Swallows fly south. In fact, some actually go to South Africa. This is the real Swallow South Africa, not just the south of our country. For example, ordinary floor swallows , which is Beijing Swift , will move to this South Africa. Those from the East will leave around July, first heading northwest into Mongolia, and then westward into northern Xinjiang, my country. , entered Central Asia from the Junggar Basin, crossed the Red Sea in about mid-August, arrived in central Africa in September, and then continued south, reaching the final destination in November, the South African Plateau, which is one thousand meters above sea level. The whole journey was 14,733 kilometers and took 111 days. In April of the following year, they returned to Beijing, a round trip of nearly 30,000 kilometers.
Some Beijing swifts can migrate up to 500,000 kilometers in their lifetime. This distance is more than enough to fly to the moon, which is equivalent to 12.5 times around the equator. Migratory birds including swallows usually bypass the boundless sea when migrating. They will fly over this land because they also need to rest on the way and need to eat and replenish fresh water. In fact, there are many types of swallows, and most of them choose to overwinter nearby. They are roughly divided into bird-shaped trees, mainly including the barn swallow, golden-rumped swallow, hairy horned swallow, and rock swallow, as well as common house swallows of swift wood, white kiln swift, and white-throated needletail swift.
In fact, most of the common swallows in life are barn swallows and golden-rumped swallows. These two like to build nests under the eaves of people. Barn swallows and golden-rumped swallows in eastern my country will fly to the southeast of Indochina. There are seven countries in Indochina, including Myanmar, Thailand, Laos, Vietnam, Cambodia, Malaysia and Singapore. These two kinds of swallows in Xinjiang will fly to South Asia. South Asia is mainly India, Pakistan, Nepal, etc. Some of these countries can fly to Africa. Hairy-footed Swallow is actually the same. Some rock swallows will stay in the north, and some will fly to the south of our country. For the remaining two types of swifts, some will stay in the south of our country, and some will fly to the Indochina Peninsula.
Swallows flying south do not go to the south of my country's Qinling Mountains and the Huaihe River line. Basically, they are a great migration across this country and region. Therefore, in the eyes of a swallow, the south is actually his earth, the south is actually the southern hemisphere, and the north is the northern hemisphere. The content of
