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).

Rare
Under 5% of wildlife watchers report an African Yellow-Warbler sighting in Gorongosa National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 179th most-seen of the 250 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April, September and November
In those months about 10% of wildlife watchers report an African Yellow-Warbler in Gorongosa National Park on a given day, against under 5% in February, May–August and October, the lowest months. March and December–January have too few records to rate.
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.
5th of 14
Of the 14 parks where we can rate African Yellow-Warbler sightings, Gorongosa National Park ranks 5th at under 5%. The best odds are in Mkomazi National Park (Tanzania, about 20%), Nairobi National Park (Kenya, about 10%) and Arusha National Park (Tanzania, about 10%).
Same order: Passeriformes
The closest relatives of the African Yellow-Warbler that you can see in Gorongosa National Park (order Passeriformes, Perching Birds) are Common Bulbul (about 70%), Black-backed Puffback (about 60%) and Fork-tailed Drongo (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the African Yellow-Warbler is recorded against all the birds logged in Gorongosa National Park (11 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.
