Any number of aerial-foraging insectivorous birds like swifts, swallows or
woodswallows; dippers, auks and penguins, which actively pursue prey under
water; hawks like the African harrier-hawks and neotropical Crane Hawk that
actively search for lizards in holes in trees; large gulls and skuas that
pursue and catch smaller seabirds on the wing; etc...
