Atronanus fuliginosus
The Forest Swallow (Atronanus fuliginosus) is a captivating passerine known for its striking deep forest specialization, a contrast to many open-country swallow species. Measuring approximately 14-16 cm in length with a wingspan of 28-32 cm and weighing 15-20 grams, its plumage is a glossy, iridescent blue-black across its upperparts, wings, and deeply forked tail, transitioning to a clean white on the belly and undertail coverts. A key identification mark is the distinct, albeit often subtle...
This species primarily inhabits mature, deciduous and mixed-conifer forests, often favoring areas near clearings, rivers, or large lakes for foraging. It is typically found at elevations ranging from 200 to 1500 meters during the breeding season.
Exclusively insectivorous, primarily consuming small, soft-bodied flying insects such as mosquitoes, gnats, flies, and small beetles, caught almost entirely on the wing.
Forest Swallows are diurnal, active from dawn until dusk, often seen darting through the understory or just above the canopy. They roost communally in large tree cavities, dense evergreen thickets, or occasionally abandoned woodpecker holes. Foraging involves acrobatic, high-speed aerial pursuits...
The breeding range of the Forest Swallow spans the mature deciduous and mixed forests of eastern North America, from southern Canada (Ontario, Quebec, Maritimes) south through the Appalachian Mountains to northern Georgia, and west into the Great Lakes region (Michigan, Wisconsin, Minnesota).

Near Threatened
- The Forest Swallow possesses specialized wing feather structures that allow for remarkably silent flight through dense forest, a unique adaptation among swallows. - Despite being a forest specialist, it undertakes one of the longest migratory journeys relative to its body size among North Ameri...
