When will Yaan Seagull fly away?

Yaan seagulls will not leave until around May. Migration of migratory birds is a natural law of bird life. 165438+ Every year from the end of September to the end of 10, some seagulls near Siberia and Zoige will migrate to the warmer south for winter, and then migrate to the cool north for breeding and summer vacation in May of the following year.

During the passage, they will make a short stop and rest to replenish their energy. Year after year, seagulls live and multiply in this way, which is closely related to their physiological characteristics and living habits.

Habitat and living habits of seagulls

The breeding season mainly inhabits rivers, lakes, ponds and swamps in open areas such as Arctic tundra, forest tundra, desert and grassland, and mainly inhabits coasts, estuaries and harbors in winter, and the migration season also occurs in large inland rivers and lakes.

Seagulls are the most common seabirds, which move in pairs or groups of three or five or fly in the air. In the seashore, seaport and fishing ground rich in fish and shrimp, they float on the water in groups, swim for food, fly low, and like to cluster in the food-rich sea. Seagulls feed on coastal insects, mollusks, crustaceans, worms and grubs in cultivated land, and also prey on small fish on the shore, picking up leftovers discarded on the shore and on ships.

Sometimes they prey on other birds' eggs and young birds. If seagulls fly close to the sea, the weather will be fine in the future. If they wander along the sea, the weather will get worse gradually. If seagulls leave the water and fly high, flying from the sea to the seaside in droves, or flocks of seagulls gather on the beach or in cracks in rocks, this indicates that a storm is coming.

Seagulls can foresee storms because their bones are hollow and tubular, and they are filled with air without bone marrow. This is not only convenient for flying, but also like a barometer, which can predict the weather changes in time. In addition, the hollow feather tubes on seagulls' wings can feel the change of air pressure sensitively, just like a small barometer.
