The eastern buzzard or Japanese buzzard (Buteo japonicus) is a medium to large bird of prey that is sometimes considered a subspecies of the widespread common buzzard (Buteo buteo). It was formerly treated as a subspecies of the common buzzard, but molecular phylogenetic studies revealed that B. buteo as then circumscribed was polyphyletic, leading to the recognition of the eastern buzzard and Himalayan buzzard (B. refectus) as distinct species. It is native to East Asia and some parts of Russia and South Asia, with some birds wintering in Southeast Asia. It is similar to the steppe buzzard. It is carnivorous.
It includes four subspecies: B. j. burmanicus: breeds in Siberia, Mongolia, northern China, and North Korea, winters in Southeast Asia B. j. japonicus: breeds only in Japan, winters from southern Japan to southeastern China and Taiwan

With luck
About 10% of wildlife watchers report an Eastern Buzzard sighting in Busan on a given day, based on 29 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report an Eastern Buzzard in Busan on a given day, against under 5% in May, the lowest month. That is one of Busan's driest months, with about 40 mm of rain against 290 mm in July.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Eastern Buzzard sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
6th of 34
Of the 34 cities where we can rate Eastern Buzzard sightings, Busan ranks 6th at about 10%. The best odds are in Quanzhou (China, about 20%), Jinhua (China, about 20%) and Sendai (Japan, about 10%).
Same family: Accipitridae
The closest relatives of the Eastern Buzzard that you can see in Busan (family Accipitridae, Hawks, Eagles, and Kites) are Black Kite (about 20%) and Eurasian Sparrowhawk (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Buzzard is recorded against all the birds logged in Busan (29 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.
