Quantifying habitat quality is dependent on measuring a site's relative contribution to
population growth rate. This is challenging for studies of waterbirds, whose high mobility can …

Abstract In the Nearctic-Neotropical migration system, ca. 250 landbirds mobilize between
breeding and wintering grounds each year. Several migratory species face multiple …

The Blackpoll Warbler (Setophaga striata) is a rapidly declining Nearctic-Neotropical
migratory bird that breeds across the boreal forest of North America and migrates to South …

Neotropical forests contain the most diverse avian community globally, which includes 241
migratory species. Conversion of natural habitats to agriculture and the intensification of …

Neotropical migratory birds exhibit surprising variation in wintering home range size. Such
variability reflects the fact that, within the same species, space-use strategies can range from …
