Why Bar-Tailed Godwits Can Fly Nonstop From Alaska To New Zealand
How their body changes before and after take-off

Nature never stops impressing me. For example, some breeds of migrating birds fly incredible distances, such as the bar-tailed godwit (Limosa lapponica baueri). This large wading bird flies more than 11,000 kilometres (6,835 miles) one way, from Alaska to New Zealand and Australia and back, each year. Some of them can make this journey non-stop, without stopovers.
Bar-tailed godwits spend their springs and summers in western Alaska, breeding and raising chicks on the Alaska coasts. In late summer and fall, they gather together in the Yukon-Kuskokwim Delta and Alaska Peninsula and begin to migrate to the warmth of Australia and New Zealand.
