About These Birds
Black-billed Scythebill
The Black-billed Scythebill is a large woodcreeper of Atlantic Forest in southeastern Brazil and adjacent Argentina, remarkable for its extremely long, strongly decurved bill used to probe bark crevices, bromeliads, and palm frond bases for insects. Its plumage is streaked rufous-brown overall. It forages by creeping up tree trunks and branches in humid forest interior.
