Telluraves Telluraves Telluraves (also called land birds or core landbirds) is a recently defined clade of birds with controversial content. Based on most recent genetic studies, the clade unites a variety of bird groups, including the australavians (passerines, parrots, seriamas, and falcons) as well as the afroavians (including the Accipitrimorphae – eagles, hawks, buzzards, vultures etc – owls and woodpeckers, among others). They appear to be the sister group of a newly defined clade centered on Aequornithes. Given that the most basal extant members of both Afroaves (Accipitrimorphae, Strigiformes) and Australaves (Cariamiformes, Falconiformes) are carnivorous, it has been suggested that the
Hawking (birds) tight spaces. Birds in more open settings that sally after larger insects like bees, such as kingbirds and bee-eaters, benefit from longer, more pointed wings, which are more efficient because they generate more lift and less drag. Swallows and swifts, which glide about in totally open spaces, have even longer wings. Another function of long, pointed wings is to enable these birds to turn quickly and smoothly in mid-glide. The wingtips create little vortices of air, within which the low air pressure creates additional lift on the wingtips. Furthermore, long, forked tails provide additional lift, stability, and steering ability, which
