Many Audubon members are familiar with tales of long-distance migrants.  Arctic Terns, for example, migrate from the far northern reaches of North America to the tip of South America and back the next spring, an annual journey of about 22,000 miles.  But for marathon flights, nothing beats the Bar-tailed Godwit.  Some of these incredible flying machines fly non-stop from Alaska to New Zealand, an 11,000 mile marathon flight.

You can learn more about this remarkable bird and its migration at the USGS Alaska Science Center Web site.
