UrduResearchers at the Max Planck Institute of Animal Behavior and University of Konstanz in Germany have identified how large land birds fly nonstop for hundreds of kilometers over the open ocean—without taking a break for food or rest.

More than a bumpy ride: turbulence offers boost to birds
By combining wind speed data with the measured accelerations of a golden eagle outfitted with GPS tracking instruments, researchers suggest that, rather than hindering flight, turbulence is a source of energy that birds may use to their advantage.
Migration and Molt Affect How Birds Change Their Colors
Before the journey, many birds molt their bright feathers, replacing them with a more subdued palette. Watching this molt led scientists to wonder how feather color changes relate to the migrations many birds undertake twice each year.
Mapping out rest stops for migrating birds
Researchers have developed a new metric called the stopover-to-passage ratio that can help determine if a majority of birds are flying over a particular site or stopping at the site to refuel or rest. This can have important implications for what is done on the ground to help migratory birds.
