in the family Tyrannidae categorized the following moves as ways of taking insect prey: aerial hawking (i.e. flycatching), perch-to-ground sallying, ground feeding (chasing after insects on the ground), perch-to-water sallying, sally-gleaning (can involve an hover-gleaning or a rapid strike), and gleaning while perched. Some tyrant flycatchers, such as those that choose a prominent perch from which to hawk insects, have more of a tendency to return to the same perch after each sally, while others, particularly those of the forest interior, show less of this tendency. A similar pattern is seen in Great Britain, where there are but two flycatchers, the spotted flycatcher and the pied flycatcher. The spotted flycatcher is the specialist, and tends to return to the same perch after each sally. The pied flycatcher is more of a generalist, gleaning as well as flycatching, and changes perches often. Birds with the name "flycatcher" are not the only ones to engage in flycatching behavior. For example, Lewis's woodpecker feeds by flycatching. Some honeyeaters of Australasia employ hawking and gleaning as feeding tactics. Bee-eaters catch bees in a similar manner and return to the perch to remove the sting before consuming. Furthermore, many small owls take insect prey on the wing; examples include the western screech owl of North America and the brown boobook of Asia. Sustained-flight feeding Continuous aerial feeding is a different way of hawking insects. It requires long wings and skillful flying, as in nightjars, swallows, and swifts. Swifts are the masters of aerial feeding; several species spend virtually their entire lives in the air (some non-mating common swifts have spent as much as 10 months in the air without landing), and have come to rely on insects as their main source of food. Swallows, though visually similar to swifts but being unrelated to them, feed in a similar manner, but less continuously, as they don't glide as much and they stop to perch for a while between bouts of aerial feeding. This has to do with their prey: swifts fly higher in pursuit of smaller, lighter insects that are scattered by rising air currents, while swallows generally chase after medium-sized insects that are lower to the ground, such as flies. When swallows fly higher to go after smaller insects, they adjust their fight style to glide more, like a swift. Birds of the nightjar family employ a variety of moves for catching insects. The common
