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.
Straw-necked Ibis
59–76 cm. White with black neck bristles; bare dark head; yellowish bill. Endemic to Australia in grasslands, pastures, and inland wetlands. Nomadic; follows rainfall across the continent. Feeds on insects and invertebrates in dry grassland. Often seen in mixed flocks with Australian Ibis.
