The red-billed leiothrix (Leiothrix lutea) is a member of the family Leiothrichidae, native to southern China and the Himalayas. Adults have bright red bills and a yellowish-white ring around their eyes. Their backs are dull olive green, and they have a bright yellow-orange throat with a yellow chin; females are somewhat duller than males, and juveniles have black bills. 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...

Rare
Under 5% of wildlife watchers report a Red-billed Leiothrix sighting in Royal Manas National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 293rd most-seen of the 388 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Red-billed Leiothrix in Royal Manas National Park on a given day, against under 5% in November to July, the lowest months. That is one of Royal Manas National Park's driest months, with about 130 mm of rain against 930 mm in July. August and September have too few records to rate.
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.
4th of 5
Of the 5 parks where we can rate Red-billed Leiothrix sightings, Royal Manas National Park ranks 4th at under 5%. The best odds are in Jim Corbett National Park (India, about 10%), 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 Royal Manas National Park (17 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.
