Tropical winter habitat drives natal dispersal of young migratory birds

A new study by scientists at the Migratory Bird Center at the Smithsonian’s National Zoo shows that the factors determining where birds settle and nest in the first breeding season depends on the habitat they used during their first winter in the tropics. The determining factor in where a bird settles for its first breeding season relative to its hatching site—also known as natal dispersal—was previously unknown.
