About These Birds
Roseate Spoonbill
The roseate spoonbill is the only spoonbill species in the Americas and one of the most striking wading birds in the Western Hemisphere. Like flamingos, their pink color comes from carotenoid pigments in their crustacean prey. Nearly hunted to extinction for their plumes in the 19th century, they have recovered substantially.
Black-faced Ibis
71 cm. White head; black face mask and back; buff underparts; bare black-and-red facial skin; pink legs. Resident in southern South America (Chile, Argentina) and Andean foothills. Feeds on invertebrates in grasslands and wetlands. Moves seasonally; some populations migratory.
