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
British Birds Rarities Committee existed in Scotland. In 2009, this species was removed, along with white-billed diver and cattle egret. Once removed, a species is classed as a "scarce migrant": "British Birds" publishes a separate annual report summarising the occurrence of these species, and the data is also presented on the Scarce Migrants website. In addition to parrot crossbill, four species, Cetti's warbler, little egret, long-tailed skua and Mediterranean gull, have become so common that they no longer qualify even as scarce migrants. The committee has ten voting members, a chairman (who may be one of the ten, or may be another, non-voting individual)
