Bird of prey "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 Turnton. Louis Pierre Veillot used additional ranks: order, tribe, family, genus, species. Birds of prey (order Accipitres) were divided into diurnal and nocturnal tribes; the owls remained monogeneric (family Ægolii, genus "Strix"), whilst the diurnal raptors were divided into three families: Vulturini, Gypaëti, and Accipitrini. Thus Veillot's families were similar to the Linnaean genera, with the difference that shrikes were no longer included amongst the birds of prey. In addition
Prey detection all of these senses in pinpointing their prey, while others may depend mainly or entirely on a single one. Detection methods may also be divided into direct detection of the prey organism itself, and indirect clues, such as the smell of its urine. Visual predators may form what is termed a search image of certain prey. Predators need not locate their host directly: Kestrels for instance are able to detect the faeces and urine of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example. This adaptation is essential in prey
