Other subspecies are all-year residents on Caribbean islands. As in most raptors, females are slightly larger than males. Broad-winged hawks' wings are relatively short and broad with a tapered, somewhat pointed appearance. The two types of coloration are a dark morph with fewer white areas and a light morph that is more pale overall. Although the broad-winged hawk's overall population is increasing, populations are declining in some parts of its breeding range because of forest fragmentation.
The broad-winged hawk is a relatively small Buteo species, with a body size from 32 to 44 cm (13 to 17 in) in length and a weight 265 to 560 g (9.3 to 19.8 oz). The tail is relatively short, measuring 14.5–19.0 cm (5.7–7.5 in) in length. The tarsi measure from 5.6 to 6.6 cm (2.2 to 2.6 in). As in most raptors, females are slightly larger than males.

GBIF citizen-science records
It is estimated from how often the Broad-winged Hawk is recorded against all the birds logged in San José (520 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.
