Siberian crane [SEP] Feeding
These cranes feed mainly on plants although they are omnivorous. In the summer grounds they feed on a range of plants including the roots of hellebore ("Veratrum misae"), seeds of "Empetrum nigrum" as well as small rodents (lemmings and voles), earthworms and fish. They were earlier thought to be predominantly fish eating on the basis of the serrated edge to their bill, but later studies suggest that they take animal prey mainly when the vegetation is covered by snow. They also swallow pebbles and grit to aid in crushing food in their crop. In their wintering grounds in China, they have been noted to feed to a large extent on the submerged leaves of "Vallisneria spiralis".
