About These Birds
Mute Swan
The mute swan is one of the heaviest flying birds, with males weighing up to 14 kg. Despite its name, it is not truly mute, producing hissing, grunting, and snorting sounds. Mute swans form lifelong pair bonds and their aggressive defense of nesting territory is well known.
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.
