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

The species are grouped into families such as "Of the Falcon", using the limited and conflicting scientific sources of the time. The families of land birds are further grouped into birds of prey, omnivorous birds, insectivorous birds, and granivorous birds, while the families of water birds are simply listed, with related families side by side. Each species entry begins on a new page; any spaces at the ends of entries are filled with tail-pieces, small, often humorous woodcuts of country life. "British Birds" remains in print, and has attracted the attention
