Halcyon leucocephala (Statius Müller, 1776)

The grey-headed kingfisher (Halcyon leucocephala) 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 first formal description of the grey-headed kingfisher was by the German zoologist Philipp Ludwig Statius Müller in 1776. He coined the binomial name Alcedo leucocephala. The current genus Halcyon was introduced by the English naturalist and artist William John Swainson in 1821. The name of the genus is from the classical Greek alkuōn, a mythical bird, generally associated with the kingfisher. The specific epithet leucocephala is from the classical Greek leukos meaning "white" and -kephalos for "-headed".

Five subspecies are recognised:

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 (8.3 in). 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".
