Effects of anthropogenic activities on habitats and species communities
and populations are complex and vary across species depending on their
ecological traits. Movement ecology may provide important insights into
species´ responses to habitat structures and quality. We investigated how
movement behavior across a human-modified landscape depends on species
identity and species traits, with particular focus on habitat
specialization, feeding guilds and dispersal behavior. We tracked 34
individuals of nine Afrotropical bird species during three years in an
anthropogenic riparian landscape of East Africa. We investigated whether
species’ functional traits predicted their habitat use and movement
behavior better than species´ identities. Our results indicate that
habitat specialists mainly occur in dense riparian thickets, while habitat
generalists do occur in agricultural land. Home-ranges of omnivorous
habitat generalists are larger than of frugivorous and insectivorous
generalists and omnivorous and insectivorous specialists. Movement speed
was highest in settlement areas for all species, with activity peaks
during morning and afternoon for habitat specialists. Our results reveal
that functional traits and species identity provide complementary insights
into responses of organisms to habitat structures and habitat quality. Habitat use and movement
behavior of Afrotropical birdsThe data include
movement data collected by radio tracking of nine Afrotropical bird
species differing in habitat specialization, feeding preference and
dispersal ability. The first spreadsheet includes data concerning
birds' habitat use, the second spreadsheet includes home-range sizes
and the third spreadsheet includes movement speed within the different
habitats and for the different times of the day.Habitat use and movement
