The Broad-winged Hawk is a compact Buteo with relatively short, broad wings and a short, square-tipped tail. Adults have brown upperparts, pale underparts with fine horizontal barring, and a distinctive black-and-white banded tail. Juveniles are lighter below with streaked underparts and less distinct tail banding. Body length is typically 34–44 cm, wingspan 81–100 cm, and mass 265–560 g. The species is built for soaring and gliding, with broad wings that aid in thermal riding during migration. Plumage shows little sexual dimorphism, though females are slightly larger. Vocalizations are high-pitched, whistled calls, especially during breeding.

Prefers forest edges, open woodlands, and clearings; in Costa Rica, found from lowlands to montane slopes, including second-growth and agricultural mosaics.
Opportunistic predator; consumes small mammals, reptiles, amphibians, birds, and large insects.
Diurnal; solitary or in pairs during breeding season. Highly social during migration, forming large flocks in thermals. Uses soaring flight to conserve energy. Courtship involves aerial displays and vocal calls. Territorial during breeding, but tolerant of conspecifics in non-breeding season.
Notable for spectacular mass migrations through Central America, visible at hawk watch sites.
Some populations are migratory, while others are year-round residents in the tropics.
Known for “kettling” behavior, soaring in large spirals during migration.

Powerful, blunt‑snouted requiem shark easily recognised by dark vertical bars and blotches on a bluish‑grey to olive dorsum (most vivid in juveniles, fading in large adults). Body robust with pronounced keel on caudal peduncle and a low interdorsal ridge absent. First dorsal fin large, apex rounded; second dorsal and anal relatively small.
