What migratory birds are there?

Migratory birds are divided into four categories: summer migratory birds, winter migratory birds, travelers and floating birds.

1, summer migratory birds

Summer migratory birds refer to birds that breed in a certain area in spring or summer, fly to warmer areas for winter in autumn, and fly back to their original places in the following spring. For example, Ru Yan, Rhododendron and Orioles are summer migratory birds in China.

2. Winter migratory birds

Winter migratory birds refer to birds that spend the winter in warmer areas in the south and fly to the north to breed in the next spring. Young birds grow up in late autumn and fly to their original areas for the winter. For this area, such birds are called winter migratory birds, such as geese, swans and wild ducks. Birds living in the middle and lower reaches of the Yangtze River in China are winter migrants.

3. Travelling birds

Refers to migrating through an area, but not breeding or wintering in the area. As far as this area is concerned, these birds are travelers. Migratory birds pass through some areas in the process of flying from one habitat to another according to different seasons, and do not breed in this area or spend the winter in this area. This migratory bird has become a tourist bird in this area.

4. Floating birds

Because of the relationship between climate and food, floating birds often move in different habitats. For example, blood pheasants inhabit Tibet, Sichuan, Qinghai, Qilian Mountain in Gansu and southwestern Shaanxi all the year round, and live in alpine shrubs, reaching an altitude of 4,500 meters near the snow line in summer.

In autumn and winter, they move to mountainous areas at an altitude of 2,000-3,000 meters for group activities, foraging for seeds, leaf buds, mosses and insects. Yellow-bellied pheasant is similar to blood pheasant. It is distributed in the southern mountainous area of Tibet, inhabiting the broad-leaved forest at an altitude of about 3000 meters, and it falls to an altitude of about 2000 meters in winter for small group activities.

The green woodpecker (Picus canus) is a resident bird all over China. It often lives in the mountains and forests in summer, and migrates to the plains and trees on the hillside in winter, drifting with food. Another example is the tit (Passer rutilans), which usually lives in mountainous areas, moves to Ye Ping in winter and moves in groups in the woods or farming areas.

Extended data

Birds that don't migrate are called resident birds. They live in the same place all the year round. They usually live in their birthplace (or breeding ground) all the year round. Introduction: Birds that live in breeding areas all the year round and do not migrate, such as magpies and sparrows.

Throughout the world, there are many species in the south, and the resident birds in the north are all cold-resistant species, such as grouse, Thunderbird and snow chicken. ) The resident birds in China are sparrows, crows, Chinese Pulsatilla, magpies, thrushes, osprey, woodpeckers and eagles. It is difficult for resident birds to find food in winter. Every winter, some resident birds live in groups.

Grabbing the fruits and seeds of plants as food. Birds that can be seen all year round in a certain place. Birds that live in an area all the year round and do not migrate with the seasons are called resident birds. They usually live in their birthplace (or breeding ground) all the year round.
