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 Cape Town on a given day, based on 51 verified sightings from GBIF citizen-science data. It is the 133rd most-seen of the 196 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report an African Marsh-Harrier in Cape Town on a given day, against under 5% in July to May, the lowest months. That is one of Cape Town's wettest months, with about 140 mm of rain against 15 mm in February.
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.
Among the best
Of the 4 cities where we can rate African Marsh-Harrier sightings, Cape Town ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Kigali (Rwanda, under 5%) and Kampala (Uganda, under 5%).
Same family: Accipitridae
The closest relatives of the African Marsh-Harrier that you can see in Cape Town (family Accipitridae, Hawks, Eagles, and Kites) are Jackal Buzzard (about 10%), Black-winged Kite (about 10%) and Black Kite (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 Cape Town (51 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.
