Talking about what are resident birds and migratory birds from "When did you notice the swallows were missing"

Have you ever noticed that the barn swallows flying around you started to disappear?

Why do we always go to Sanmenxia to see swans in winter?

But sparrows, magpies and gray magpies will chirp overhead all year round.

This is about talking about resident birds and migratory birds.

We know that birds have the habit of migrating as the seasons change, and resident birds and migratory birds are divided accordingly.

To put it simply, birds that can be seen in a certain area all year round are resident birds. For the Zhengzhou area, in addition to the above-mentioned three swordsmen (sparrows, magpies and gray magpies), common resident birds include blackbirds (dōng), turtle doves (mountain turtle dove and pearl-necked turtle dove), hoopoe, white-headed bulbul (bēi), common Kingfisher and more.

The migration of migratory birds is regular, twice a year, once in spring and autumn, so they are divided into summer migratory birds and winter migratory birds.

In layman’s terms, a bird that can only be seen in spring and summer in a certain area is a summer bird for this area. For example, barn swallows, black drongos, the great cuckoo, and the cliff sand swallows that make the news every year. They breed and raise chicks here, and when the weather gets cold, they fly to Southeast Asia or even further to the southern hemisphere to spend the winter.

What can be seen in autumn and winter are winter migratory birds. In Zhengzhou, if you go to the Yellow River, Longzi Lake, Beilong Lake, Yanming Lake, etc., you will also have the opportunity to see swans and various geese and ducks. Last year, the critically endangered blue-headed pochard appeared in Longzi Lake.

In addition to resident birds and migratory birds, there are also birds called transit birds (also called migrant birds), which are birds that stop briefly in a certain area during migration. In May last year, dozens of species of passing birds were observed in a small tree at a university in Zhengzhou, which was a feast for the eyes of bird lovers.

When you step into the world of birds, you will find that nature hides so many incredible things.
