Aerial feeder
A bird which obtains most or all of its food in flight. Although some types of raptor feed in this way, the term normally refers to those birds which spend their time hawking insects, namely the nightjars (family Caprimulgidae), the swifts (family Apodidae), the swallows (family Hirundinidae) and the flycatchers (family Muscicapidae).From Peter Weaver's Birdwatcher's Dictionary
