Habitat use of Amazonian birds varies by age and foraging guild along a disturbance gradient

Patterns of habitat use directly influence a species’ fitness, yet for many species an individual’s age can influence patterns of habitat use. However, in tropical rainforests, which host the greatest terrestrial species diversity, little is known about how age classes of different species use different adjacent habitats of varying quality. We use long term mistnet data from the Amazon rainforest to assess patterns of habitat use among adult, adolescent (teenage), and young understory birds in forest fragments, primary, and secondary forest at the Biological Dynamics of Forest Fragments Project in Brazil. Insectivore adults were most common in primary forest, adolescents were equally likely in primary and secondary forest, and all ages were the least common in forest fragments. In contrast to insectivores, frugivores and omnivores showed no differences among all three habitat types. Our results illustrate potential ideal despotic distributions among breeding populations of some guilds o..., , , # Habitat use of Amazonian birds varies by age and foraging guild along a disturbance gradient
