Buckley's Forest Falcon is a little-recorded falcon of lowland forest in western Amazonia. It is more often detected by its voice than seen, especially near dawn.
One field description reported a dark gray back and wings, white tail bars, a broad white collar, and pale underparts. That bird was thought to be a young male, so the pattern may not represent every age or sex.
This forest falcon is recorded more often by voice than by sight. Calls are concentrated before dawn, with fewer records near dusk, and vocal activity can change with the weather.
