The grey-faced buzzard (Butastur indicus) is an Asian bird of prey. It is typically 41–46 cm (16–18 in) in length, making it a small-sized raptor. It breeds in Manchuria, Korea and Japan; it winters in South-east Asia. It is a bird of open land. It eats lizards, small mammals and large insects.
The adult has a grey head, breast and neck, white throat, black moustaches and mesial stripes, brown back and upperwings, and brown bars on white underparts and underwings. The juvenile is brown and mottled above, pale below with brown streaks, and has a broad white supercilium and brown face.
The gray-faced buzzard was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the eagles, hawks and relatives in the genus Falco and coined the binomial name Falco indicus. Gmelin based his account on the "Javan hawk" that had been described in 1781 by John Latham from a specimen in the Leverian collection that had been obtained in February 1780 at Princes Island off the westernmost cape of Java during Captain Cook's last voyage. The gray-faced buzzard is now one of four species... Wikipedia →

Rare
Under 5% of wildlife watchers report a Gray-faced Buzzard sighting in Taichung on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 99th most-seen of the 121 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 a Gray-faced Buzzard in Taichung 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 Gray-faced Buzzard sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 19
Of the 19 cities where we can rate Gray-faced Buzzard sightings, Taichung ranks 12th at under 5%. The best odds are in Naha (Japan, about 10%), Wenzhou (China, about 10%) and Busan (South Korea, under 5%).
Same family: Accipitridae
The closest relatives of the Gray-faced Buzzard that you can see in Taichung (family Accipitridae, Hawks, Eagles, and Kites) are Black-winged Kite (about 10%) and Crested Serpent Eagle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray-faced Buzzard is recorded against all the birds logged in Taichung (22 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.
