Why are there more crows in the city now?

Crows are scavengers, they will find the corpses of animals and people, and often go together to peck at their flesh, because they are like death, giving people a sense of foreboding, so many places will use crows as a symbol of bad omen. The black body of the crow makes people feel frightened, and the large number of crows gathered represents the arrival of the changing sky and some natural disasters, which adds to its bad impression in people's minds.

The relationship between the crows of the city of Beijing and the Manchus:

In fact, before the Tang Dynasty, the crow represented the auspicious and prophetic sacred bird in Chinese folk culture.

The origin of the Qing Dynasty's Aixinjue Luo clan is related to crows.

According to legend, there is a Bukuli Mountain in the Northeast Changbai Mountain, there is a lake on the mountain, called Bule Huli Lake, the scenery here is beautiful, very pleasant, one day, there are three fairies come here, the eldest is called Engulun, the second is called Zhenggulun, the third is called Fokulun, see the lake is very beautiful, so play in the lake, suddenly fly a bite of the crow magpie with the Zhu fruit, and it just falls on the body of the Verculun, and Fokulun sees the fruit is very appetizing, so he eats it, but is therefore pregnant, After October, he gave birth to the ancestor of Aixinjue Luo, Bucuri Yongshun.

The relationship between Aixinjue Luo and the crow is more than this, many years after Bucuri Yongshun, the strong Aixinjue Luo clan rebelled, and finally only one descendant named Fan Cha was able to escape, but in the face of countless pursuers, Fan Cha can no longer run, and he is about to be caught up, at this time the crow magpie appeared again and fell on his body, the pursuers mistakenly thought that the crow magpie fell on the dead tree, and he really couldn't find Fan Cha, so he had to go back, Fan Cha escaped, and also kept the last bit of blood in Manchuria.

On the contrary, the crow is a scavenging bird, a garbage dump for humans, providing it with a lot of food! It is the result that it reproduces in large numbers. At the same time, human activities have reduced the natural enemies of crows, and there will be more and more crows!

Crows have the habit of swarming, because the temperature in the city is relatively high, so some crows living in the suburbs are concentrated in the city for the night, and fly back to the suburbs to forage during the day, so people in the city often see a large number of crows in the early morning and dusk.

In winter, because of the lack of food, there is a habit of swarming, the number is very large, and sometimes it can even reach tens of thousands, and the collective action that covers the sky and the sun is particularly spectacular.

HabitatIt inhabits low mountains, plains and mountain broad-leaved forests, mixed coniferous and broad-leaved forests, and coniferous forests.

Among various forest types such as secondary mixed tree forests and plantation forests, sparse forests and forest edge zones are more common.

He prefers to be found along forest roads, cliffs, river valleys, coasts, farmlands, marshes and meadows, and sometimes even in mountaintop scrublands and alpine tundra areas. However, in winter, it mostly goes down to low hills and plains at the foot of the mountains, and is often found near farmland, villages, and other places where people live, and sometimes in town parks and urban trees.

Maybe it's the migration of birds. Nothing else ...

The crows foraging for food must be looking at the slaughterhouse! The sense of smell is strong!

The smell of decay will attract crows.

Crows like to live in groups, strong clustering, a flock can reach tens of thousands of things. It is a forest-steppe bird that lives in groups in the woods or in the fields, foraging mainly on the ground, and has a steady gait. With the exception of a few species, they often nest in groups and wander in groups in autumn and winter.

Complex behavior, showing strong intellectual and social activities. Generally fierce and aggressive, it often preys on the eggs and chicks in the nests of waterfowl and wading birds.

Some caged crows for pleasure "talk", and some lab-raised crows learn to count to 3 or 4 and find marked food in boxes.

Omnivorous, eating grains, berries, insects, carrion, and eggs of other birds.

Many species like to eat carrion, and have certain harm to seedlings and grains.

However, during the breeding period, it mainly feeds on small vertebrates, locusts, mole crickets, golden tortoise shells and moth larvae, which is beneficial to agriculture.

In addition, because it likes to carrion and peck at agricultural waste, it can eliminate the pollution of the environment such as animal carcasses, and play a role in purifying the environment.
