Many animals have the ability to surpass human beings. Even in distant places, they can tell the direction and find their way home. This is really amazing! You see, that little bee can fly away from the hive for thousands of meters to collect nectar, and never get lost again when she gets home. Someone once took some bees out of the hive, marked them, put them in a box and took them far away before releasing them. These bees circled once or twice in the air and soon flew back to their original hive.
Many fish can swim much more than bees. Their long-distance travel is not only long and time-consuming, but also seasonal and regular. In early summer, China perch went upstream from the offshore to the estuary, and did not return to the offshore until it laid eggs in autumn.
The ability of birds to travel far is even more amazing. As early as more than 2,000 years ago, human beings have used pigeons to pass books. The pigeon that flew farthest once flew over Eurasia from France and returned to Vietnam. Pigeons were kept in a cabin and taken to a strange France. Maybe you will say that pigeons are raised by people and are usually trained. However, although swallows have not been trained, their ability to go home is no less than that of pigeons. Someone caught seven swallows in Germany, let them fly near London, England, and then set them free. The distance between the two places is more than 1000 kilometers, and five swallows actually flew back to their hometown.
Animals often have to overcome many obstacles in their long-distance migration. Their patience and perseverance are admirable! After salmon was born in the river, it swam downstream to the ocean. After living in the ocean for one to three years, they return to their hometown in droves to lay eggs. When they swim upstream in the river, they jump desperately, which often makes them scarred and even scales fall off. However, they kept going until they reached their destination.
In addition to amazing patience and perseverance, the ability of animals to find their way is really amazing. Take the nightingale for example. Winter is coming. When birds fly to the south, their feathers are not full. Once their wings grow, they can naturally find the direction of long-distance travel and fly to places they have never been to for the winter. Biologists are still studying these strange phenomena and have not fully found the answer.
The mystery of nature is really puzzling!
