The African yellow warbler (Iduna natalensis), also known as Natal yellow warbler, dark-capped yellow warbler or yellow flycatcher-warbler, is a species of Acrocephalidae warblers; formerly, these were placed in the paraphyletic "Old World warblers".
The African yellow warbler is a medium-sized warbler in which the whole of the upperparts and tail are yellowish-brown, with a slightly browner crown and yellower rump. The wings have brown feathers edged with yellow. The underparts are bright yellow with an olive wash on the sides of the breast, flanks and lower belly. The bill is pale on the upper mandible and blackish on the lower, and the legs are blackish. Females have duller underparts, and the juveniles are similar to the males but are buffier. The total length is 13 cm (5.1 in) and the birds weigh between 10 and 15 g (0.35 and 0.53 oz).

With luck
About 10% of wildlife watchers report an African Yellow-Warbler sighting in Harare on a given day, based on 68 verified sightings from GBIF citizen-science data. It is the 74th most-seen of the 213 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
May and December–January
In those months about 20% of wildlife watchers report an African Yellow-Warbler in Harare on a given day, against under 5% in April, July and October, the lowest months. Those are among Harare's wettest months, with about 130 mm of rain a month against almost none in August.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most African Yellow-Warbler 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 5 cities where we can rate African Yellow-Warbler sightings, Harare has the highest daily chance: about 10%. Next come Nairobi (Kenya, about 10%) and Addis Ababa (Ethiopia, about 10%).
GBIF citizen-science records
It is estimated from how often the African Yellow-Warbler is recorded against all the birds logged in Harare (68 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.
