Formerly, the genus only contained the plantain-eaters, but in 2021, go-away-birds were merged into the genus. Britton, P.L., ed. (1980). Birds of East Africa: 375.

The bare-faced go-away-bird is a noisy and restless species, that moves about singly or in groups. [7] Food and feeding [ edit ] The grey go-away-bird ( Crinifer concolor), also known as grey lourie, grey loerie, or kwêvoël, is a bold and common bird of the southern Afrotropics. They are present in arid to moist, open woodlands and thorn savanna, especially near surface water. [2] They regularly form groups and parties that forage in tree tops, or dust bathe on the ground. Especially when disturbed, they make their presence known by their characteristically loud and nasal "kweh" or "go-way" calls, [3] with the last syllable typically a descending drawl. [4] Within their range, their unique combination of colour, appearance and habits precludes confusion with other bird species.a b c d Irwin, M. P. S. (1981). The Birds of Zimbabwe.

The bare-faced go-away-bird was described in 1842 by the German naturalist Eduard Rüppell based on a specimen collected in Abyssinia (Ethiopia). He coined the binomial name Chizærhis personata. [2] [3] The specific epithet is from Latin personatus meaning "masked" (from persona meaning "mask"). [4] The bare-faced go-away-bird was formerly placed in the genus Corythaixoides but based on a molecular phylogenetic study published in 2020, it was moved to the genus Crinifer.

Fruit are obtained from plants in the genera Ficus, Viscum, Loranthus, Diospyros, Lannea, Ziziphus, Salvadora [11] and Flueggea, among others. They also feed on fruit of exotic invasives like seringa, and disperse their seeds. [2] Breeding [ edit ] Though their flight is rather slow and laboured, [4] they can cover long distances. [10] Once in the open tree tops however, they can display the agility which is associated with the Musophagidae, as they run along tree limbs and jump from branch to branch. [4] They can form groups and parties numbering even 20 to 30 that move about in search of fruit and insects near the tree tops.Scientific: Chizaerhis concolor, Coliphimus concolor, Corythaix concolor, Corythaixoides concolor, Corythaixoides concolor concolor, Crinifer concolor a b c d e f Johnson, D.
