The grey kestrel (Falco ardosiaceus) is an African bird of prey belonging to the falcon family Falconidae. Its closest relatives are the banded kestrel and Dickinson's kestrel and the three are sometimes placed in the subgenus Dissodectes.
It is a fairly small, stocky kestrel with a large, flat-topped head and fairly short wings that don't reach past the tip of the tail when at rest. It is 28–33 cm long with a wingspan of 58–72 cm and a weight of up to 300 grams. The female is 4-11% larger and 5-11% heavier than the male. The plumage of the adult is uniformly dark grey apart from darker wingtips, faint dark streaking on the body and slightly barred flight feathers. The feet and cere are yellow and there is bare yellow skin around the eye. The most similar species is the sooty falcon which has a more rounded head, long wings extending past the tail and less yellow around the eye.
Juvenile grey kestrels are browner than the adults with a greenish cere and greenish around the eye. Juvenile Dickinson's kestrels are similar but have a barred tail and a more strongly barred underwing. The grey kestrel is generally silent outside the breeding season but has a shrill, chattering...

Likely
About 50% of wildlife watchers report a Grey Kestrel sighting in Murchison Falls National Park on a given day, based on 629 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 424 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
June and July
In those months about 60% of wildlife watchers report a Grey Kestrel in Murchison Falls National Park on a given day, against about 20% in October, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Grey Kestrel sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 18 parks where we can rate Grey Kestrel sightings, Murchison Falls National Park has the highest daily chance: about 50%. Next come Niokolo-Koba National Park (Senegal, about 40%) and Ruaha National Park (Tanzania, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Grey Kestrel is recorded against all the birds logged in Murchison Falls National Park (629 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.
