The rest of the under parts, including the under-wing coverts, are white, finely and clearly barred with black or dark gray. The upper breast is a darker gray. The primary remiges are dark brownish-gray with off-white bars on the inner webs. Subspecies, M. Voice: The barred forest falcon's "advertising call" is "a somewhat dog-like, monotonous yapping, "keyak", "ark" or similar". Another call is a "bouncing-ball series..."cah cah cah-cah-cah", or similar". Neighboring males spar when one gives "a rapid, swelling chitter and the other a rapid clucking".
