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.
Peregrine Falcon
The peregrine falcon is the fastest animal on Earth, reaching speeds over 389 km/h during its characteristic hunting stoop. Like the bald eagle, peregrines suffered dramatic declines from DDT but have recovered through intensive conservation programs. They have adapted remarkably well to urban environments.
