About These Birds
Common Raven
The common raven is among the most intelligent birds, demonstrating tool use, future planning, and social manipulation in scientific studies. In many cultures, ravens feature prominently in mythology as creators, tricksters, or messengers. Their complex vocalizations include over 30 distinct calls.
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.
