Breeding biology of Neotropical Accipitriformes: current knowledge and research priorities

open access: yesRevista Brasileira de Ornitologia, 2018
Despite the key role that knowledge on breeding biology of Accipitriformes plays in their management and conservation, survey of the state-of-the-art and of information gaps spanning the entire Neotropics has not been done since 1995. We provide an updated classification of current knowledge about breeding biology of Neotropical Accipitridae and define
