The Red-crowned Crane (Grus japonensis), also known as the Japanese Crane or Manchurian Crane, is a large bird belonging to the order of wetland birds. Its primary geographic distribution is centered in East Asia, with major populations found in southeastern Russia, northeastern China, the Japanese island of Hokkaido, and the Korean Peninsula.

This species possesses long legs and a slender neck adapted for foraging in deep wetland environments. Its hunting behavior is primarily omnivorous, involving the consumption of fish, amphibians, and aquatic plants. A unique identifying feature is a patch of bare red skin on the crown of the head, which becomes brighter when the bird is excited or aggressive.
