The Grey Go-away-bird (Corythaixoides concolor), also known as Grey Lourie or Grey Loerie, is a southern African bird of uniform grey with black beak. It is widespread in savanna woodland, and is a clumsy flier although extremely agile when clambering through tree crowns. It has a distinctive alarm call 'quare', which sounds like 'Go-away'. The crest is raised when excited.
