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
Boeing Bird of Prey Development of the Bird of Prey began in 1992 by McDonnell Douglas's Phantom Works division for special projects, at Area 51. The aircraft's name is a reference to the Klingon Bird of Prey warship from the "Star Trek" television series. Phantom Works later became part of Boeing Integrated Defense Systems after the Boeing–McDonnell Douglas merger in 1997. The first flight was in 1996, and 39 more flights were performed through the program's conclusion in 1999. The Bird of Prey was designed to prevent shadows and is believed to have been used to test active camouflage, which would involve its surfaces
