A third group undertakes longer trips, staying away for weeks near feeding grounds. These migratory oilbirds flew less each night, conserving energy by resting closer to food. Researchers tracked twenty-one birds using devices to record their movements and flight times.from Science News: Fresh Discoveries, Research & Breakthroughs https://ift.tt/7vctQJF
