The rough-legged buzzard (Europe) or rough-legged hawk (North America) (Buteo lagopus) is a medium-large bird of prey. It is found in arctic and subarctic regions of North America, Europe, and Asia during the breeding season, and migrates south for the winter. Historically, it was also known as "rough-legged falcon" in such works as John James Audubon's The Birds of America.
Nests are typically located on cliffs, bluffs or in trees. The clutch sizes are variable with food availability, but usually three to five eggs are laid. They hunt over open land, feeding primarily on small mammals, mainly lemmings and voles. Along with the kestrels, kites, and osprey, this is one of the few birds of prey to hover regularly.
This fairly large raptorial species is 46–68 cm (18–27 in) with wingspan ranging from 120 to 153 cm (47 to 60 in). Individuals can weigh from 600 to 1,660 g (1.32 to 3.66 lb) with females typically being larger and heavier than males. Weights appear to increase from summer to winter in adults, going from an average of 822 to 1,027 g (1.812 to 2.264 lb) in males and from 1,080 to 1,278 g (2.381 to 2.818 lb) in females.

Rare
Under 5% of wildlife watchers report a Rough-legged Hawk sighting in Boston on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 283rd most-seen of the 283 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 Rough-legged Hawk in Boston 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 Rough-legged Hawk sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
23rd of 23
Of the 23 cities where we can rate Rough-legged Hawk sightings, Boston ranks 23rd at under 5%. The best odds are in Novosibirsk (Russia, about 10%), Kyiv (Ukraine, under 5%) and Yekaterinburg (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Rough-legged Hawk is recorded against all the birds logged in Boston (13 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.
