Researchers at the University of East Anglia have found out why birds are migrating earlier and earlier each year.
Experts have long suspected climate change is somehow driving this advancing migration pattern. But new research published today reveals that individual birds migrate like clockwork -- arriving at the same time each year.
However, climate warming is resulting in earlier nesting and hatching earlier each year, and this appears to be linked to the advancing migration.
