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
Bird scarer idea of visually scaring birds. This method doesn't work so well with all species, considering that some species frequently perch on scarecrows. Many species of bird are also naturally afraid of predators such as birds of prey. "Hawk kites" are designed to fly from poles in the wind and hover above the field to be protected. They are shaped to match the silhouette of a bird of prey. The Helikite bird scarer is a lighter-than-air combination of a helium balloon and a kite. Helikites fly up to 200vft in the air with or without wind. Although they do not look
