The Far Eastern curlew, a shorebird, spends its breeding season in northeastern Asia, including Siberia, Kamchatka and Mongolia. Its breeding habitat is marshy and swampy wetlands and lakeshores. Most individuals winter in coastal Australia, with a few heading to South Korea, Thailand, Philippines and New Zealand, where they stay at estuaries, beaches, and salt marshes.
The whooping crane, the tallest North American bird, is an endangered species named for its whooping call. About 300 whooping cranes breed in Wood Buffalo National Park in Canada and migrate to the Gulf coast of Texas, USA, for the winter. The Salt Plains National Wildlife Refuge in Oklahoma is a major stopover. Conservationists are trying to establish new wild populations from captive birds.
