Range and Habitat

Colima Pygmy-Owl: Endemic resident of western Mexico. Found from central Sonora south to Morelos and Guerrero, from sea level to 1,500 meters in elevation. Prefers dry, tropical thorny forests. Also occurs in coffee plantations and mixed pine-oak forest.

Breeding and Nesting

Colima Pygmy-Owl: Although the breeding behavior of this species is very poorly documented, it is probably similar to that of other pygmy-owl species whereby two or more white eggs are laid in an old woodpecker hole or other natural tree cavity, and are incubated by the female for 28 days.

Foraging and Feeding

Colima Pygmy-Owl: Eats arthropods, small lizards, and small birds. It forages by waiting on a perch in the day and then swooping to the ground or vegetation to catch prey with its talons.

Vocalization

Colima Pygmy-Owl: Song is a series of 2-24 short, high-pitched hoots followed by a pause, then another series of hoots. Usually the number of hoots increases, "hoo-hoo, hoo-hoo-hoo, hoo-hoo-hoo-hoo".
