Surveys of Forest Birds on Puerto Rico 2015

摘要

BackgroundThe island of Puerto Rico supports a diverse assemblage of breeding birds, including 16 endemic species (), and provides critical wintering habitat for many North American migratory birds (). Despite being a hotspot of avian biodiversity, spatially extensive data on the distribution and abundance of birds on the island are scarce. Breeding-bird assemblages were sampled by the North American Breeding Bird Survey from 1997–2007 (), but comparable primary data are not available for bird assemblages present during the boreal winter.
