Full textA second presumed correlate of behavioural flexibility, taxonomic variation in the use of urbanised and other anthropogenically-modified habitats, shows a consistent pattern in four geographical zones (Great Britain, North America, Australia and New Guinea), as well as a qualitative association with the relative size of the forebrain. There is no linear correlation, however, between urbanisation rate per taxon and either forebrain size or innovation rate, suggesting that other variables like diet, tameness and neophilia may have to be quantified at finer taxonomic levels in future studies of opportunism in habitat use.

A urbanização altera a composição e a diversidade das comunidades bióticas, por esse motivo pesquisas ecológicas têm sido realizadas nas cidades com o objetivo de reconhecer seus impactos. As aves, consideradas bioindicadores, têm sido intensamente estudadas em áreas urbanas. O objetivo deste estudo foi avaliar a riqueza e a abundância da avifauna na área urbana de Bauru (SP), bem como verificar como diferentes coberturas vegetais podem interferir na comunidade de aves. A avifauna foi amostrada entre dezembro de 2014 e novembro de 2015 em quatro áreas, sendo três condomínios residenciais e um campus universitário. As observações ocorreram mensalmente em cada uma das áreas, sendo uma hora no período matutino e uma hora no período vespertino. O método utilizado foi o transecto linear com duração de 60 minutos, totalizando 96 horas de observação. Em todas as áreas foi realizada a caracterização da cobertura vegetal arbórea como número de espécies e de indivíduos utilizando amostras de vegetação paralelas aos transectos. Foi observado que a riqueza de aves aumentou com a riqueza da vegetação. Além disso, as áreas mais urbanizadas e com menor diversidade vegetal estiveram relacionadas com alta abundancia e poucas espécies de aves. Sugerindo que uma maior riqueza da cobertura arbórea, mesmo em áreas centrais das cidades, pode auxiliar na presença da avifauna.

The objective of this study was to evaluate the richness and abundance of avifauna in the urban area of Bauru, state of São Paulo (SP), Brazil, as well as verify how different vegetation covers may interfere with the bird community. The avifauna was sampled between December 2014 and November 2015 in four areas: three residential condominiums and a university campus. The observations were monthly held in each of the areas, one hour in the morning and one hour in the afternoon. The method used was linear transect with a duration of 60 minutes, totaling 96 hours of observation. In all areas, it was carried out the characterization of arboreal vegetation cover, as for the number of species and individuals, using parallel vegetation samples to transects. It was observed that the richness of birds increased with the richness of vegetation. In addition, more urbanized areas and with less plant diversity were related to high abundance and a few species of birds. Suggesting that the richness of arboreal covering, even in central areas of cities, may assist in the presence of avifauna.

O processo de urbanização promove a modificação no uso da terra e torna as áreas urbanas em um complexo mosaico de ambientes naturais e antrópicos. A maracanã- pequena (Diopsittaca nobilis - Psittacidae) teve sua população drasticamente reduzida no estado de São Paulo, todavia apresenta diversas populações recentemente estabelecidas em municípios da região sudeste do país, entre os quais, São Paulo. O estudo teve como objetivo avaliar a distribuição, uso de habitat e parâmetros ecológicos de D. nobilis no município de São Paulo, buscando compreender o estabelecimento desta população e o uso do ambiente pela espécie. Foram realizados levantamentos bibliográficos e de dados primários, além de consultas a instituições e especialistas. Quatro campanhas de amostragem foram executadas entre setembro/2015 e julho/2016, em 15 distritos do município, empregando-se o método de “taxa de encontro” em trajetos pré-selecionados. O estudo indica que D. nobilis foi introduzida no município a partir de alguns eventos de soltura, o primeiro deles entre 1987-88, corroborando o Parque Ecológico do Tietê como local e estimando-se um número inicial desta população em 30 a 50 indivíduos. O número inicial de indivíduos, a repetição dos eventos de soltura, realizada com bandos que poderiam ter até 15 indivíduos, e recursos fornecidos pela arborização viária disponível, bem como a suplementação de alimentos no período inicial (soltura branda) devem ter contribuído para o estabelecimento desta população. A distribuição da espécie concentra-se na região central do município, assim como avaliado para o período inicial de estabelecimento, verificando-se progressiva diminuição dos registros à medida em que se afasta do centro. A extensão de ocorrência foi avaliada em 807 km² para São Paulo, chegando a 1074 km² quando considerados registros para a Região Metropolitana. A população de D. nobilis foi avaliada, por meio de censo com contagem simultânea de indivíduos em dormitórios, entre 456 a 524 indivíduos, podendo chegar a 594 indivíduos, ou mais, se consideradas áreas de potencial dormitório ou eventuais dormitórios desconhecidos. A espécie se apresentou como o segundo psitacídeo mais comum na cidade, atrás apenas de Brotogeris tirica. Os bandos registrados variaram entre 1 a 38 indivíduos, com prevalência de casais e bandos com até seis aves, sendo verificada variação circanual no tamanho de bandos, possivelmente refletindo o período reprodutivo da espécie, apontado como de setembro a janeiro. Identificou-se o consumo de frutos, sementes e flores de 12 famílias de plantas, de 22 espécies, predominantemente exóticas. A associação de D. nobilis a palmeiras, verificada para pernoite e sugerida para alimentação e reprodução, deve ser melhor investigada. A espécie distribui-se fundamentalmente pela área urbana, verificando-se sua ausência na região rural do extremo sul do município. A avaliação de uso de habitat indica associação da espécie a Áreas Verdes urbanas, sendo que a população de D. nobilis parece se configurar como uma exploradora do ambiente urbano. Recomenda-se a continuação dos estudos sobre a espécie em áreas urbanas e áreas em que foi introduzida, dando sequência à investigação dos fatores que influenciam a distribuição da espécie em área urbana, mas também abrangendo biologia reprodutiva e tendência populacional.
Urbanization process promotes land use change, creating a complex mosaic of natural and anthropic environments. While the Red-shouldered-macaw (Diopsittaca nobilis – Psittacidae) has had its population severely reduced in the São Paulo state, nowadays it has established several populations in cities in the Brazilian Southeast Region, including the São Paulo city. The present research aimed to evaluate the distribution, habitat use and ecological parameters of the D. nobilis population in São Paulo city, in order to understand the establishment of this species and its environmental use. The research encompassed bibliographic search and personal contact with institutes and experts, besides primary data collection. Field work was conducted between September/2015 and July/2016, in 15 municipal districts, using “encounter rate” method in pre-selected tracks. The research indicates D. nobilis was introduced in the city by some release events, beginning in 1987-88, with initial population size estimated around 30 to 50 individuals. Our study corroborates Tiete Ecological Park as the place where the species was introduced. Some facts such as the initial number of released birds; repeated releases events of groups which could have until 15 individuals, considering this is a gregarious species; and resources provided by urban trees available and soft release may have contributed to the population establishment. The species distribution covers especially the central region of the city, as it was checked for establishment period, noticing a decrease in number of registers as it increases the distance to the central area. The extent of occurrence was gauged in 807 km² in São Paulo city, reaching 1074 km² considering registers available in the Greater São Paulo. D. nobilis population size, evaluated by simultaneous counts of communal roost sites, encompassed between 456 and 524 individuals, which could reach 594 individuals, or even more, considering potential roost areas or unknown roost sites. The species was the second most common parrot in the city, after the most common Brotogeris tirica. Flocks of D. nobilis had between 1 to 38 individuals, and couples and groups of up to six birds prevailed. The flock size presented an annual fluctuation, possibly in response to the reproductive period of the species – between September to January, as indicated by this research. We identify the species feeding of fruits, seeds and flowers of 12 plant family, comprising 22 species, most of them exotic. Association between D. nobilis and palm trees was verified for roosting and it was suggested for feeding and nesting, but it must be better investigated. The species distribution comprised the urban area of the city, being absent in the rural area in the south region of São Paulo. The evaluation of the D. nobilis habitat use indicates an association between the species and urban green areas. D. nobilis population could be classified as an urban exploiter. Further studies are recommended about this species in urban areas and in areas with introduced populations, in order to continue the investigation about factors which influence the distribution of this species in urban areas, but also involving reproductive biology and population trends.

Full textGrönytor i städer är satt under hög press på grund av ökande befolkningstäthet vilket leder till att fler människor behöver dela på samma mängd urban grönyta. Detta fenomen ökar kraven på förvaltningen av grönytor då de behöver generera fler nyttigheter och mera värde. Ett sätt att öka dessa värden skulle kunna vara att använda sig av indikatorer för ekosystemtjänster inom ett förvaltningssystem där flera förvaltare verkar. Är det möjligt att indikatorer för ekosystemtjänster kan underlätta samarbetet mellan olika förvaltare och därigenom öka värdet av en grönyta? Den här masteruppsatsen hade målet att identifiera indikatorer för ekosystemtjänster genererade av en grönyta och sedan inkorporera dem i en förvaltningsmetod som ökar samverkan mellan förvaltare. Studien syftade till att tydliggöra om användandet av ekosystemtjänstindikatorer kan underlätta samarbetet av mellan olika förvaltare för att förbättra förvaltningen av en grönyta. Det första steget för att åstadkomma detta var att låta förvaltarna uttrycka vilka värden och nyttigheter de vill att grönytan skulle skapa. Dessa värden och nyttigheter formulerades som målvariabler vilka länkades till de ekosystemtjänster som grönytan bedömdes generera. Genom en litteraturstudie identifierades indikatorer som kunde indikera de ekosystemtjänster som genererades vid grönytan. Indikatorerna kvantifierades och inkorporerades in i ett redan existerande förvaltningssystem. Studien resulterade i två identifierade indikatorer och i utvecklandet av ett förvaltningssystem som underlättar samverkan genom användandet av indikatorer. Fåglar identifierade som en indikator på grund av att fåglar indikerade samma ekosystemtjänster som genereras på grönytan. Fåglar valdes också för att det var möjligt att kvantifiera fåglarna vid grönytan. Villkorlig sittplats var den andra indikatorn och den har möjligheten att fungera som en kontrollindikator eftersom den kan beskrivas som en manifestation av de ekosystemtjänster som genereras på grönytan. Sedan så utvecklas även ett förvaltningssystem där indikatorerna inkorporerades. Förvaltningssystemet hade målet att underlätta samverkan mellan de olika förvaltarna med hjälp av indikatorerna. Sammanfattningsvis så bedöms det att indikatorer för ekosystemtjänster har potentialen att användas i ett förvaltningssystem och därigenom kunna bidra till att öka värdet av grönytan.

Full textThe urbanization is one of the anthropic activities with the highest growth rate in the world. Due to this reason, ecological research are conducted in the cities with the goal of recognizing its impacts, using birds as one of the tools to assess the environmental diagnosis. Therefore, the present study assessed the samples by point counts method, which is broadly used for bird census in many environments. Three issues that might affect the sampling of the birds by using this method were analyzed: 1) the habitat where the sampling is performed, observing the urban elements presented in the city; 2) the period of point count duration spent in each sample; 3) the potential factors which disturb the birds detectability, as urban noise and presence of curious citizens who can talk to the researcher in the point count. The research area was stratified from the amount of tree canopies in the selected suburbs, where 90 sample units were selected. In these units, the presence of urban elements, the richness, the number of birds contacts, the noise and the presence of conversations were quantified. The results showed that the number of species and contacts can be benefited from the tree canopy area, while build up areas and impermeable grounds may harm the number of species, although the contact number is harmed only by the impermeable grounds. The number of observed species did not differ significantly after nine minutes of sample period, however the number of contacts kept increasing, demonstrating a repeated counting birds after this interval. The species richness was significantly different between the samples collected in dry and wet seasons. As the urban noise increased, a lower number of species and birds contacts was acknowledged. The incidence of conversation performed by curious people was low, not being able to harm the sample collection. The results suggest that: the bird survey inside the cities by point counts should consider the composition of environment, since the richness and the number of birds contacts can vary according to the presence of different elements; the time of interval should not exceed nine minutes; when possible, different annual seasons should be used for sampling, since differences may be found among them; places and moments for the sampling should be chosen with a low noise. Finally, the point counts method was considered efficient for the sampling of urban birds, provided that such care are considered.

Full textCette étude visait à comprendre la diversité et la composition des communautés d'oiseaux et d'insectes présentes dans des champs abandonnés par rapport à l'intensité d'urbanisation des terres adjacentes dans la région de Montréal. Les sept taxons d'insectes choisis étaient: les papillons et les hespéries (Lepidoptera); Carabidae (Coleoptera); Dolichopodidae, Syrphidae, Sphaeroceridae, Chloropidae (Diptera); Apoidea (Hymenoptera). Au total, 386 oiseaux nicheurs représentant 42 espèces, ainsi que 2255 oiseaux migrateurs représentant 31 espèces ont été répertoriés. Plus de 7000 spécimens d'insectes comprenant 264 espèces ont été identifiés. Les résultats indiquent que la diversité des champs abandonnés reste stable, malgré des différences dans l'urbanisation des terres adjacentes, du moins dans les groupes étudiés. Toutefois, il y avait quelques exceptions : la diversité des papillons et des hespéries ainsi que l'abondance des syrphes étaient plus élevées dans les sites suburbains comparé aux sites periurbains; de plus, les oiseaux nicheurs étaient plus abondants dans les sites ruraux que les sites suburbains. Les assemblages d'oiseaux nicheurs dans les sites suburbains démontraient le plus grand degré de similitude les uns par rapport aux autres. Malgré ces résultats, le patron global indique que la diversité et les assemblages d'oiseaux et d'insectes dans les champs abandonnés diffèrent peu malgré des alentours suburbains, périurbains ou ruraux. Chloropidae serait le seul taxon influencé par l'urbanisation des terrains adjacents, particulièrement par la quantité de terrains résidentiels et industriels et d'espaces verts. Étant donné ces variations, aucun des taxons choisis n'a pu être utile en tant qu'espèce indicatrice des patrons de diversité des autres taxons; cependant, quelques corrélations significatives ont été établies entre certains taxons.

Resumo: O processo de urbanização no Brasil aumenta rapidamente e as áreas verdes fornecem refúgio para a fauna local, na qual as aves são o elemento mais evidente. Aves são agentes importantes de dispersão e polinização, controle de pragas, além de ciclagem de nutrientes e adubação do solo, exercendo diversos serviços ambientais. Embora essas funções possam ser vistas como tendo pouca importância no ambiente urbano, aves apresentam grande mobilidade, o que significa que suas funções podem ser transportadas de uma área verde para outra. Estudamos a história natural das aves em um parque urbano em Campinas, São Paulo. Alimentação, reprodução e repouso foram os focos deste estudo, além de outras atividades como higiene e conforto. As atividades alimentares que observamos seguem, em linhas gerais, o que está relatado na literatura sobre aves brasileiras. Entretanto, observamos alguns fenômenos não relatados ou pouco conhecidos Associações alimentares de aves piscívoras seguindo lontras em atividade de caça não estavam relatadas para América do Sul. Disputa por área de caça entre fêmeas de biguatinga Anhinga anhinga foi outra novidade relacionada à atividade alimentar, assim como a predação de um bivalve asiático invasor por aves aquáticas. A inclusão de uma categoria de presa (répteis) na dieta do sabiá Turdus leucomelas também representou uma novidade. As atividades reprodutivas que observamos no parque também seguem, em linhas gerais, as informações disponíveis na literatura sobre aves brasileiras. Todavia, observamos eventos pouco conhecidos ou não relatados na literatura. A corte do urubu Coragyps atratus está relatada para a América do Norte apenas. Também pouco conhecida é a disputa territorial "simbólica" entre fêmeas do pica-pau Colaptes melanochloros, comportamento relatado para machos de outras espécies. Outra novidade foi a pressão de predação pelo lagarto Salvator merianae em ninhos de aves que nidificam no chão ou em vegetação próxima a margem de lagoa. Atividades de higiene e conforto são bem conhecidas e ilustradas na literatura e acreditamos que não tenhamos observado algum comportamento de higiene e conforto que não esteja relatado, ainda que de passagem, para as aves brasileiras. Estudos sobre história natural de aves proporcionam um conhecimento mais adequado das relações entre as aves, o ambiente urbano e a população humana. Em parques e áreas verdes, as aves representam uma parcela de lazer para a população urbana. O número de observadores de aves aumenta no Brasil e, paralelamente, há uma valorização da conservação ambiental. Portanto, estudos em parques urbanos resultam em conhecimento sobre a avifauna, além de valorizar as áreas verdes e popularizar o conhecimento sobre as aves e a sua importância biológica
Abstract: The urbanization process in Brazil is quickly changing the landscape and so called green areas provide refuge for the local fauna, of which birds are the most conspicuous part. Birds are important agents of plant dispersal and pollination, pest control, as well as nutrient cycling and soil fertilizing, which result in ecosystem services. Although these functions may be viewed as having little or no importance in the urban landscape, birds are highly mobile and their functions may connect several green areas. We studied the natural history of birds in an urban park in Campinas, São Paulo, Southeastern Brazil. We focused on feeding, reproducing, and resting, besides preening and comfort activities. In general, feeding activities we observed followed what is published about Brazilian birds. However, we observed a few little known or until recently unpublished events. Feeding associations of piscivorous birds following foraging otters were unreported for South America. Contests for hunting area between females of the darter Anhinga anhinga was another novelty related to feeding activity, as well as the predation of an Asiatic invasive clam by water birds. Predation of reptiles by the thrush Turdus leucomelas was also a novelty. In general, reproductive activities we observed followed what is published for Brazilian birds. However, we observed a few little known or unpublished behaviors. For example the courtship of the vulture Coragyps atratus is reported for the North America only. Also little known is the territorial "symbolic" contest between females of the woodpecker Colaptes melanochloros, a behavior reported for males of other species. Another novelty was the predation pressure on birds that nest on the ground or bank vegetation by the large lizard Salvator merianae. Preening and comfort behaviors are well known and illustrated in literature and we believe that we did not record any behavior that is not reported in the literature on Brazilian birds, even if en passant. Studies on natural history of birds provide a better knowledge on the relationships between the birds, the urban landscape, and the human population. In urban parks and green areas, birds are part of leisure activities for urban people. The number of birdwatchers is increasing in Brazil and, at the same time, there is a growing awareness of environment conservation among people who are in contact with nature. Therefore, studies on natural history of birds in urban parks and other green areas result in knowledge of the bird fauna, besides increasing the intrinsic value of these environments and making available details of the life of birds and their biological significance

Resumo: O processo de urbanização promove a modificação no uso da terra e torna as áreas urbanas em um complexo mosaico de ambientes naturais e antrópicos. A maracanã- pequena (Diopsittaca nobilis - Psittacidae) teve sua população drasticamente reduzida no estado de São Paulo, todavia apresenta diversas populações recentemente estabelecidas em municípios da região sudeste do país, entre os quais, São Paulo. O estudo teve como objetivo avaliar a distribuição, uso de habitat e parâmetros ecológicos de D. nobilis no município de São Paulo, buscando compreender o estabelecimento desta população e o uso do ambiente pela espécie. Foram realizados levantamentos bibliográficos e de dados primários, além de consultas a instituições e especialistas. Quatro campanhas de amostragem foram executadas entre setembro/2015 e julho/2016, em 15 distritos do município, empregando-se o método de "taxa de encontro" em trajetos pré-selecionados. O estudo indica que D. nobilis foi introduzida no município a partir de alguns eventos de soltura, o primeiro deles entre 1987-88, corroborando o Parque Ecológico do Tietê como local e estimando-se um número inicial desta população em 30 a 50 indivíduos. O número inicial de indivíduos, a repetição dos eventos de soltura, realizada com bandos que poderiam ter até 15 indivíduos, e recursos fornecidos pela arborização viária disponível, bem como a suplementação de alimentos no período inicial (soltura branda) devem ter contribuído para o estabelecimento desta população ...

Abstract: Urbanization process promotes land use change, creating a complex mosaic of natural and anthropic environments. While the Red-shouldered-macaw (Diopsittaca nobilis - Psittacidae) has had its population severely reduced in the São Paulo state, nowadays it has established several populations in cities in the Brazilian Southeast Region, including the São Paulo city. The present research aimed to evaluate the distribution, habitat use and ecological parameters of the D. nobilis population in São Paulo city, in order to understand the establishment of this species and its environmental use. The research encompassed bibliographic search and personal contact with institutes and experts, besides primary data collection. Field work was conducted between September/2015 and July/2016, in 15 municipal districts, using "encounter rate" method in pre-selected tracks. The research indicates D. nobilis was introduced in the city by some release events, beginning in 1987-88, with initial population size estimated around 30 to 50 individuals. Our study corroborates Tiete Ecological Park as the place where the species was introduced. Some facts such as the initial number of released birds; repeated releases events of groups which could have until 15 individuals, considering this is a gregarious species; and resources provided by urban trees available and soft release may have contributed to the population establishment. The species distribution covers especially the central region of the city, as it was checked for establishment period, noticing a decrease in number of registers as it increases the distance to the central area. The extent of occurrence was gauged in 807 km² in São Paulo city, reaching 1074 km² considering registers available in the Greater São Paulo. D. nobilis population size, evaluated by simultaneous counts of communal roost sites, ... (Complete abstract electronic access below)
