The black-faced grosbeak (Caryothraustes poliogaster) is a species of bird in the family Cardinalidae, the cardinals, grosbeaks, and “tanager” allies. it is found from Mexico to Panama. The black-faced grosbeak was formally described in 1847 with the binomial Pitylus poliogaster. According to most taxonomic systems it now shares the genus Caryothraustes with the yellow-green grosbeak (C. canadensis). However, BirdLife International's Handbook of the Birds of the World (HBW) also includes the crimson-collared grosbeak and the red-and-black grosbeak in the genus. The other systems assign them to the genus Periporphyrus.
The black-faced grosbeak is about 14 to 22 cm (5.5 to 8.7 in) long; five individuals weighed an average of 35 g (1.2 oz). The sexes have the same plumage. Adults of the nominate subspecies are black on their lores, face, and throat. Their forecrown is yellow and the rest of their head is yellow with an olive tinge. Their upper back, wings, and tail are yellowish olive-green. Their... Wikipedia →
