Among animals, birds spend considerable time preening their feathers. This is done to remove ectoparasites, keep them in good aerodynamic condition, and waterproof them. To do that, they use the preen oil secreted by the uropygial gland, the dust of down feathers, or other means such as dust-bathing or anting.
The grey go-away-bird (Corythaixoides 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. They regularly form groups and parties that forage in tree tops, or dust bathe on the ground. Especially when disturbed, make their presence known by their characteristically loud and nasal “kweh” or “go-way” calls, with the last syllable typically a descending drawl.
