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 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...

GBIF citizen-science records
It is estimated from how often the Grey Kestrel is recorded against all the birds logged in Kidepo Valley National Park (84 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.
