Whooping cranes eat both plants and animals. They are omnivores. They mostly eat crustaceans, small fish, insects, amphibians and reptiles but they will also eat grains, marsh plants and acorns.
Each fall, the only naturally occurring flock of Whooping cranes migrate south from Canada's Wood Buffalo National Park to their winter grounds in Texas at the Aransas National Wildlife Refuge. If a Whooping Crane catches a good gust of wind they can soar for quite a while without flapping their wings.
