Ptyonoprogne concolor
The Dusky Crag Martin, Ptyonoprogne concolor, is a small, agile passerine bird belonging to the swallow family (Hirundinidae). Measuring approximately 13 cm (5.1 in) in length and weighing a mere 10-12 grams, it is characterized by its uniform dusky brown plumage, a slightly paler throat and underparts, and distinctive white patches on its square tail, most visible in flight. These pale spots are a crucial field mark for separating it from similar martins. Taxonomically, it is closely related...
Found primarily in rocky areas, gorges, and cliffs, the Dusky Crag Martin also readily adapts to human-made structures such as bridges, dams, and large buildings. It occurs from lowlands up to moderate elevations, typically below 2,000-3,000 meters.
This species is an obligate aerial insectivore, feeding exclusively on flying insects. It captures these prey items on the wing, often making swift, acrobatic maneuvers.
Dusky Crag Martins are diurnal birds, spending much of their day hawking for insects in graceful, buoyant flight. They often forage solitarily or in small, loose flocks, particularly outside the breeding season, sometimes joining mixed-species feeding frenzies with other swallows. Roosting typica...
