testakteja

Testakteja, also known as Testacteja, is a genus of small to medium-sized birds belonging to the family Furnariidae, which includes ovenbirds, woodcreepers, and tyrant flycatchers. The genus is native to South America, with species ranging from southern Mexico to northern Argentina. Testakteja birds are typically found in dense forests and are known for their distinctive, loud calls that are often used to communicate with other members of their species.

The genus Testakteja was first described by the German ornithologist Jean Cabanis in 1847. It is named after the Greek words "testa," meaning "head," and "akte," meaning "sharp," referring to the distinctive, sharp crest on the head of some species. The genus includes several species, with the most well-known being the Rufous-capped Antthrush (Testakteja rufa). This species is characterized by its rufous cap, grayish-brown upperparts, and white underparts. It is found in the eastern slopes of the Andes in Colombia and Venezuela.

Testakteja birds are insectivorous, feeding on a variety of insects and other small invertebrates. They are typically solitary birds, although they may form loose flocks during the non-breeding season. The breeding season varies depending on the species, but it generally occurs during the wet season. Nesting is typically done in a tree cavity, and the female lays 2-3 eggs. Both parents take turns incubating the eggs and caring for the young.
