Resumo: The modification of landscapes by anthropic action, mainly due to urbanization, exerts strong pressure on birds. Public parks and other green areas offer favorable conditions for birds in cities throughout the year. Nannopterum brasilianus (Gmelin, 1789), the Neotropic cormorant, is one of the most frequent and abundant piscivorous water birds in urban parks, rivers and reserves. The present study aimed to describe the behavioral repertoire of N. brasilianus and evaluated possible behavioral changes in the dry and rainy seasons, in an urban area in Uberlândia (MG). The study was conducted in Sabiá Municipal Park, from December 2013 to November 2014, totaling 184 hours of observation. The fixed-point sampling method was used, in four ponds in the park. Observations were made in the morning, using the focal animal and ad libitum (record of all occurrences) techniques. In all, 164 records of the species were obtained. The behavioral repertoire included 15 behavioral acts, notably perching and preening. Some behaviors varied between the seasons (?² = 62.05, df = 14, p <0.001), including flock flight and perching on the pond bank, which were displayed more in the rainy season.

Parques públicos e outras áreas verdes oferecem condições favoráveis para a permanência de aves nas cidades ao longo do ano. A espécie Nannopterum brasilianus (Gmelin, 1789), biguá, é uma das aves aquáticas piscívoras mais frequentes e abundantes em parques urbanos, rios e reservas. O objetivo deste trabalho foi descrever o repertório comportamental de Nannopterum brasilianus, avaliando possíveis mudanças comportamentais nas estações seca e chuvosa, em uma área urbana de Uberlândia (MG). O estudo foi conduzido no Parque Municipal do Sabiá, no período de dezembro de 2013 a novembro de 2014, totalizando 184 h de observação. Utilizou-se o método de amostragem de ponto fixo, em quatro lagoas do Parque. As observações foram realizadas no período da manhã, sendo utilizadas as técnicas animal focal e observação de todos os registros (ad libitum). Ao todo, foram obtidos 164 registros da espécie. O repertório comportamental incluiu 15 atos comportamentais, com destaque para repouso-poleiro e preening. Os comportamentos mostraram variações entre as estações do ano (?² = 62,05; df = 14; p < 0,001), sendo vôo-grupo e repouso-margem mais exibidos na estação chuvosa. Universidade Federal de Santa Catarina2019-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n3p8710.5007/2175-7925.2019v32n3p87Biotemas; v. 32 n. 3 (2019); 87-952175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n3p87/40667Copyright (c) 2019 Dayana Nascimento Carvalho, Liliane Martins de Oliveira, Oswaldo Marçal Juniorinfo:eu-repo/semantics/openAccessCarvalho, Dayana NascimentoOliveira, Liliane Martins deJúnior, Oswaldo Marçal2019-08-21T09:21:41Zoai:periodicos.ufsc.br:article/58590Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2019-08-21T09:21:41Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
