Puerto Rican Oriole Icterus portoricensis

A sleek inhabitant of wooded areas that ventures into gardens and parks searching for flowers and fruit; prefers areas with palms. The adult is distinctively all black except for its yellow vent, rump, and shoulders. No similar species occur within its range. Immatures are yellow to yellow-orange and resemble immature Baltimore Orioles, but have thicker and blacker bill and lack the white wingbars seen on Baltimore Orioles. Full song is fluid series of whistled upslurred and down-slurred notes. Calls include a buzzy “zzwhi” and an emphatic “tchu.”
