The Apolo cotinga or palkachupa cotinga (Phibalura boliviana) is a species of passerine bird in the family Cotingidae. It is a member of the genus Phibalura.
The Apolo cotinga was collected in Bolivia in 1902 and in 1930 described as a subspecies of the swallow-tailed cotinga (Phibalura flavirostris boliviana).[2] The bird was rediscovered in 2000 (after 98 years without any records). It is restricted to the vicinity of Apolo in Bolivia.[3] The population is threatened by habitat loss and therefore listed as an endangered species.
Phibalura boliviana is treated as a separate species because of eye color, more curved bill, color of feet and tarsi, longer tail and different vocabulary. The Apolo cotinga is sedentary, while the swallow-tailed cotinga is partially migratory, often moving to lower elevations during the south hemisphere winter.[4][5]
