How do birds spend the winter?

If it is a migratory bird, it will migrate to a warm place to spend the winter before winter; if it is a non-migratory bird, it will find a relatively warm and dry place to sleep in order to reduce consumption to spend the winter. Therefore, different birds spend the winter in different ways.

Introduction of some birds to spend the winter

1. Nightingale

When the cold winter season of lack of food comes, the Nighthawk will find a tree hole to hide from the wind and go into dormancy. At this time, its body temperature will drop from 38 degrees to about 20 degrees in order to reduce the consumption of nutrients in the body.

two。 Swallow

Some swallows living in northern Europe also gather in groups and go dormant whenever they are hit by a cold wave in winter. The adult birds of Swift fly to the warm south, while the newly hatched birds in the nest go into dormancy, waiting for their parents to return to feed.

3. White-breasted seedling chicken

Yangji chooses dry stone or mud holes and hibernates inside. Yangji do not eat in the cave, or do little activity, the number of breathing is reduced, blood circulation slows down, metabolism weakens, as much as possible to reduce the consumption of nutrients in the body, relying on stored fat to maintain life.

4. Wild goose

When geese migrate, they like to form a large number of people together, forming a zigzag shape and a herringbone shape. Each migration takes about 1-2 months, northward in spring and southward in autumn.

5. Budgerigar

Budgerigars behave in a manner similar to migration. In Australia, they occupy the north every winter (June to September) and gather in the south in summer (September to January). Prefer to go to North Australia and region in the colder season, and go to South Australia in the hot season.

6. Arctic Tern

Distributed in and around the Arctic, migratory birds experience two summers each year, migrating south from the northern breeding area to the ocean near Antarctica, and then northward back to the breeding area, covering a total journey of more than 40000 kilometers, which is the longest migration route of any known animal.
