He placed all birds of prey into a single order, Accipitres, subdividing this into four genera: Vultur (vultures), Falco (eagles, hawks, falcons, etc.), Strix (owls), and Lanius (shrikes). This approach was followed by subsequent authors such as Gmelin, Latham and Turton.
Many well-known birds such as hawks, eagles, kites, harriers and Old World vultures are included in this group. The osprey is usually placed in a separate family ( Pandionidae ), as is the secretary bird ( Sagittariidae ), and the New World vultures are also usually now regarded as a separate family or order.
The Accipitriformes (/ æ k ˌ s ɪ p ɪ t r ɪ ˈ f ɔːr m iː z /; from Latin accipiter 'hawk' and formes 'having the form of') are an order of birds that includes most of the diurnal birds of prey, including hawks, eagles, vultures, and kites, but not falcons.
However, at least two species have successfully been used, the Eurasian eagle-owl and the great horned owl. [10] Successful training of owls is much different from the training of hawks and falcons, as they are hearing- rather than sight-oriented. (Owls can only see black and white, and are long-sighted.)
The order Falconiformes (/ f æ l ˈ k ɒ n ɪ ˌ f ɔːr m iː z /) is represented by the extant family Falconidae (falcons and caracaras) and a handful of enigmatic Paleogene species. . Traditionally, the other bird of prey families Cathartidae (New World vultures and condors), Sagittariidae (secretarybird), Pandionidae (ospreys), Accipitridae (hawks) were classified in Falconifo
A vulture is a bird of prey that scavenges on carrion. There are 23 extant species of vulture (including condors ). [ 2 ] Old World vultures include 16 living species native to Europe , Africa , and Asia ; New World vultures are restricted to North and South America and consist of seven identified species, all belonging to the Cathartidae family .
Pellets are found in different locations, depending on the species. In general, these are roosting and nesting sites: for most hawks and owls, under coniferous trees; for barn owls, at the bases of cliffs or in barns and silos; for yet other species of owls, at their burrows or in marsh and field grasses.

As with hawks and owls, falcons exhibit sexual dimorphism, with the females typically larger than the males, thus allowing a wider range of prey species. [10] As is the case with many birds of prey, falcons have exceptional powers of vision; the visual acuity of one species has been measured at 2.6 times that of human eyes. [11]
