Description

The mountain pygmy owl (Glaucidium gnoma) is a small owl from Central America. It is considered a distinct species by some authorities, including the International Ornithologists' Union. Others, including the American Ornithological Society, consider to be a subspecies of northern pygmy owl. If considered conspecific, the scientific name G. gnoma is usurped by the northern pygmy owl. The Northern Mountain Pygmy Owls’ habitats range from coniferous forests to deciduous bottomlands, and despite its large geographic distribution, “it is one of the least studied owls on the continent” (Holt & Peterson 2000). Its diet consists of small birds and mammals, and it has a reputation of being a fierce hunter. This species of owl will nest in natural cavities and in ones created by woodpeckers (Holt & Peterson 2000). In a study conducting research on Northern Mountain Pygmy Owls preferred habitats in the Rocky Mountains, it was discovered to prefer large diverse forests with trees near a stream because it offered protection from predators and camouflage for ambush attacks (Jageman et. al. 2018).

Feeding Habits
Northern Pygmy-owl primarily feed on a variety of small birds, small mammals, insects, and reptiles. Their prey includes hummingbirds, chickadees, warblers, sparrows, shrews, moles, chipmunks, beetles, butterflies, crickets, dragonflies, lizards, and skinks. Notably, they sometimes hunt prey larger than themselves, such as Northern Bobwhite and California Quail.
Habitat
Northern Pygmy-owl primarily inhabits open coniferous or mixed woods, including wooded canyons. These birds prefer a range of forest environments—from deciduous woodlands along streams to high-elevation conifer forests near the timberline. They are adaptable to various vegetation types, including cottonwood, aspen, and mixed-conifer forests. At higher altitudes, northern Pygmy-owl can be found in fir and spruce forests, while in more tropical regions, they reside in pine-oak and scrub forests, as well as highland pine and cloud forests. During winter, northern Pygmy-owl descends to lower elevations and may venture into urban areas, notably seeking prey at bird feeders.
Nest Behavior
Northern Pygmy-owl's nesting period aligns with spring, laying eggs directly on cavity debris. Parental care involves both partners, with the female primarily incubating and the male providing food.
Nest Characteristics
Northern Pygmy-owl utilizes pre-existing tree cavities, often at mid-to-high elevations, with no additional construction. Debris like wood chips or decomposing leaves serves as the nest base, occasionally lined with feathers or bark strips.

Behavior

Northern Pygmy-owl exhibit diurnal tendencies, predominantly hunting by daylight. They maneuver through the air with a distinct flight pattern resembling woodpeckers. During the breeding season, they display monogamous behaviors, with males courting females via a resonant tooting call at nest entrances. While females are exclusive incubators, males provision both female and offspring. Their existence is threatened by larger predatory birds and certain mammals. Interestingly, smaller birds often boldly mob northern Pygmy-owl, despite being their typical prey, perhaps dissuaded by deceptive eyespots on northern Pygmy-owl's nape.

Species Status

Not globally threatened.
