The African marsh harrier (Circus ranivorus) is a bird of prey belonging to the harrier genus Circus. It is largely resident in wetland habitats in southern, central and eastern Africa from South Africa north to South Sudan.
African Marsh harrier females are larger than males and they are 44–47 centimetres (17–19 in) in length, with females being about 30% heavier than males (Simmons and Simmons 2000). Adults, (like the male bird right) have yellow eyes, but brown eyes when immature. Both sexes are mostly brown with pale streakings on the head, breast, forewing and rufous on the thighs and the belly. Adult males differ from females in that they have a pale grey wash to the dorsal secondaries and primaries. The female's are brown. The juvenile is dark brown and may have a pale breastband and pale markings on the head. The tail and flight feathers have dark barring at all ages, but this is rarely visible in the juvenile birds.
It resembles a small Eurasian marsh harrier but is slimmer and paler brown. It could be mistaken for an immature Montagu's harrier or pallid harrier, but the African marsh harrier can be readily distinguished from them by its lack of a white rump... Wikipedia →

Rare
Under 5% of wildlife watchers report an African Marsh-Harrier sighting in Serengeti National Park on a given day, based on 64 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 281st most-seen of the 469 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.
February and March
In those months about 10% of wildlife watchers report an African Marsh-Harrier in Serengeti National Park on a given day, against under 5% in April to January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most African Marsh-Harrier sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
15th of 23
Of the 23 parks where we can rate African Marsh-Harrier sightings, Serengeti National Park ranks 15th at under 5%. The best odds are in West Coast National Park (South Africa, about 40%), Akagera National Park (Rwanda, about 10%) and Chobe National Park (Botswana, about 10%).
Same genus: Circus
The closest relatives of the African Marsh-Harrier that you can see in Serengeti National Park (genus Circus, Harriers) are Montagu's Harrier (about 10%) and Pale Harrier (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the African Marsh-Harrier is recorded against all the birds logged in Serengeti National Park (64 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.
