Hirundo atrocaerulea
The Blue Swallow (Hirundo atrocaerulea) is a strikingly beautiful yet critically endangered passerine, renowned for its iridescent, deep cobalt-blue plumage that can appear almost black in dim light. Measuring approximately 23-25 cm in length, it is distinguished by extraordinarily elongated outer tail streamers, especially in males, which can reach up to 15 cm. These distinct streamers, along with its rich coloration and preference for specific high-altitude grasslands, serve as key identifi...
This species primarily inhabits high-altitude, moist, undulating grasslands, often near wetlands or permanent water sources, typically found at elevations between 1200 and 2200 meters during the breeding season.

Outside the breeding season, they are gregarious, forming communal roosts, sometimes in reedbeds, but during breeding, males establish and defend breeding territories. Courtship involves e...
The breeding range of the Blue Swallow is highly fragmented and restricted to specific high-altitude grasslands in southeastern Africa. Key breeding strongholds are found in eastern South Africa (Mpumalanga, KwaZulu-Natal), Eswatini, and historically in western Zimbabwe, typically at elevations o...
