Oruguero Gris

The grey cuckooshrike (Ceblepyris caesius) is a species of bird in the cuckooshrike family Campephagidae. It is a medium-sized forest bird, with grey to blue-grey plumage and large black eyes. There are two subspecies that occur in forest patches of southern and central Africa respectively. == Taxonomy == The grey cuckooshrike belongs to the family Campephagidae of the old world songbirds. There are almost 90 species within Campephagidae that occur in Africa, Asia and Australasia. Ceblepyris caesia is often considered to be part of a superspecies with the white-breasted cuckooshrike (Ceblepyris pectoralis); which looks somewhat similar apart from the striking white underparts compared to C. caesia's grey underparts. The grey cuckooshrike is also found at higher elevation than its white-breasted counterpart. A 2010 genetic analysis confirmed the two species as each other's closest relatives, with their common ancestor diverging from the ancestor of Grauer's cuckooshrike. "Grey cuckooshrike" has been designated the official name by the International Ornithologists' Union (IOC). The species is also commonly referred to as the mountain grey cuckooshrike and the African grey cuckooshrike. South African names include usinga in Pirie Forest, umsimpofu in Elliotdale and around the mouth of the Mthatha River, and umswinkobe in eastern Pondoland.…
