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 Osaka on a given day, based on 167 verified sightings from GBIF citizen-science data. It is the 76th most-seen of the 180 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Red-billed Leiothrix in Osaka on a given day, so our monthly data shows no clear season.
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.
10th of 15
Of the 15 cities where we can rate Red-billed Leiothrix sightings, Osaka ranks 10th at under 5%. The best odds are in Guiyang (China, about 50%), Chongqing (China, about 10%) and Fukuoka (Japan, about 10%).
Same order: Passeriformes
The closest relatives of the Red-billed Leiothrix that you can see in Osaka (order Passeriformes, Perching Birds) are Eurasian Tree Sparrow (about 80%), Brown-eared Bulbul (about 70%) and Large-billed Crow (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-billed Leiothrix is recorded against all the birds logged in Osaka (167 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.
