African Palm Swift

Cypsiurus parvus, commonly known as the African Palm Swift, is an classical contributor to the avifauna of Sub-Saharan Africa. Found in the order Apodiformes, family Apodidae, and genus Cypsiurus, these humming-bird relatives in the beginning feed on insects, beetles, termites and spiders (Moreau 1941). The distribution of this species depends on the front end of address trees, as the supportive fronds are the fasts favoured cuddleing site (Moreau 1941). The swift builds its nest on the upper edge of the leaf employ feathers, cotton fibres and copious amounts of tongue for adhesion (Moreau 1941). The nest is a perpendicular platform, forcing the swift to glue its eggs to the nest with saliva to get word their safety (Hails and Turner 1982). African palm swifts exhibit a number of unique adaptations in their pull through behaviour. Moreau (1941) explored swift breeding biology; particularly foc utilise on how fervently they consort to their eggs during brooding, an d how often nestlings were fed. To characterize this behaviour, Moreau used data from over 700 hours of close observation at nests containing both(prenominal) eggs and young, at a site in Tanzania. Moreau (1941) report that swifts are pretty inconsistent in their brooding behaviour, with periods of coverage often followed by hours of neglect.

Furthermore, Moreau (1941) found that parents share the responsibility of victuals the fledglings, with meals typically delivered deep refine one hour of their deviance from the roost in the morning, and some(prenominal) times during the last hour of daylight. collins (1965) characterized the plumage of African Palm Swifts, describing ! the development of feathers from naked hatchling, to down covered nestling. Collins (1965) reported that by the 6th day of development the plucked bird had transformed into a hoi polloi of white pubescent feathers. Collins (1965) found that the semi-plumes of swifts likely set a thermoregulatory purpose, as nestlings are frequently left unattended for hours at a time.
