Rivers with blades of grass and waving sparrows are:
Quiet sparrows and winding rivers
< p>Sparrow (Passer): This is the collective name of 27 species of small birds of the genus Passeridae. Their size and body color are very similar. Generally, the upper body is mottled brown and black, which is why it is commonly called a sparrow.There are 9 primary flight feathers. The edges of the light-colored feathers of the outer flight feathers (except the first) are slightly enlarged at the base and proximal end of the feathers and are interspersed with each other. , forming two horizontal spots, this is particularly visible in flight. The mouth is short, thick and strong, cone-shaped, with a slightly curved tip. With the exception of tree sparrows, males and females have different colors.
There are 27 species in the world, of which 5 aret distributed in China. The distribution is quite wide. Except for the extremely cold deserts of the Arctic, Antarctica and high mountains, it is widespread throughout the world.
River (River): Refers to precipitation or water that emerges from the ground to the surface and accumulates in low areas of the ground. It is caused by the flow of. water itself frequently or periodically under the action of gravity.
There are different principles for classifying rivers. They can be divided into inland rivers and outlet rivers based on their injection points; inland rivers flow into inland lakes or swamps, or disappear into the desert due to infiltration and evaporation. ; outgoing rivers injected into the ocean. The rivers of China are often classified based on annual dynamic differences in river runoff and are divided into seventypes: Northeast, North China, South China, Southwest, Northwest, Inner Mongolia and Tibetan Plateau.
China has 50,000 rivers with a drainage area of more than 100 square kilometers, of which the Yangtze River is 6,397 kilometers long, making it the third largest river in the world. Areas with dense river networks. the world is often located in areas with a humid climate, such as in the Amazon lowland, the Amazon River in this region is 6,480 kilometers long and is the largest river in the world.
When a sparrow sleeps, one side of its brain is asleep and the other side of the brain is awake.
Scientific research shows that the sparrow is a bird exhibiting a phenomenon of “unihemispheric sleep”. When a sparrow sleeps, half of its brain goes to sleep while the other half stays awake. This way of sleeping allows the sparrow to remain attentive to the environmentoutside during its rest, in order to detect potential threats in time or to maintain its ability to fly. This particular sleep rhythm has also been observed in certain birds and marine mammals. Through unihemispheric sleep, sparrows can balance rest and protection based on their lifestyle and survival needs.
