Campylorhamphus

Campylorhamphus is a genus of birds in the ovenbird family Furnariidae. The genus was formerly considered to contain three species, but is now generally recognized to contain only one. The genus is native to South America, where it is found in humid evergreen forests. Campylorhamphus species are insectivorous, feeding on a variety of insects, spiders, and other small invertebrates. They are typically found foraging in the understory of forests, where they probe bark and leaf litter with their long, curved bills.

The single species currently recognized in the genus is the Scimitar-billed Woodcreeper (Campylorhamphus trochilirostris). This species is characterized by its long, decurved bill, which is used for probing for insects in tree bark and on branches. The Scimitar-billed Woodcreeper is found in the Amazon Basin, where it inhabits humid evergreen forests. It is a relatively common species, but its cryptic behavior and preference for dense vegetation can make it difficult to observe.

The taxonomic history of Campylorhamphus is complex, with several species having been previously assigned to the genus. However, recent molecular and morphological studies have led to a revision of the genus's composition. The remaining species, the Scimitar-billed Woodcreeper, is a distinctive bird with a highly specialized bill morphology, reflecting its unique foraging niche. Further research may continue to refine our understanding of this genus and its relationship to other woodcreeper taxa.
