Interesting Information - Why do chickens always crow in the morning?
I don't know when chickens started crowing in the morning. As we know, the habit of roosters crowing in the morning is not something that is rarely found, but this habit certainly raises several questions and different assumptions in society. Just prove it !
RESEARCH RESULTS
A myriad of animal behaviors are generally driven by an internal clock in their bodies that recognizes time. For example, at night, some animals hide themselves in swamps or waterholes, even fish in caves use circadian clocks to tell the time.
“The sound of a rooster crowing is a symbol or sign that dawn has arrived. "Many people in various countries believe that, but this research is not clear enough to prove that roosters actually crow because they have a sense of time in their bodies or are just a response to stimulating external stimuli," said Takashi Yoshimura from Nagoya University.
Like turning on a car's headlights, it will trigger a rooster to crow at any time. This is also thought to be the reason why the rooster continues to crow because there is light pointing at the rooster. To find out, Yoshimura and his colleagues conducted research and placed 40 roosters in a setting with constant light, then recorded them crowing.
That's right, in fact the cock crows not only at dawn. Roosters also crow in response to light and as a way of communicating with other chickens, but their crowing behavior is much stronger at dawn. As a follow-up, the team hopes to determine the genetic underpinnings of other animal sounds.
Is it true that chickens have a biological clock?
Apart from finding that the biological clock is the main reason why chickens crow at dawn, the diligent researchers also discovered that the ranking system in chickens is a determining factor in when they should crow, because this crowing is also considered a warning that indicates a claim. each chicken's territory.
The data collected by the researchers also shows that the higher the ranking of a chicken, the more that chicken has the right to break the morning while the other chickens will patiently wait to follow the leader's crowing.
This research carried out by two young Japanese people sparked the research intentions of Kristen Navara, who is a hormone expert at the University of Georgia. Navara also added that research should have been carried out long ago which finally produced a biological clock as the answer, because this is the reason why roosters crow in the morning.
Hopefully this article can broaden your insight!
Do you like keeping chickens or like eating chicken? heheee
