Size Comparison
Habitat Comparison
Peregrine Falcon
Diverse habitats from tundra to tropics, typically near cliffs or tall structures. Increasingly found in cities nesting on skyscrapers and bridges.
Red-crowned Crane
Freshwater marshes, bogs, and wet grasslands for breeding. Winters in coastal mudflats, estuaries, and rice paddies.
Song & Call Comparison
Peregrine Falcon
A harsh, wailing 'kak-kak-kak-kak' repeated rapidly in defense of the nest. Alarm call is a long screaming 'raaak'. Mostly silent away from breeding sites.
Red-crowned Crane
Spectacular unison 'bugling' call: a clear, resonant, far-carrying trumpet 'kru-ru-ru' given by paired birds simultaneously. Among the most majestic bird calls in Asia.
Geographic Range & Migration
Peregrine Falcon
One of the most widespread birds, found on every continent except Antarctica. Migratory populations travel vast distances between breeding and wintering grounds.
Red-crowned Crane
Eastern Asia — breeds in northeastern China, southeastern Russia, and Hokkaido, Japan. Winters in Korea and eastern China.

About These Birds
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.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
