Buteogallus aequinoctialis
The Rufous Crab Hawk, *Buteogallus aequinoctialis*, is a striking medium-sized raptor, often regarded as one of the most specialized predators of mangrove ecosystems along the Atlantic coast of South America. Averaging 46-56 cm (18-22 in) in length with a wingspan of 90-112 cm (35-44 in) and weighing 500-930 g (1.1-2.05 lbs), its deep rufous-chestnut plumage, contrasting with glossy black flight feathers and a distinctive black tail marked by a single broad white band, makes it unmistakable i...
Primarily inhabits coastal mangrove forests, estuaries, and tidal mudflats, typically at sea level or low elevations.
Feeds almost exclusively on crabs, particularly mangrove crabs, supplemented with other crustaceans, small fish, mollusks, and occasionally insects or small vertebrates; foraging involves wading and snatching prey from mudflats.
This diurnal raptor is often observed perched conspicuously on dead snags or exposed roots within the mangroves, patiently scanning the mudflats below. Its foraging strategy is highly specialized: it wades in shallow water or walks methodically over exposed mud, expertly snatching crabs with its ...
The Rufous Crab Hawk is a resident species distributed along the Atlantic coast of South America, strictly adhering to its preferred mangrove and estuarine habitats. Its breeding range extends from eastern Venezuela, through the Guianas (Guyana, Suriname, French Guiana), and extensively along the...
Least Concern
