Cloud-forest Pygmy-Owl

Cloud forest pygmy owls are small raptors in the genus Glaucidium (family Strigidae) inhabiting the montane cloud forests of Central and South America and Southeast Asia. These diminutive owls, typically 15–20 cm in length, are adapted to the cool, misty conditions of cloud forest zones at elevations from 1,500 to above 3,000 meters. Despite their small size, they are active and aggressive diurnal and crepuscular predators, hunting birds, lizards, large insects, and small mammals in the dense undergrowth and canopy of cloud forest. Many Glaucidium species possess distinctive false eye-spots on the back of the head — ocelli — that may deter attacks from behind by larger predators. Several cloud forest pygmy owl species have restricted ranges limited to individual Andean mountain ranges or Central American highland massifs, making them vulnerable to deforestation. The destruction and fragmentation of Andean and Central American cloud forests for coffee cultivation, timber extraction, and agricultural expansion have reduced suitable habitat for several Glaucidium species that depend on structurally complex, mature cloud forest.
