>Cypsiurus parvus (African Palm Swift)

African Palm Swift

African Palm Swift
Conservation status

Least Concern (IUCN 3.1)
Scientific classification
Kingdom:Animalia
Phylum:Chordata
Class:Aves
Order:Apodiformes
Family:Apodidae
Genus:Cypsiurus
Species:C. parvus
Binomial name
Cypsiurus parvus
(Lichtenstein, 1823)
The African Palm Swift (Cypsiurus parvus) is a small swift. It is very similar to the Asian Palm Swift, Cypsiurus balasiensis, and was formerly considered to be the same species.
It is a common resident breeder in tropical Africa. The down and feather nest is glued to the underside of a palm leaf with saliva, which is also used to secure the usually two eggs. This is a fast flying bird of open country, which is strongly associated with Oil Palms.
This 16cm long species is mainly pale brown in colour. It has long swept-back wings that resemble a crescent or a boomerang. The body is slender, and the tail is long and deeply forked, although it is usually held closed. The call is a loud, shrill scream.
Sexes are similar, and young birds differ mainly in their shorter tails. Palm Swifts have very short legs which they use only for clinging to vertical surfaces, since swifts never settle voluntarily on the ground.
These swifts spend most of their lives in the air, living on the insects they catch in their beaks. Palm Swifts often feed near the ground. They drink on the wing.

The Asian Palm Swift (Cypsiurus balasiensis) is a small swift. It is very similar to the African Palm Swift, Cypsiurus parvus, and was formerly considered to be the same species.
It is a common resident breeder in tropical Asia from India to the Philippines. The down and feather nest is glued to the underside of a palm leaf with saliva, which is also used to secure the usually two or three eggs. This is a bird of open country and cultivation, which is strongly associated with Oil Palms.
This 13 cm long species is mainly pale brown in colour. It has long swept-back wings that resemble a crescent or a boomerang. The body is slender, and the tail is long and deeply forke, although it is usually held closed. The call is a loud shrill scream.
Sexes are similar, and young birds differ mainly their shorter tails. Asian Palm Swift has very short legs which it uses only for clinging to vertical surfaces, since swifts never settle voluntarily on the ground.

Cypsiurus is a genus of the swift family of birds.
There are two species
  • Asian Palm Swift, Cypsiurus balasiensis
  • African Palm Swift, Cypsiurus parvus
These very similar species were formerly considered to be conspecific.
They have mainly pale brown plumage and long swept-back wings that resemble a crescent or a boomerang. The body is slender, and the tail is long and deeply forked, although it is usually held closed. The sexes are similar, and young birds differ from adults mainly in their shorter tails. Palm Swifts have very short legs which they use only for clinging to vertical surfaces, since swifts never settle voluntarily on the ground.
These swifts spend most of their lives in the air, living on flying insects. Palm swifts often feed near the ground, and they drink on the wing.
