The Japanese grosbeak (Eophona personata) or Ikaru is a finch native to the East Palearctic. It is also sometimes referred to as the Japanese or masked hawfinch due to superficial similarities to the well-known Eurasian species.
This is a large finch, with a reported weight of 80 g (2.8 oz) (for a single male) and a length of 18 to 23 cm (7.1 to 9.1 in). Among standard measurements, the wing chord is 10.2 to 11.7 cm (4.0 to 4.6 in), the tail is 8.3 to 9.5 cm (3.3 to 3.7 in) and the culmen is 2.1 to 2.6 cm (0.83 to 1.02 in). The signature feature of the Japanese grosbeak is its large, pointed bright yellow bill. The adult grosbeak has a large black marking extending from the nape to the chin and ear-coverts to the neck. The side of the neck is a contrasting pale whitish grey. The bird's underside is a more dull grey. The back is greyish-brown while the flanks are washed with a gingery or tawny-brown colour. The wings and tail are black but for a white patch on the inner-coverts and band of white in the middle of the primaries, which is visible in flight. Juveniles are a duller grey overall with no black on head. Wikipedia →

Rare
Under 5% of wildlife watchers report a Japanese Grosbeak sighting in Hiroshima on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 53rd most-seen of the 59 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
February to May
In those months about 10% of wildlife watchers report a Japanese Grosbeak in Hiroshima on a given day, against under 5% in June to January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Japanese Grosbeak sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 16
Of the 16 cities where we can rate Japanese Grosbeak sightings, Hiroshima ranks 4th at under 5%. The best odds are in Sendai (Japan, about 10%), Osaka (Japan, about 10%) and Qingdao (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Japanese Grosbeak is recorded against all the birds logged in Hiroshima (7 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.
