The Grey go-away-bird (Crinifer concolor) is a bold and common turaco of the southern Afrotropics. They regularly form groups that forage in tree tops, or dust bathe on the ground. Within their range, their unique combination of color, appearance, and habits precludes confusion with other bird species.
These birds have an almost uniform smoky-grey plumage with long tails and a wispy, back-swept crest of some 6 to 7 cm in length. The crest can be raised almost vertically when excited. The strong, decurved beak is black and the gape and tongue strikingly pink. The plumage is darkest grey on the chin and throat, and palest around the eyes and on the belly. The breast plumage is washed slightly olive.
Grey go-away-birds are native to southern Angola, southern DRC, Zambia, southern Tanzania, Malawi, Mozambique, Namibia, Botswana, Zimbabwe, South Africa, and Eswatini. They inhabit arid to moist, and relatively open savanna woodlands, especially where Acacia trees are present. They frequent the edges of miombo woodland and occur commonly along water courses, dry riparian forests, and in Acacia woodland on alluvium. They also frequent farms, suburban gardens, and parks. They require water and disperse along tributaries of desert rivers when water flows. They have no regular migrations but wander about irregularly in search of food and water.
Grey go-away-birds are social and can form groups and parties numbering even 20-30 individuals. They spend the days moving about in search of food near the treetops. Their flight is rather slow and labored, but they can cover long distances. Once in the open treetops, however, these birds can run along tree limbs and jump from branch to branch. Especially when disturbed, they make their presence known by their characteristically loud and nasal 'kweh' or 'go-way' calls.
Grey go-away-birds are monogamous and form strong pairs. The breeding season is July to August in Angola, April to November in Malawi, August to September in Zambia, Sept and December to April in Namibia, and all months in Zimbabwe and South Africa. These birds construct a flimsy nest platform from fairly thin, and often thorny sticks. It has the appearance of a substantial dove's nest, and their almost round, white eggs can be seen from below. Usually, 3 eggs are laid in a nest that is placed at the center of an isolated tree. The incubation period lasts for 26-28 days. The adults share all parental duties, and the chicks start clambering about before they can fly. The chicks are covered in dense brownish down and are fed regurgitated food by the parents. They fledge about 23 days after hatching and become completely independent at the age of 7 weeks.
Grey go-away-birds are important dispersers of the seeds within their native ecosystem. They feed on various fruits including exotic invasives like seringa, and disperse their seeds.
