The black-rumped magpie (Pica bottanensis) is a species of magpie native to west-central China and Bhutan, and possibly also irregularly in Sikkim in India, and in eastern Nepal. It is similar to other magpies in the genus Pica, with pied plumage with bluish-green iridescent wings and tail, but differs from the other species in the genus except for Asir magpie in having no white on the rump. It was described as a species in 1840, but had long been treated as a subspecies of Eurasian magpie, before being restored to species rank in 2018. In breeding behaviour it is largely similar to other Pica magpies, laying a single brood from April to June.
The black-rumped magpie was first described by Adolphe Delessert in 1840 as a species Pica bottanensis. In 1877, Richard Bowdler Sharpe dismissed it as a synonym of the Eurasian magpie, but this was strongly disputed by Allan Octavian Hume in 1877 and 1880, maintaining it as a distinct species. It remained accepted as a distinct species (with also probably the first citation of the English name 'Black-rumped Magpie') in Eugene W. Oates's 1889 The fauna of British India, including Ceylon and Burma. By 1928, Frank Ludlow cited it... Wikipedia →

Possible
About 20% of wildlife watchers report a Black-rumped Magpie sighting in Xining on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 18th most-seen of the 38 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
Only Xining, in our data
Xining is the only city on Wallace's Line with enough records to rate Black-rumped Magpie sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-rumped Magpie is recorded against all the birds logged in Xining (13 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.
