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.
Buff-necked Ibis
71–76 cm. White head and neck with rusty tone; black back; buff breast; bare yellow facial skin. Widespread in South America from Colombia and Venezuela south to Argentina in open savannas and grasslands. Feeds on invertebrates, lizards, and frogs. Common; often in pairs or small groups.
