About These Birds
Dwarf Ibis
45–50 cm. Small ibis; dark brown with olive gloss; bare facial skin. Critically Endangered; endemic to São Tomé Island (Gulf of Guinea). Fewer than 250 birds; threatened by forest clearance and hunting. The world's smallest ibis; feeds on earthworms and invertebrates in moist forest.
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.
