Catching a Non-Stop, Transatlantic Flight on a Songbird’s Back

Scientists have suspected that the blackpoll warbler—a small, 12-gram songbird—made non-stop migrations over open water to its winter habitats. To find out, ecologist Bill DeLuca and his team caught a flight on the birds by strapping small geolocators onto their backs. The researchers published their findings in the journal Biology Letters. DeLuca discusses just how far these birds journeyed.
