It has also been recently observed catching and imprisoning small birds, removing their flight feathers and feeding them, sometimes days later, to their young. This is unique among bird species. Occasionally, it was observed as feeding on bats.

''Alauda'' 83(2): 149-150. This falcon is unique in that it is one of the few species that breeds during early autumn, feeding its chicks with other migratory birds that are in abundance that period. It is also one of the few falcon species that creates breeding colonies. It nests on coastal cliffs, laying up to four eggs.
