“…In turn, for T. amaurochalinus the occurrence of an overlap of migrant individuals or populations over the resident ones is possible, and the occurrence of T. subalaris was only observed during its migratory passage in summer. Although not the ultimate aim of this paper, we agree with the works of Galina & Gimenes (2006) and Catian & Aranda (2009), who draw attention to the relevance of urban-forested ecosystems in the maintenance of several bird species. There is a frequent use of these habitats not only by the resident species but also by migratory birds which use the sites as resting areas when in migration, obtaining food, shelter and reproductive sites.…”

Seasonal segregation among syntopic species can be viewed as one of the available strategies for coexistence, reducing competitive process. The present work therefore aimed to interpret the assemblage structures comprising birds of the genus Turdus (Turdidae), through the analysis of seasonal variation in the species occurrence in a forest remnant located in the southcenter State of Paraná. Mist-netting was employed twice a month for capturing birds, totalling an annual effort of 7488 h.m². The frequency of occurrence, constancy and class of species dominance was determined, together with the parameters generally used in studies of ecological communities (richness, abundance, diversity and evenness). A total of 162 individuals were captured, representing five species. Turdus rufiventris was the most constant and frequent species. Turdus amaurochalinus and Turdus leucomelas were captured with variable constancies and frequencies along the seasons. Turdus amaurochalinus was also very common and may present an overlapping process between migrant and non-migrant individuals during spring. Turdus albicolis was considered accessory, whereas Turdus subalaris was only registered during the reproductive period. Hence, it was possible to observe that seasonal modifications occurred both in the frequency of occurrence and in the constancy and dominance of species. These results indicated the possibility of a lower use of the environment during the breeding season, as well as the presence of a higher number of individuals in summer and increased abundance of Turdus rufiventris and T. leucomelas during autumn and winter.

“…Assim, de modo geral os dados foram satisfatoriamente obtidos. Resultados similares constam em outros estudos com aves urbanas (CATIAN et al, 2011;BLAMIRES, 2013;ALBADO;BLAMIRES, 2019;FERREIRA et al, 2020;CARDOSO et al, 2022;VALADÃO et al, 2022).…”

A avifauna de lagos urbanos no estado de Goiás é pouco conhecida. Assim, este estudo analisou as aves em dois lagos inseridos na malha urbana de um município na Microrregião de Anicuns, interior de Goiás. Os dados foram coletados mensalmente entre outubro de 2020 a setembro de 2021, totalizando 12 visitas em cada lago, entre 6h30 e 10h30 (48h atividade/lago e 96h/atividade total). Percorrer o perímetro de cada lago foi o método empregado para registro das espécies. Um total de 105 espécies, pertencentes a 41 famílias, foi encontrado nos dois lagos estudados. De modo geral, predominaram as famílias Traupidae, Tyrannidae e Psittacidae, para o total de dados e cada lago separadamente. Pandion haliaetus (Linnaeus, 1758), espécie “visitante sazonal não-reprodutivo do Norte (VI(N))”, e Amazona aestiva (Linnaeus, 1758), espécie “quase ameaçada (NT)”, foram registradas no Lago “Parque Josias Alves” na periferia urbana, demonstrando assim a relevância conservacionista desta área, que também apresentou maior riqueza em relação ao Lago “Parque Bela Vista” no centro da malha urbana. O estimador de Chao2 e as curvas de distribuição assintóticas demonstraram que a riqueza foi satisfatoriamente obtida, para o total de dados e cada lago analisado separadamente. Com relação às categorias de ocorrência, para ambos os lagos predominaram as espécies Prováveis Residentes e Residentes. Recomendamos mais estudos nestes lagos, para esclarecer outros aspectos ecológicos em suas avifaunas. Pesquisas futuras, tanto em São Luís dos Montes Belos quanto em outros municípios circunvizinhos certamente ampliarão o conhecimento avifaunístico ao longo desta paisagem no interior goiano.
