The red-billed leiothrix (Leiothrix lutea) is a member of the family Leiothrichidae, native to southern China and the Himalayas.

It has also been introduced in various parts of the world, with small populations of escapees having existed in Japan since the 1980s. It has become a common cagebird and amongst aviculturists it goes by various names, including Pekin robin, Pekin nightingale, Japanese nightingale, and Japanese (hill) robin, these all being misnomers as it is not native to Japan (although it has been introduced and naturalised there), nor is it a robin or a nightingale.
The red-billed leiothrix was formally described in 1786 by the Austrian naturalist Giovanni Antonio Scopoli under the binomial name Sylvia lutea. Scopoli based his account on "La mésange de Nanguin" that had been described and illustrated in 1782 by the French naturalist Pierre Sonnerat in the second volume of his book Voyage aux Indes orientales et à...

With luck
About 10% of wildlife watchers report a Red-billed Leiothrix sighting in Jim Corbett National Park on a given day, based on 422 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 93rd most-seen of the 368 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July and August
In those months about 30% of wildlife watchers report a Red-billed Leiothrix in Jim Corbett National Park on a given day, against about 10% in February–June and October, the lowest months. Those are among Jim Corbett National Park's wettest months, with about 350 mm of rain a month against almost none in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red-billed Leiothrix 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 parks where we can rate Red-billed Leiothrix sightings, Jim Corbett National Park has the highest daily chance: about 10%. Next come Langtang National Park (Nepal, about 10%) and Ordesa y Monte Perdido National Park (Spain, under 5%).
GBIF citizen-science records
It is estimated from how often the Red-billed Leiothrix is recorded against all the birds logged in Jim Corbett National Park (422 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.
