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

Birds are popular characters in children's books, which are often handsomely illustrated. Beatrix Potter's
