The bay-vented cotinga (Doliornis sclateri) is a species of bird in the family Cotingidae. It is endemic to Peru. == Taxonomy and systematics == A few late twentieth century authors merged genus Doliornis into Ampelion but multiple studies since then have confirmed its separation. The bay-vented cotinga is monotypic. It shares genus Doliornis with the chestnut-bellied cotinga (D. remseni) and the two form a superspecies. == Description == The bay-vented cotinga is 20 to 21.5 cm (7.9 to 8.5 in) long and weighs 53 to 69 g (1.9 to 2.4 oz).

Their upper back is dark grayish that becomes browner on the rump and tail. Their wings are grayish brown. Their face and throat are a paler gray than their upperparts. Their breast and belly are brown; in unworn plumage their breast has buff bars. Their undertail coverts are rufous chestnut. Adult females have a dark gray crown with dusky streaks and a duller red crest. Their back and uppertail coverts are paler than the male's. Both sexes have a gray iris, a black maxilla, a blue-gray mandible…
