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).

Also provided, when available, are recordings of the species' song and calls, selected from the collection in the Macaulay Library at the Cornell Lab of Ornithology and from other online sources, such as xeno-canto. Neotropical Birds Online Neotropical Birds Online is an online encyclopedia whose subject is the bird species that breed in the Neotropics. "Neotropical Birds Online" is patterned after "Birds of North America". Each account profiles a single species, and the accounts are published in the order in which they are completed. The project is
