About These Birds
African Swift
A medium-sized swift (16-17 cm) found across sub-Saharan Africa. Dark sooty-brown plumage, darker than Pallid Swift. Aerial insectivore, foraging high over varied habitats from forests to savannas. Breeds on cliffs and buildings. Resident or partial migrant within Africa.
Pygmy Swiftlet
