Apus balstoni
The Malagasy Black Swift (Apus balstoni) is a medium-sized, highly aerial bird, measuring approximately 14.5-15.5 cm in length with a robust, streamlined body built for sustained flight. Its plumage is uniformly dark sooty-brown to black, often appearing pure black against the sky, with only a faint, often indistinct, paler patch on the chin and throat that is rarely visible in the field. Distinctive field marks include its long, scythe-like pointed wings and a moderately forked tail, typical...
This swift primarily inhabits areas with suitable vertical structures for nesting and roosting, including rocky cliffs, large boulders, caves, and sometimes man-made structures like bridges or abandoned buildings. It forages widely over diverse landscapes, from open country and forests to savanna...
The diet of the Malagasy Black Swift consists entirely of flying insects, often referred to as 'aerial plankton,' including Hymenoptera (ants, bees, wasps), Coleoptera (beetles), Hemiptera (bugs), and Diptera (flies). They capture their prey efficiently while on the wing.
Malagasy Black Swifts are exclusively aerial for most of their lives, only landing to nest or roost. They are colonial birds, forming large aggregations at breeding and roosting sites in inaccessible cliff faces or cave systems. Their daily activity patterns involve continuous, high-speed flight,...

It can be found across the entire island, though observations are particularly frequent in the western, central, and southern regions w...
