Cassin's spinetail is a species of swift in the family Apodidae. It is found throughout the African tropical rainforest.
Region
West and Central African tropical rainforest
Typical Environment
Primarily inhabits lowland evergreen rainforest, frequently hunting above the canopy, along forest edges, and over rivers and clearings. It tolerates secondary growth and selectively logged areas so long as substantial canopy remains. The species is seldom found far from forest, though it will range over adjacent open areas while feeding. Roost sites are typically sheltered structures within forested landscapes.
Altitude Range
Sea level to 1500 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
Cassin's spinetail is a small forest swift that spends most of its life on the wing, snatching insects in fast, agile flight. Its stiff, spiny tail tips help it brace against surfaces when roosting. It often forms loose flocks over forest clearings and rivers and may join mixed groups of other swifts. Vocalizations are thin, high-pitched twitters given while circling high above the canopy.
Temperament
social and active
Flight Pattern
fast, agile flight with rapid wingbeats; occasional brief glides
Social Behavior
Typically seen in small groups or loose flocks, often associating with other swift species over forest openings. Breeding pairs nest in concealed sites within forested habitats, using simple structures of feathers and saliva. Roosting occurs in sheltered crevices or cavities where the tail spines aid bracing.
Migratory Pattern
Resident
Song Description
Gives high, thin twitters and short trills while in flight, often exchanged between birds circling high overhead. Calls carry faintly and can be hard to localize against canopy noise.
