What is the reason why the cock crows?

The cock crows because of the biological clock.

It turns out that roosters, like humans, also have a biological clock in their bodies, and their life activities have an inherent rhythm, which is determined by the time structure order of the biological clock itself.

Chicken eyes are very sensitive to light. Generally, chickens are night blind at night. Before dawn, some faint light was perceived by the rooster in advance, just like receiving a signal, which made the rooster extremely excited and instinctively crowed.

Chicken is a highly socialized animal, and crowing is also a way to warn its territorial boundaries, thus avoiding fierce conflicts.

When the cock crows

As the saying goes, "the rooster crows at midnight and the dog crows at dawn." Midnight is midnight, also known as midnight and midnight, which is 1 1 to 1. The time of the first cock crow is about 0: 30 am to 1, with an interval of about one and a half hours. At the third cock crow, it will be dawn, which is different in different seasons, around three o'clock in summer. It's about 4-5 in winter.

Chickens are gregarious animals, and there are always many family chores to deal with if they are polygamous. Especially as parents, roosters have to shoulder many tasks of commanding and making decisions.

For example, if a rooster finds food, he will ask his wife and concubine to share it. If earthworms or beans are found to be so delicious, their barking frequency will be higher; On the contrary, it will crow less frequently, so the cock will crow loudly.

After thousands of years of evolution, this cry has formed the habit of crowing in the morning, which is the function of the biological clock, so every morning, you can hear the cock crowing in the country.
