The Palm Swift is a common and permanent resident in many parts of the Deccan, wherever there are plenty of palm trees, but where there are not, this bird is generally absent. Captain Butler saw a pair at Mount Aboo, but it must be very rare there, as no other observer has noticed it.
They nest twice in the year, in March and again in July; the nest, a tiny, watch-pocket-shaped cup, is made of saliva, incorporated with fine feathers, the down of plants, and such like kindred substances, and is fixed to the under surface of a bent palm leaf; the eggs, generally three in number, are miniatures of those of C. affinis, and average barely 0.71 in length by 0.46 in breadth.
