These small falcons like to perch on the tops of dead snags. Males are considerably smaller than females and have a somewhat different head shape. This is a male. Notice the ear-like projection on the side of his head. Bat Falcons eat birds, flying insects and bats which they capture in mid-air. The kill in these photos is a bird (toes are visible), but too many feathers have been plucked for me to identify. Any suggestions? Two (HBW) or three (Clements) subspecies are recognized with petoensis ranging from Mexico to Ecuador. One or two darker races are found in South America, east of the Andes. The scientific name F. albigularis has been applied to this species in the past.
