The grey-headed kingfisher (Halcyon leucocephala) is a species of kingfisher that has a wide distribution from the Cape Verde Islands off the north-west coast of Africa to Mauritania, Senegal and Gambia, east to Ethiopia, Somalia and southern Arabia and south to South Africa.
The sexes are similar. The adult of the nominate race H. l. leucocephala has a pale grey head, black mantle and back, bright blue rump, wings and tail, and chestnut underparts. Subspecies H. l. pallidiventris has a darker grey head and paler chestnut underparts but is otherwise similar. The beak is long, red and sharp. This bird grows to an average length of 21 cm. The song is a succession of notes, ascending, descending and then ascending again, becoming increasingly strident. The warning call is a series of sharp notes, "tchk, tchk, tchk, tchk".
