The upland buzzard (Buteo hemilasius) is a species of bird of prey in the family Accipitridae. The largest species of the Buteo genus, this buzzard lives in mountainous grassy and rocky areas in areas of Central Asia, northern South Asia and East Asia from Kazakhstan to Korea. The upland buzzard is migratory but typically covers a short distance apparently to avoid snow cover that may hamper prey capture. This species primarily subsists on small mammals but does not shun alternate prey from small to large birds and insects. This little-known raptor has a large range, and though generally uncommon, it is not thought to be rare or declining as a species. As a result, it is classified as least concern by the IUCN.
The upland buzzard species was first described by Temminck and Schlegel in 1844 and is monotypic. Currently, this species is considered to form a superspecies with the long-legged buzzard. At one time, the upland buzzard was considered as conspecific with the long-legged species. A small molecular study found that there was not a strong genetic affinity between the upland and long-legged buzzards. There is some circumstantial claims that they will... Wikipedia →

Rare
Under 5% of wildlife watchers report an Upland Buzzard sighting in Seoul on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 159th most-seen of the 231 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Upland Buzzard in Seoul on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Upland Buzzard sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 cities where we can rate Upland Buzzard sightings, Seoul ranks 5th at under 5%. The best odds are in Ulaanbaatar (Mongolia, about 10%), Beijing (China, under 5%) and Taipei (Taiwan, under 5%).
GBIF citizen-science records
It is estimated from how often the Upland Buzzard is recorded against all the birds logged in Seoul (45 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.
