Brazilian Merganser ducklings are born in captivity PDF Imprimir E-mail


Conhecer mais sobre aspectos da biologia e do comportamento do pato-mergulhão. Estes são alguns dos objetivos da nova campanha de captura e marcação da espécie realizada entre os dias 7 e 10 de outubro na região da Serra da Canastra pelos pesquisadores do Instituto Terra Brasilis.
Durante a campanha, foram capturados e anilhados dez indivíduos, dos quais dois foram marcados com rádios transmissores para posteriormente serem monitorados. Além disso, foram coletadas amostras de sangue para análise genética e realizados os procedimentos padrão, como pesagem, sexagem e avaliação das condições dos indivíduos.
“A campanha de captura e marcação é realizada anualmente, desde 2008, pelo Terra Brasilis, o que tem possibilitado o acúmulo de dados sobre a biologia do pato-mergulhão, contribuindo também com os estudos de genética que são essenciais para traçar estratégias para a conservação da espécie”, explica Lívia Lins, coordenadora do Programa Pato-mergulhão.

Eight eggs were collected to compose the species' captivity program

An important tool for the conservation of the Brazilian Merganser, the Captivity Program of the Brazilian Merganser, recorded a great breakthrough. Eight eggs of the species were collected and taken to the Zooparque Itatiba/SP, to compose the Program, which is coordinated by Brazil’s Chico Mendes Institute of Biodiversity Conservation - ICMBio. Four eggs were collected in Jalapão/TO and four in the region of Patrocínio/MG.

The ducklings were born and are developing well, growing and being fed adequately. The expectation is that they reproduce in the next years, strengthening the captivity program. 

These new individuals join the two which already have been in the Zooparque Itatiba since 2014, besides the other two that have been at the Criadouro Científico Poços de Caldas, since 2011, when the captivity program began, starting from the eggs collected in Serra da Canastra. 

"By increasing the Brazilian Merganser's population in captivity, it is possible to plan the introduction of the individuals in nature. This is one of the most important objectives of the captivity program, which is aimed at contributing to decreasing the degree of threat of extinction of the species", explains Lívia Lins, coordinator of the Brazilian Merganser's Program.
