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
The smallest swiftlet (9 cm), endemic to the Philippines. Dark grey-brown plumage. Aerial insectivore, foraging in small flocks over forest. Colonial cave nester. Despite being common, poorly studied due to the difficulty of distinguishing small, dark swiftlets in flight.
