Puerto Rico has 349 species of birds, approximately 120 of which are resident breeders. There are 18 endemic species, many accidentals, and 42 known introductions. Puerto Rican avifauna, as a group, has received more attention from the conservation community than other faunal groups. According to the IUCN Red Data List, 14 of the endemic bird species are classified as Species of Least Concern. The remaining four are classified as Critically Endangered (Puerto Rican Parrot), Endangered (Yellow-shouldered Blackbird; Puerto Rican Nightjar) and Vulnerable (Elfin-woods Warbler).
The following bird images were taken by Erick Xavier Pérez Guzmán, who is a Ph.D. student in medical microbiology at the University of Puerto Rico School of Medicine. Many thanks to biologist Carol Skinner, Ph. D., who contributed to this and our Puerto Rico destination page.
