Why does the rooster crow on time every day? It has an alarm clock. Can it time itself?

Zhou squatted in front of the henhouse at the top of his voice and learned to crow, so other chickens also crowed. This story is familiar to the older generation. It is the story of "Zhou Pipi crying at midnight". In the old society, there was a man named Zhou Pipi who hired some long-term workers to help him with his farm work. In order to let the long-term workers do more work, Zhou Pipi went to the henhouse early to imitate the cock crowing, in order to let the long-term workers get up early to work.

The long-term worker who worked in his house found out that it was Zhou Peeping who learned to crow, so he played along and took Zhou Peeping as a thief and gave him a good lesson. From then on, peeping Zhou dared not crow again, and peeping Zhou's chicken crowed on time. After listening to this interesting story, our question comes, that is why the rooster can crow on time every day. Does he have an alarm clock in his body? Can he tell the time?

In order to solve this interesting problem, in 20 13 years, scientists put 14 cocks in a closed room and conducted illumination experiments on them. First, these 14 cocks light 12 hours a day and turn off the lights 12 hours a day. The experimental time was 14 days.

However, the experiment continued. Scientists put these cocks in a closed dark room so that they can't see the light every day. In the first few days, the rooster could crow regularly two hours before dawn, but slowly the time moved back. If you give him more light, the rooster will crow, but the time is not allowed.

1. Why does the rooster crow on time every day? In addition to the above experiments, I also visited a chicken farmer who is familiar with the living habits of chickens. He told me why the rooster can crow on time every day.

He told me that the rooster crows at 4~5 am every day, just like setting an alarm clock every day. He told me that this is actually a "natural reaction" of the rooster, that is, the rooster crows under the influence of external light and the internal adjustment of the rooster itself, that is, at four or five o'clock in the morning, the light gradually increases in the dark, and the light is just like the alarm clock we usually give to the rooster.

Another important reason is that there is a gland called "pineal gland" in the cock's brain, which can be converted into melatonin by special enzymes. Melatonin is needed by both man and rooster. After melatonin, the rooster can sleep quietly, but with the stimulation of light, the melatonin in the rooster will decrease, so the rooster will have the desire to crow, and the rooster will crow on time with the enhancement of light.

Second, what are the signs of rooster crowing? There is another saying in the countryside, that is, when the rooster crows in the morning, we can say that it is the golden rooster that announces the dawn, which indicates that the fiery life of the day will begin again. But if the rooster crows at zero o'clock in the evening, which is what we usually call rooster crowing, what is the omen?

When I used to live in the countryside, I heard a rooster crow at 0 pm. In fact, nothing bad happened. According to the scientific explanation, when the rooster is illuminated by the moon at night, it makes the rooster think that it is dawn and begins to crow. In fact, this is a kind of "misjudgment" of the rooster. It can also be seen from here that light has a great influence on rooster crowing.

3. Why does the rooster crow? The rooster crows not only at night, but also during the day. The rooster crows at night, announcing the dawn and telling people that it is dawn. What is the rooster crowing for during the day?

Roosters crow during the day to declare their sovereignty. The higher the status, the first crow, and then slowly other chickens can keep up with the crow. There is also a rooster crowing to show his love to the hen, which shows that he is magnificent, and the more magnificent the rooster is, the more welcome it will be to the hen.

In short, from the above point of view, roosters don't have alarm clocks. The cock crows under the influence of light and its own pineal gland. Cock crowing is a natural phenomenon, but some crowing will also affect people's rest. Are you considering stewing or roasting this rooster at this time? What do you think is the main reason why the rooster crows? Welcome to exchange and discuss in the comment area.
