Laughing Falcon feeds mainly on snakes (e.g. Parker et al. 2012), both terrestrial and arboreal, and even includes venomous species (e.g coral snakes, DuVal et al. 2006; rattlesnakes, Specht et al. 2008) in the diet. Will attack large snakes as well (Haverschmidt 1962). At one site in Guatemala, up to 20 species of snake were reported in the diet. In disturbed habitats, the diet is broader, incorporating rodents, birds, and even fish (Parker et al. 2012). At some sites in Brazil, forages for bats at cliffs (Sick 1993).
