Found in northeast China, southeastern Russia, Mongolia, and eastern Japan, the red-crowned crane is 1 of the world’s largest crane species. They forage in pasturelands and winter in rivers, coastal salt marshes, freshwater marshes, rice paddies, and cultivated fields. There are 2 main breeding populations; 1 is migratory and the other is stationary. Due to illegal take & poisoning, water diversions (like dams), human disturbance, habitat destruction, and climate change, these birds are listed as Endangered by the IUCN and their populations are decreasing.

Now on to the Facts!
1.) These cranes eat fish, insects, aquatic invertebrates, amphibians, small mammals, grasses, reeds, heath berries, corn, cereal grains, and waste grain.
2.) Red-crowned cranes use high-pitched, penetrating calls with a loud, rattling kar-r-r-o-o-o at multiple variations to communicate.
3.) When they preen themselves, they will rub a special oil on their feathers that they secrete from a special gland located at the top of their tail. This helps to keep their feathers in good condition.
4.) When communicating aggression the males will inflate the red cap on the top of their head.
5.) In the Orient, this bird is a symbol of fidelity, love, and longevity.
