The eastern olivaceous warbler (Iduna pallida), known simply as the olivaceous warbler when its western relative is referred to as the 'isabelline warbler', is a small passerine bird with drab plumage tones, that is native to the Old World. For the most part it breeds in southeastern Europe, the Middle East and adjacent western Asia, and winters in the northern Afrotropics.
The eastern olivaceous warbler is a "warbler", formerly placed in the Old World warblers when these were a paraphyletic wastebin taxon. It is now considered a member of the acrocephaline warblers, Acrocephalidae, in the tree warbler genus Iduna. It was formerly regarded as part of a wider "olivaceous warbler" species, but as a result of modern taxonomic developments, this species is now usually considered distinct from the western olivaceous warbler, Iduna opaca.
Keyserling and Blasius gave no explanation of the genus name Iduna. The specific pallida is Latin for "pale". This small passerine bird is found in dry open country, including cultivation, with bushes or some trees. Like most warblers it is insectivorous.
It is migratory, wintering in sub-Saharan Africa... Wikipedia →

Possible
About 30% of wildlife watchers report an Eastern Olivaceous Warbler sighting in N'Djamena on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 15th most-seen of the 70 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 50% of wildlife watchers report an Eastern Olivaceous Warbler in N'Djamena on a given day, against about 20% in July and September, the lowest months. That is one of N'Djamena's driest months, with almost no rain against 190 mm in August. June, August and October–December have too few records to rate.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Eastern Olivaceous Warbler sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 26 cities where we can rate Eastern Olivaceous Warbler sightings, N'Djamena has the highest daily chance: about 30%. Next come Jerusalem (Israel, about 30%) and Abu Dhabi (United Arab Emirates, about 20%).
Same order: Passeriformes
The closest relatives of the Eastern Olivaceous Warbler that you can see in N'Djamena (order Passeriformes, Perching Birds) are Red-cheeked Cordon-bleu (about 60%), Common Bulbul (about 60%) and Bronze Mannikin (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Olivaceous Warbler is recorded against all the birds logged in N'Djamena (23 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.
