Corvida

Corvida is an infraorder of passerine birds. It includes the lyrebirds and scrub-birds. It is sister to Climacterida, Meliphagida, Pomatostomida, and Passerida.

Corvida may have evolved in New Guinea/Australia; their diversity increased in the Eocene or Oligocene in the New Guinea archipelago, and eventually migrated to Asia and the rest of the world (Jønsson, et al. 2011; Aggerbeck, et al. 2014).

Distribution
Members of Corvida are cosmopolitan except for southern South America, some islands and Antarctica; they are found from Australia and New Zealand to the United States and Canada, to South America, Africa, Europe and Asia.

Endemism
Mohouidae is only found in New Zealand. Whistlers are endemic to Australasia (from India to Australia and New Guinea).
