About These Birds
Puna Ibis
The Puna Ibis (Plegadis ridgwayi) is a South American member of the family Threskiornithidae, named in honor of the American ornithologist Robert Ridgway. It closely resembles the Glossy Ibis and White-faced Ibis in overall appearance, sharing the characteristic dark, iridescent plumage of the genus, though it tends to be somewhat smaller and shows subtle differences in the extent of facial skin color and iridescence. Adults display chestnut and purplish-brown body plumage with greenish and bronzy gloss on the wings and …
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.
