Do birds hibernate?

Do birds hibernate?

Hibernation is a state when animals sleep during winter, especially where the winters are extremely cold and/or snowy. Not all animals hibernate. Animals such as bears, squirrels, bats, and hedgehogs hibernate. Some lizards and snakes hibernate.

When these animals hibernate, they will eat a lot of food and gain body weight beforehand to enable them to sleep throughout the winter. For example, squirrels can gain 50% of their body weight before hibernating.

Changing colour for winter

f&m Leave a comment

What animals change colour for winter?

Many animals, especially mammals, hibernate (sleep) in winter. Some animals lie dormant (similar to sleep, but lie still). Other animals, such as butterflies and moths and other insects, turn into cocoons and chrysalises in winter, waiting to emerge as adults in spring. Other animals grow their winter fur to keep them warm.

But some animals change colour to camouflage into their autumn and winter environment – brown among dry leaves and leaf litter, white in snowfields, and grey in clouded habitats.
