The black oropendola (Psarocolius guatimozinus) is a species of bird in the family Icteridae (New World blackbirds).

The sexes are similar in appearance and are mainly black, with dark chestnut back, rump, part of the wing-coverts and crissum (the area around the cloaca).

There is a bluish bare patch on the cheek, edged with pink at its lowest extremity, and an orange-tipped, black beak.

Its range includes northwestern Colombia, as far east as the Magdalena River, and the extreme southeastern part of Panama, a total area of occupancy of about 108,000 km2 (41,700 sq mi).

[1][2] The habits of the black oropendola have been little studied but its diet probably includes insects, small vertebrates and fruit.
