The isabelline wheatear (Oenanthe isabellina) is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher in the family Muscicapidae. It is a migratory insectivorous bird. Its habitat is steppe and open countryside and it breeds in southern Russia and Central Asia to northern Pakistan, wintering in Africa and northwestern India. It is a very rare vagrant to western Europe.
In colouring it resembles a female northern wheatear but it is larger at 15–16.5 centimetres (5.9–6.5 in) in length, more upright and more tawny in colour, and has more black on its tail.

With luck
About 10% of wildlife watchers report an Isabelline Wheatear sighting in Ulaanbaatar on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 50th most-seen of the 63 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April and June–August
In those months about 10% of wildlife watchers report an Isabelline Wheatear in Ulaanbaatar on a given day, against under 5% in May and September–March, the lowest months. Those are among Ulaanbaatar's wettest months, with about 45 mm of rain a month against almost none in January.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Isabelline Wheatear sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 18 cities where we can rate Isabelline Wheatear sightings, Ulaanbaatar ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Kuwait City (Kuwait, about 10%), Riyadh (Saudi Arabia, about 10%) and Doha (Qatar, about 10%).
GBIF citizen-science records
It is estimated from how often the Isabelline Wheatear is recorded against all the birds logged in Ulaanbaatar (11 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.
