Beautiful forest-falcon, typically very difficult to see. Has a gray head and back, bare red facial skin, and white underparts with gray bars on the breast. Note the single broad white bar on the upper tail. Found in dense humid forest. Has a distinctive song, usually given at dawn, typically a slow series of single low-pitched “uk uk uk uk....” notes. Can be confused with Barred Forest-Falcon, but adult Barred Forest-Falcons have bare yellow facial skin and heavily barred underparts with three narrow white tail bars.
