Natal dispersal and philopatry of Chimango Caracaras (Milvago chimango) in suburban, rural and natural habitats, determined by band recovery and re-sighting data

Emu - Austral Ornithology, 2018
ABSTRACTNatal dispersal is a process whereby birds move from their birthplace to the site of their first attempt at reproduction. This process has strong implications for the dynamics and genetic structure of populations. However, studies on the dispersal of neotropical birds of prey are scarce.

Prevalence of Pathogens in Free-Living Adult Chimango Caracaras (Milvago chimango) in Three Areas with Different Levels of Urbanization in the Pampas Ecoregion, Argentina

Journal of Raptor Research
. Urbanization can adversely impact animal populations through factors such as loss of natural habitat, introduction of nonnative competitors and predators, pollution, and increased exposure to pathogens.

Cognitive flexibility in a generalist raptor: a comparative analysis along an urbanization gradient

Behavioral Ecology
In this study, we analyzed the variation in cognitive flexibility in the Chimango Caracara (Milvago chimango), across areas with different levels of urbanization.

Assessing Knowledge of the Caracaras: Compiling Information, Identifying Knowledge Gaps, and Recommendations for Future Research

The Journal of raptor research
. Because information availability and management are essential components of wildlife conservation, we sought to compile literature published since 1900 on the caracaras, a group of nine extant species, eight of which occur only in Central America and ...
