Rather rare breeding resident inhabiting hills and foot hills. But can be occurred anywhere in the island. It flies as solitary birds or as small flocks, usually with other swifts and feeds entirely on flying insects like moths, beetles, etc. Alpine Swift select cracks and crevices of large rocky areas for roosting and nesting. Nesting period appears to be in the first half of the year. The nest is a shallow cup of straws, feathers, etc. stuck together with its own saliva and glued to wall of crevice or cave on cliff. It lays probably two or three eggs in it.
