This species is present in Russian Far East, China, Manchuria and Korea. It occurs in forests, mixed woods and bamboo forests of hilly and mountainous areas: it does not fear humans and also goes into gardens and orchards.
Eophona migratoria measures between eighteen and twenty centimeters in length, for a wingspan of 23–24 cm and a weight of 55-60 g. The appearance is massive, as is typical of the finches, with a large head. The beak is very strong and conical. The beak color is yellow (hence the common name of "yellow-billed grosbeak") with a black tip.

Rare
Under 5% of wildlife watchers report a Yellow-billed Grosbeak sighting in Tokyo on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 73rd most-seen of the 229 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.
January and March
In those months about 10% of wildlife watchers report a Yellow-billed Grosbeak in Tokyo on a given day, against under 5% in February and April–December, the lowest months.
30th of 33
Of the 33 cities where we can rate Yellow-billed Grosbeak sightings, Tokyo ranks 30th at under 5%. The best odds are in Wuhan (China, about 60%), Ningbo (China, about 50%) and Shanghai (China, about 50%).
GBIF citizen-science records
It is estimated from how often the Yellow-billed Grosbeak is recorded against all the birds logged in Tokyo (21 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.
