Animals That Migrate In Autumn. What do animals do during fall: There are a few mammals, like some bats, caribou and elk, and whales that travel in search of food each winter.
Why animals are driven to migrate as the year turns, millions of birds and animals cross oceans and continents but climate change may have unpredictable consequences for this. For example, swallows migrate south once the weather begins to cool and their food sources dwindle. Migration is part of the life cycle of these animals.

This movement is called migration. Other kinds of animals migrate, too. From deer to birds, and elsewhere bears and elk, many species are triggered by the shortening days to switch into a frenetic mode. The rspb’s gemma butlin highlights ten species to look out for this autumn, some of which have travelled 6,000 miles on their epic migration journeys.
