Recent studies using satellite telemetry or geolocators have shown that some bird species are capable of very long nonstop flight during migration, far longer than previously thought. Some of the longest belong to Bar-tailed Godwits, which have been tracked performing nonstop flights of over 11,000 km (or about 7,000 miles). Ruddy Turnstones perform similarly impressive flights. A new study in PLoS Biology tries to measure whether there are any limits to nonstop flights. (via A DC Birding Blog: How Far Can a Bird Fly Nonstop During Migration?
