Haemoproteus insects including mosquitoes, biting midges ("Culicoides"), louse flies ("Hippoboscidae") and tabanid flies ("Tabanidae"). Infection with this genus is sometimes known as pseudomalaria because of the parasites' similarities with "Plasmodium" species. Within the genus there are at least 173 species, 5 varieties and 1 subspecies. Of these over 140 occur in birds, 16 in reptiles and 3 in amphibia: 14 orders and 50 families of birds are represented. These include gamebirds ("Galliformes"), waterfowl ("Anseriformes"), raptors ("Accipitriformes", "Falconiformes", "Strigiformes"), pigeons and doves ("Columbiformes"), and perching birds or songbirds ("Passeriformes"). The first description of this genus was in 1890 by Kruse who described
Hawking (birds) for certain kinds of aerial insect as a food source seems to correlate with gregarious or colonial behavior versus territoriality. For birds that take advantage of swarming insects, which are by nature found in local concentrations, colonial breeding can be a successful strategy. An example is the cliff swallow of western North America. Its relative the barn swallow hunts larger, non-swarming insects, and is more solitary. Certain neotropical tyrant flycatchers will join mixed-species foraging flocks, as will some Asian drongos. Such flocks stir up flying insects, which can then be picked off in quick sallies. Hawking (birds) Hawking is a
