Open encyclopedia reference
The white-tailed swallow (Hirundo megaensis) is a small swallow belonging to the family Hirundinidae and is endemic to Oromia, Ethiopia. It is commonly referred to as "Benson's swallow" after the ornithologist Constantine Walter Benson, who described the species. This small bird is classified as a vulnerable species by the International Union for Conservation of Nature (IUCN), as there is a progressive declination of the species which now consists of less than 10,000 adult individuals worldwide. It has a surprisingly small range for a swallow, as it is wholly dependent on a cooler "bubble" surrounding its small range, likely for proper breeding success. It is one of the most threatened bird species by climate change and a massive range reduction is projected in the future.
