Tianfu natural calendar 丨 Sparrow is a bird?This is a misunderstanding!(July 19)

"The sparrows outside the window are talking on the telephone pole. You say this is a very summer feeling ..." The sparrow is one of our most familiar birds. Their screams are the most common background music of summer.

In the past, the "reputation" of the sparrows has not been very good, and it has even been listed as one of the "four harms" (rats, sparrows, flies, mosquitoes) -this is because when the grain is mature during the autumn harvest, people always watch it. The sparrows who fired in the group flew to the farmland to eat grains.

In fact, sparrows are omnivorous birds. In winter and early spring, the sparrows are eaten with the seeds of weeds and wild grasses, and they also eat various foods thrown by humans. Xia and Qiu mainly use the seeds of the grasses as the seeds, and the youngest period mainly thinks that the insects that harmed the gradient plants are mainly lumper -winged pests. It can be seen that the sparrows are not harmful to the crops. In the summer and autumn seasons, the mature seeds do not stay in the field for a long time, and they will soon be harvested.

Today, the sparrow has been renamed: it is included in the "Land Wild Animal List of the National Protection or an important economy and scientific research value" released by the State Forest Cao Bureau. The acquisition of sparrows is illegal.

At the same time, as a large number of wild animals, the sparrows have a very important position in the natural ecology. Once their quantity drops sharply, it will inevitably cause the fluctuation of the food chain and affect other creatures.

The altitude sparrows of sparrows are large, 300-2500 meters. No matter the mountains, plains, hills, grasslands, swamps and farmland, they have their traces. The sparrows are very lively, bold and approachable, but they are very vigilant, and they are very curious.
