What is "campylorhamphus"

Campylorhamphus, the scythebills, are a bird genus in the woodcreeper subfamily ( Dendrocolaptinae). They are found in wooded habitats in South America and southern Central America, and all have very long, somewhat scythe-shaped bills.

The greater scythebill was formerly included in this genus, but it is closer to the scimitar-billed woodcreeper.
