bird migration
Geese going south
Bird migration is the seasonal movement of birds between breeding and wintering grounds, often covering thousands of miles.
Species migrate to follow food sources, favorable weather, or breeding conditions.
Some birds migrate in dramatic V-formations; others travel alone at night.
The Arctic tern's migration spans pole to pole.
Migration timing serves as a marker of seasonal change: We knew spring had arrived when the swallows returned.
