Recurve-billed bushbird

The recurve-billed bushbird (Clytoctantes alixii) is an Endangered species of Thamnophilid antbird that inhabits dense stands of secondary vegetation at the northern end of the Andes in Colombia and Venezuela. It is named for its extraordinary bill, which curves upwards. Until 2007, the bird was almost unknown in life and apart from earlier specimens it had only been seen in life once at an army ant swarm in Colombia in 1965.

The recurve-billed bushbird is 16 to 17 cm (6.3 to 6.7 in) long. It is rather stocky with a short tail. Its large bill is pale horn; it is laterally compressed and the mandible is upturned. The sexes have different plumage. Adult males are generally dark gray, with a white patch between their shoulders. Their lores, throat, and the center of their upper breast are black. Their wing coverts have small black spots and their flight feathers are brownish black. Adult females have a dark rufous-brown crown, back, and rump. Their wings and tail are blackish with pale rufous tips on the wing coverts. Their underparts are reddish brown that is darker on their flanks and undertail coverts. Subadult males are dark yellowish and blackish brown; their forehead, sides of the head, and throat are reddish yellow-brown and their wing coverts have white dots.
