (GE), Median Egret Ardea intermedia (IE), Little Egret Egretta garzetta (LE) and Cattle Egret Bubulcus ibis (CE). These egret species are closely related, and as a result, have similar niche requirements, which could lead to high intra-specific competition. However, there have been few studies on how these species utilize resources. This study aims to understand the possible mechanisms that enable the coexistence of these species in a tropical wetland. We have examined habitat characteristics, feeding behaviour, timings of seasonal and daily activities, and spacing patterns to evaluate possible models of species coexistence. We discovered that these four sympatric egret species have differences in microhabitat selection, activity patterns, both daily and seasonally, and feeding preferences. The study further indicates that there is a relationship between the niche dimensions, but it is only partially dependent on each other.

Las garzas que se reproducen en colonias presentan requerimientos ecológicos similares e intensifican sus relaciones interespecíficas. Sin embargo, estas especies pueden coexistir al segregarse temporal y espacialmente. Se estimó el número de nidos de ocho especies de garzas (Ardea alba, Egretta thula, E. caerulea, E. tricolor, E. rufescens, Bubulcus ibis, Nycticorax nycticorax y Cochlearius cochlearius) durante la temporada reproductiva marzo a agosto de 2018 en Isla Pájaros, Laguna Mar Muerto, Oaxaca- Chiapas, México. Así mismo, se estimaron las abundancias de las parejas reproductoras, el patrón temporal y espacial de reproducción por especie, y se describió el sitio de anidación. Se contaron nidos en 96 parcelas y se midieron ocho variables ambientales. Se registraron 1018 nidos, donde B. ibis presentó el mayor número de parejas reproductoras (299), seguida por E. tricolor (213) y E. thula (142). Las especies menos abundantes fueron C. cochlearius (35) y E. caerulea (33). La distribución de los nidos en la isla varió espacial y temporalmente entre parcelas al igual que la composición de especies y la abundancia de nidos por parcela (P < 0,001). Se registró una distribución vertical en la construcción de los nidos de al menos tres especies, mientras que las cuatro garcitas de similar tamaño (E. thula, E. caerulea, E. tricolor y B. ibis) anidaron juntas en las partes intermedias. Se registraron agrupaciones entre las especies y características de la vegetación. Los patrones de distribución espacial y temporal de estas especies permiten entender el uso de un recurso común durante la reproducción.

Full textAbstract:
AbstractSeveral waterbird species prey on fishes, and usually use only one sensory mode to detect this prey: herons hunt visually guided, whereas ibises mostly search tactilely guided. I report herein events in which a heron and an ibis caught and released a poisonous fish at a mudflat in southeastern Australia. A Great Egret (Ardea alba) that targeted small gerreid fishes caught and immediately released the very toxic pufferfish Tetractenos hamiltoni, with bill washing and discomfort movements afterwards. Two Australian White Ibises (Threskiornis molucca) that probed for bottom-dwelling fishes and crabs caught and handled these pufferfishes for about 60 s, before releasing them. Next, the birds dipped the bill in the water and resumed hunting. Pufferfishes are rarely preyed on by birds, but an Australian bird that feeds on this fish type is the Silver Gull (Chroicocephalus novaehollandiae), which eats the pufferfish Torquigener pleurogramma when it is nontoxic or less harmful.

Full textAbstract:
Food supply is commonly regarded as ultimately controlling the size of bird colonies. Most studies examining this problem have been on seabirds, and all in the Northern Hemisphere. To search more widely for evidence of the importance of food as a factor controlling the size of bird colonies, we investigated egret colonies in a Southern Hemisphere region. We examined the relationship between colony size and the area of potential feeding habitat around each colony, compared with variables associated with the location and the physical characteristics of each colony. All colonies (13 in total) along 800 km of coastline in New South Wales, Australia, were studied. Colony size ranged from 7 to more than 2000 nests. There were very few correlations between the number of nests and the areas of different types of feeding habitat within 20 km of colonies. However, the available area of saltmarshes proved to be a significant predictor of colony size for great (Ardea alba), intermediate (A. intermedia) and little egrets (Egretta garzetta). Saltmarshes may be stable, long-term feeding habitats for these three native ‘aquatic feeders’, but not for the terrestrially feeding cattle egret (Ardea ibis). Nest numbers of this latter species were related positively to the area of saltmarshes, and negatively to latitude, suggesting that nest numbers of this exotic species may be influenced by climate, with proximate factors such as colonial nesting with the three native species also being important. Because of the numerical dominance of cattle egrets, the numbers of nests of all species followed the same pattern as that for cattle egrets.

Full textAbstract:
Abstract Mercury, a common wetland pollutant, can affect wildlife populations through acute toxicity or through physiological effects that modify behavior and negatively influence reproductive success. We compared body-feather mercury concentrations of free-living male and female adult White Ibises (Eudocimus albus) during three breeding seasons in the Florida Everglades and examined the relationships among mercury, hormone concentrations, and body-condition scores. Female White Ibises consistently had lower mercury concentrations than males. Prebreeding females' estradiol concentrations were negatively correlated with mercury concentrations. However, we found no relationship between mercury and female testosterone, progesterone, and corticosterone concentrations. Incubating male White Ibises showed a significant positive relationship between testosterone and mercury concentrations, but no other significant hormonal correlations with mercury concentrations. We used a seven-year standardized data set of Great Egret (Ardea alba) chick-feather mercury concentrations as a measure of temporal changes in mercury bioavailability in the Everglades and related that measure to annual numbers of White Ibis nests. White Ibis nesting was negatively correlated with the mercury exposure index. Low numbers of nesting White Ibises may have been the result of fewer birds nesting or high abandonment rates. Our results suggest that mercury exposure may cause fewer birds to nest or more birds to abandon nests because of subacute effects on hormone systems. However, the results are correlative; they call for further investigation in free-living populations and in the laboratory.

Full textAbstract:
Abstract The dynamics of foraging habitat use by long-legged wading birds was analyzed with respect to water-level fluctuation patterns in Florida Bay. Wading-bird presence at four sites situated to sample the heterogeneity of the bay was quantified by repeated surveys collected throughout the day and year. Models for habitat availability were generated using water-level data collected from continuous recorders, staff guages, and habitat profile maps. These models were tested against the survey data. Roseate Spoonbills (Ajaia ajaja) foraged on the study areas primarily at night. Great Blue Herons (Ardea herodias) fed both day and night, but primarily at night where the tidal range was small. Great Egrets (Casmerodius albus), Snowy (Egretta thula) and Reddish (E. rufescens) egrets, Little Blue (E. caerulea) and Tricolored (E. tricolor) herons, and White Ibis (Eudocimus albus) fed during daylight. Where tidal range was small (<5 cm) diurnal species fed throughout the day. Florida Bay has a pronounced annual water-level cycle that causes monthly mean water levels to vary by as much as 30 cm between October (high) and May (low). Models derived from hydrology data predicted that this seasonal variation in water level would have a major impact on habitat availability, particularly where tidal flux was small. The predictions were supported by survey data. At sites with minor tides, most wading-bird species had a cycle in seasonal abundance that correlated with seasonal changes in water level; only the tallest species, Ardea herodias, was uniformly present throughout the year. The large daily range in tide (x̄ = 80 cm) afforded year-round access to foraging habitat, and these abundance patterns did not exist. The seasonal variability in habitat availability has major management implications because the maintenance of stable wading-bird populations depends on the availability of alternative foraging sites when water levels are high. Historically, these sites have tended to be targeted for human development.

Patisar lake is an important wetland for migratory birds in mid-winter which is located in the center of the Lal Suhanra National Park of Bahawalpur, Pakistan. In this study Patisar lake has been explored to find out the endangered bird species. We used a map, a pencil, a notebook, a watch that is used to show seconds and binoculars for the census. Point counting system is used for the monitoring of birds and their habitat requirement was also measured. Result of the study indicated that these population belonging to 6 different orders, 10 different families, 18 genera and 32 different species of waterfowl were observed (1) Podicipediformes iPodicipedidae; iTachybaptus iruficollis), (2) Pelecaniformes (Family: Phalacrocoridae; Phalacrocorax iniger; P. carbo; Family; Anhingidae, Anhinga melanogaster), (3) Ciconiiformes (Family: Ardeidae, Ardea cinerea, A. purpurea, Ardeola grayii, Bubulcus ibis, Egretta alba, E. garzetta, E. intermedia), (4) Anseriformes (Family: Anatidae; Anas acuta, A. crecca, A. platyrhynchos, A. strepera, A. penelope, A. clypeata, Aythya ferina, A. fuligula, A. nyroca), (5) Gruiformes (Family: Rallidae: Fulica atra, Porphyrio porphyrio, Gallinula chloropus) and (6) Charadriiformes (Family: Recurvirostridae, Himantopusi himantopus; Family: Charadridae, Vanellusi indicus, V. vanellus, V. leucurus, Charadrius dubius; Family: Scolopacidae, Tringa tetanus, T. nebularia, Actitis hypoleucus; Family: Laridae,Sterna aurantia). According to They all preferred fresh water layer of the lake and marshes near the lake as their habitat. It was concluded that Patisar lake is a prodigious natural resource for the migratory waterfowl and the number of waterfowl declining with the passage of time.

Full textAbstract:
The concentration of 12 elements (As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn) has been investigated in the feathers of three species of Ardeidae, namely the Grey Heron Ardea cinerea, the Little Egret Egretta garzetta, and the Cattle Egret Bubulcus ibis, all breeding at a colony located in the southern Padana Plain (NW Italy). This study is a first step for an evaluation of possible direct effects of these elements on chicks’ survival and growth rate. Fe, Zn, Cu, and Mn were in the range 7–69 mg Kg−1, while lower levels of Pb, Ni, As, and Se (0.27–1.45 mg Kg−1) were measured. Co, Cd, and Cr were close to the method detection limits (MDLs) in all the species. The measured concentrations of the most abundant trace elements, such as Zn and Cu, seem to reflect the geochemical pattern of the background (running water and soil), while Hg concentration is lower and it appears to be biomagnified, particularly in Grey Heron feathers. Its concentration is higher in adults than in chicks, and it differs among the three species, as it is closely related to the fish-based dietary pattern. The measured trace elements’ concentrations are below the threshold levels in all the heron species, and consequently, harmful and acute effects on the local population are unlikely; the conservation status of herons populations in northern Italy is probably more affected by other factors, such as climate changes, altered aquatic environment, and, consequently, food quality.

Desportesius Chabaud and Campana, 1949 is revised. Eight species are recognized: D. brevicaudatus (Dujardin, 1845), D. bubulcusi (Kumar and Gupta, 1979), D. equispiculatus (Wu and Liu, 1943), D. invaginatus (Linstow, 1901), D. longevaginatus (Molin, 1860), D. orientalis (Wu, 1933), D. sagittatus (Rudolphi, 1809), and D. triaenucha (Wright, 1879). Desportesius spinulatus Chabaud and Campana, 1949, D. morneti Gretillat and Morel, 1961, D. cramae Sharma, 1973, D. nigeri Gupta and Kazim, 1978, and D. ibisi Naidu, 1981 are considered synonyms of the type species, D. invaginatus. Desportesius canadensis is regarded as a synonym of D. triaenucha. Three species are regarded as species inquirendae: Synhimantus ardeai Agrawal, 1965, D. groffi (Li, 1934), and D. raillieti (Skrjabin, 1924). Desportesius invaginatus, D. brevicaudatus, D. triaenucha, and D. longevaginatus are redescribed and a key to species is provided. Although Desportesius and Syncuaria Gilbert, 1927 have dissimilar cordon arrangements they may be closely related on the basis of the following shared characters: (i) monodelphy, (ii) vulva located immediately anterior to anus, (iii) highly inflated male caudal alae, (iv) preanal caudal papillae located immediately anterior to anus, and (v) short male and female tails.

Registramos la presencia y abundancia de aves, así como el hábitat y temporalidad de la reproducción de especies en las islas Pájaros, Venados, Lobos, Hermano Norte y Hermano Sur, ubicadas en la bahía de Mazatlán. Realizamos siete recorridos entre noviembre de 2014 y mayo de 2015; además contábamos con información colectada en mayo de 2004. Observamos un total de 59 especies de aves, de las cuales 15 fueron reproductoras: Dendrocygna autumnalis (pijije ala blanca), Phaethon aethereus (rabijunco pico rojo), Sula leucogaster (bobo café), Pelecanus occidentalis (pelícano café), Ardea herodias (garza morena), Ardea alba (garza blanca), Egretta thula (garza pie dorado), Bubulcus ibis (garza ganadera), Nycticorax nycticorax (pedrete corona negra), Nyctanassa violacea (pedrete corona clara), Eudocimus albus (ibis blanco), Coragyps atratus (zopilote común), Haematopus palliatus (ostrero americano), Larus heermanni (gaviota ploma) y Falco peregrinus (halcón peregrino). Para P. aethereus y S. leucogaster no había reportes previos de reproducción en estas islas; además, confirmamos la anidación de L. hermanni. La isla Pájaros fue la que albergó el mayor número de especies reproductoras (10 especies). Pelecanus occidentalis fue la especie más abundante con un total de 1 559 individuos, seguido de Fregata magnificens (fragata magnífica) y Sula nebouxii (bobo pata azul) con 1 526 y 1 100 individuos, respectivamente; aunque para estas dos últimas especies no hubo registros de reproducción. Las islas se encuentran bajo protección, pero se requiere realizar monitoreos para establecer el estado y tendencias de las poblaciones de aves, así como los efectos de las perturbaciones por actividades humanas y por las especies introducidas.

Kawasan Mangrove Center Kampung Blekok adalah salah satu kawasan mangrove yang menjadi tempat habitat burung air di Situbondo, Jawa Timur. Keanekaragaman dan aktivitas burung air memiliki peran secara ekologis terhadap ekosistem serta dapat menjadi indikator kondisi lahan basah. Tujuan dilaksanakan penelitian ini adalah untuk mengetahui keanekaragaman jenis burung air dan aktivitas burung air yang mendominasi di kawasan tersebut. Pengamatan terhadap keanekaragaman burung air menggunakan teknik pengambilan data metode titik hitung sedangkan pada pengamatan aktivitas Bubulcus ibis menggunakan metode scan sampling yang dilakukan pada pagi hari pukul 06.00-08.00 WIB dan pada sore hari pukul 15.00-17.00 WIB. Terdapat delapan spesies burung air penghuni tetap dan satu spesies burung air migran. Burung air penghuni tetap tersebut adalah spesies Bubulcus ibis, Ardeola speciosa, Butorides striatus, Egretta garzetta, Egretta alba, Nycticorax nycticorax, Ardea purpurea, dan Tringa hypoleucos, sedangkan burung air migran tersebut adalah Himantopus leucocephalus. Indeks keanekaragaman di titik 1 dan titik 2 pengamatan digolongkan rendah yaitu sebesar 0,90 dan indeks keseragaman digolongkan ke dalam tingkatan sedang yaitu sebesar 0,41 dan 0,43. Hal tersebut disebabkan oleh faktor adanya spesies yang mendominasi. Aktivitas burung Bubulcus ibis di titik 1 didominasi aktivitas menyelisik bulu dengan persentase sebesar 47,15%, sedangkan di titik 2 didominasi aktivitas terbang dengan persentase 55,24%. Hal tersebut dikarenakan faktor perbedaan karakteristik tempat kedua titik pengamatan dan faktor pengaruh manusia.

Full textAbstract:
Abstract Platyhelminths belonging to the family Clinostomidae (Digenea) have a worldwide distribution and are known to infect piscivorous birds through their intermediate hosts, usually fish species. In the present study, clinostome metacercariae were collected from fish hosts, including Channa punctata (Bloch 1793) (n = 25) and Trichogaster fasciata Bloch and Schneider 1801 (n = 25), from a freshwater system in India. The experimental infection of cattle egrets, Ardea (Bubulcus) ibis Linnaeus 1758, with some of the live metacercariae found in the present study was successful. Live adult parasites were obtained from the buccal cavity of the birds. Both metacercaria and adult specimens were subjected to molecular studies to obtain the sequences of 28S, ITS1, and ITS2 (nuclear rDNA) regions. The parasites were found to belong to three species, Clinostomum giganticum Agarwal 1959; C. piscidium Southwell and Prashad 1918; and Euclinostomum heterostomum (Rudolphi 1809). Phylogenetic analyses of the sequences obtained from the adults and metacercariae established a link between the metacercariae in the fish hosts and adults in the avian host, which is essential to elucidate their partial life cycle and specify morphological characteristics in the metacercarial stage.

Full textAbstract:
Abstract Background Previous cytogenetic studies show that the karyotypes of species in Ciconiiformes vary considerably, from 2n = 52 to 78. Their karyotypes include different numbers of small to minute bi-armed chromosomes that have evolved probably by fusions of two ancestral microchromosomes, besides macrochromosomes and dot-like microchromosomes. However, it is impossible to define the inter-species homologies of such small-sized bi-armed chromosomes based on chromosome morphology and banding characteristics. Although painting probes from the chicken (Gallus gallus, GGA) chromosomes 1–9 and Z have been widely used to investigate avian chromosome homologies, GGA microchromosome probes are rarely used in these studies because most GGA microchromosome probes generated by flow sorting often contain multiple GGA microchromosomes. In contrast, the stone curlew (Burhinus oedicnemus, BOE, Charadriiformes) has an atypical low diploid chromosome number (42) karyotype and only 4 pairs of dot-like microchromosomes; a set of chromosome-specific painting probes that cover all BOE chromosomes has been generated. To get a genome-wide view of evolutionary chromosomal rearrangements in different lineages of Ciconiiformes, we used BOE painting probes instead of GGA painting probes to analyze the karyotypes of three ciconiiform species belonging to two different families: the eastern grey heron (Ardea cinerea, ACI, 2n = 64, Ardeidae), the little egret (Egretta garzetta, EGA, 2n = 64, Ardeidae) and the crested ibis (Nipponia nippon, NNI, 2n = 68, Threskiornithidae). Results BOE painting probes display the same hybridization pattern on chromosomes of ACI and EGA, while a different hybridization pattern is observed on chromosomes of NNI. BOE autosome probes detected 21 conserved homologous segments and 5 fusions on the sixteen pairs of recognizable chromosomes of ACI and EGA, while 16 conserved homologous segments and 4 fusions were found on the twelve pairs of recognizable chromosomes of NNI. Only a portion of smaller bi-armed chromosomes in the karyotypes of the ciconiiform species could have evolved from fusions of ancestral microchromosomes. In particular BOE 5, which is the result of a fusion between two segments homologous to GGA 7 and 8 respectively, was retained also as either a single chromosome in ACI (ACI 5) and EGA (EGA 5) or had fused with a part of the BOE 10 equivalent in NNI (NNI 5). Conclusion Our painting results indicate that different chromosome rearrangements occur in different ciconiiform lineages. Some of the small-sized bi-armed chromosomes in ACI, EGA and NNI are derived from the fusions of two microchromosomes, indicating that microchromosome fusions play an important role in ciconiiform chromosome evolution. The fusion segment homologous to GGA 7 and 8 is a potential cytogenetic signature that unites Ardeidae and Threskiornithidae.

Full textAbstract:
Globally, many shorebirds, particularly the smaller migratory waders are declining, which can be attributed to multiple factors throughout their ranges. The Wilderness Lakes Complex in South Africa comprises two estuarine systems, that support diverse waterbird communities, including 17 abundant shorebirds. The study aimed to document long-term spatial and temporal patterns of abundance of shorebirds in the Wilderness Lakes Complex, and where possible identify potential causes for observed trends. The abundance of waterbirds on these wetlands was determined biannually from 1992 to 2019, with counts conducted from a boat following a standardised route. Historical abundance data from the 1980s were also used to describe long-term abundance changes. Ten shorebirds showed seasonal differences in abundances. Significant long-term decreases in abundance have occurred in seven shorebirds (Wood Sandpiper Tringa glareola, Marsh Sandpiper Tringa stagnatilis, Curlew Sandpiper Calidris ferruginea, Ruff Philomachus pugnax, Grey Heron Ardea cinerea, Greater Flamingo Phoenicopterus ruber, Black-winged Stilt Himantopus himantopus) and increases in three species (African Spoonbill Platalea alba, Little Egret Egretta garzetta, Glossy Ibis Plegadis falcinellus). Similar types of population changes occurred across multiple waterbodies and in different seasons. The similarity of shorebird abundance trends in spatially separated wetlands suggests either high interconnectivity of populations between wetlands systems and/or prominent drivers of change being broad scaled rather than system specific. Local reasons for changes potentially include the increasing spread of emergent macrophytes and resultant loss of open sandbanks, changing hydrodynamics, and alien fish proliferation, all likely changing food accessibility, as well as periodic high disturbance by waterbody users.Conservation implications: Changes in the abundances of several shorebirds, particularly small migratory waders, are substantial, with multiple likely local, regional and international drivers acting accumulatively. Recommended corrective actions include continuing involvement in the development and implementation of policies for waterbird conservation, and local management of emergent macrophytes, disturbance, and water level variability.
