The grey-headed kingfisher (Halcyon leucocephala) is a species of bird in the kingfisher family, Alcedinidae. It is found across large parts of Africa and southern Arabia, from Mauritania through Senegal and the Gambia, east to Ethiopia, Somalia, Yemen, Oman and Saudi Arabia, and south all the way through to South Africa. It is also found in islands off the African coast such as the Cape Verde islands and Zanzibar.
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 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".

With luck
About 10% of wildlife watchers report a Gray-headed Kingfisher sighting in Abuja on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 91st most-seen of the 131 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February–June and November–December
In those months about 10% of wildlife watchers report a Gray-headed Kingfisher in Abuja on a given day, against under 5% in January and July–October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Gray-headed Kingfisher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 10
Of the 10 cities where we can rate Gray-headed Kingfisher sightings, Abuja ranks 5th at about 10%. The best odds are in Dar es-Salaam (Tanzania, about 30%), Mombasa (Kenya, about 20%) and Dakar (Senegal, about 10%).
GBIF citizen-science records
It is estimated from how often the Gray-headed Kingfisher is recorded against all the birds logged in Abuja (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
