When a group of ducks walk, why do they always like to walk in line?

This is a very interesting question. Indeed, when a group of ducks walk, they usually line up in a neat line in a very orderly way, but as poultry, when a group of chickens walk, they will have no regularity and order. So, what caused the completely different habits of ducks and chickens? Let's discuss this problem together. First, let's see why ducks like to line up. Domestic duck is one of our most common poultry. Our domestic duck is domesticated from wild ducks. ?

According to the study of the remains of domestic ducks by archaeologists, it is found that the earliest domesticated wild ducks were domesticated by hardworking ancients about 6000 years ago. At that time, humans have domesticated many kinds of wild animals, including dogs, sheep, pigs, cows, cats, chickens, donkeys, etc. (in chronological order). As far as time is concerned, among all poultry, chickens are the earliest domesticated. About 8,000 years ago, after raising chickens for 2,000 years, people targeted wild ducks to fill their "egg bank" and "poultry bank". Therefore, many habits of domestic ducks can be found in their emerald wild ducks, including the habit of queuing. As a social bird, mallard ducks move in groups except for the breeding season. In the wild, wild ducks usually flock. ?

So, how is this behavior formed? We look at this problem from three angles: mallard is a widely distributed bird. Distributed in Asia, Europe and even America. As a kind of swimming bird, mallard always cannot live without water. The mallard mainly lives in open fresh water and feeds on animals and plants in the water. In the open water, wild ducks are completely exposed to the sight of natural enemies. When in danger, they like flocks of wild ducks. ?

If dispersed, it is easy to collide with natural enemies when taking off, which is not conducive to survival. If they line up, they can respond to emergencies in an orderly and safe way, even on land. On land, wild ducks also like to flock. On land, if carnivores such as foxes and wild cats gather together in disorder during hunting, they may collide with each other when taking off. Therefore, the orderly arrangement enables wild ducks to escape better in an open living environment without colliding with each other. ?

And this habit is also good for domestic ducks (mainly free-range), so domestic ducks have not given up this favorable habit. ? Ducks' habit of queuing comes from wild ducks, while mallard ducks have the habit of queuing and moving because, on the one hand, it is more conducive to their escape, on the other hand, they will soon establish a shadow-following star through learning after birth.
