What Animals Migrate In Autumn

In North America free-tailed bats migrate in huge numbers to hibernation sites in Texas and Mexico.

What animals migrate in autumn. The cycle is controlled by changes in the amount of daylight and the weather. Hedgehogs and bats are two examples of British hibernating animals. When hedgehogs are born there can be up to seven babies in a single litter their coat of spines are soft and short.

For example swallows migrate south once the weather begins to cool and their food sources dwindle. For example the Arctic tern nests close to the North Pole in the summer. Around the month of October the gray whales in the Alaskan waters start the migration from the feeding ground to the Gulf of California and Baja peninsula.

Many see migration as part of a yearly cycle of changes a bird goes through. And we see the arrival of migrant Geese and Swan species in the Autumn as they escape the. Even rarer species like Yellow-browed Warbler are sometimes found amongst tit flocks in October and November.

Some species travel here for the winter and others arrive in spring and summer. Some of Britains resident birds like partridges never move than a kilometre from their birthplace but more than 40 per cent of the worlds bird population are migrants. Scientists are still studying this.

In the UK pipistrelle bats migrate in autumn from the north to spend winter in the warmer south-west. Berries that emerge on bushes provide important nutrients for migratory birds such as crows and geese as they pass through on their seasonal migration routes. Birds can fly very long distances.

The main reason animals migrate is to escape adverse conditions by moving to areas in which conditions are more favourable for their own and their offsprings survival. Other migratory creatures include whales and dolphins bats butterflies and fish. As winter sets in Alaska most of the ocean animals migrate southwards to the warmer oceans prompting the grey whales to follow.
