Pale-billed Woodpecker (Campephilus guatemalensis) This male and female were interacting in a tall tree in Manuel Antonio (Costa Rica). They seemed to talk to each other incessantly the whole time I observed them. They're a noble-looking woodpecker, with their striking red crest and white bill, much like the nearly extinct Ivory Bill (Campephilus principalis).
This is the characteristic (and diagnostic) "double drum" of the Pale-billed Woodpecker (Campephilus guatemalensis), usually done every 30 seconds or so. This bird was signalling in the river bottom at El Gavilan, near Puerto Viejo de Sarapiqui (Costa Rica), 6/20/99.
