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".

Rare
Under 5% of wildlife watchers report a Gray-headed Kingfisher sighting in Semuliki National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 209th most-seen of the 280 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May, July and November
In those months about 10% of wildlife watchers report a Gray-headed Kingfisher in Semuliki National Park on a given day, against under 5% in June, August–October and December–April, 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.
32nd of 38
Of the 38 parks where we can rate Gray-headed Kingfisher sightings, Semuliki National Park ranks 32nd at under 5%. The best odds are in Meru National Park (Kenya, about 70%), Murchison Falls National Park (Uganda, about 60%) and Samburu National Reserve (Kenya, about 50%). All parks ranked.
Same genus: Halcyon
The closest relatives of the Gray-headed Kingfisher that you can see in Semuliki National Park (genus Halcyon, Typical Woodland Kingfishers) are Woodland Kingfisher (about 70%), Blue-breasted Kingfisher (about 40%) and Chocolate-backed Kingfisher (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray-headed Kingfisher is recorded against all the birds logged in Semuliki National Park (11 verified sightings from 2019 to 2026), 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.
