How to identify it
The slaty-backed forest falcon is 40 to 45 cm (16 to 18 in) long. Males weigh about 420 g (15 oz) and females about 500 to 556 g (18 to 20 oz). Its wingspan is 65 to 71 cm (26 to 28 in). Adults have slate gray upperparts, and are darker on the crown and lighter on the cheeks. Their throats and underparts are white to cream, and plain but for a few dark feather shafts making streaks. Their tail is dark slate gray with a white tip and three narrow white bars that often are indistinct. Their iris is yellowish brown to dark brown, its cere greenish yellow, and its legs and feet bright yellow. Voice: The slaty-backed forest falcon's primary vocalization is a "chanting series of 8-13 nasal, shouting kiiih or kaaah notes". It also makes a "high-pitched eek-eek-eek...", apparently to provoke small passerines to mob it so it can catch one.
