How ferocious can a bird the size of a palm be? But the Burrow bird has this skill, and the name "ferocious" has been hanging on top of its head for thousands of years.
Judging from the appearance of the Bird of Berlau, no one can believe that this is actually an executioner. The furry flesh of the body, the color is also warm orange, the palm is so big, it looks like a larger house finch. But cute love, how can it be hung up with the ferocity?
The Burrow bird has always been known as the "butcher bird", and as soon as you hear the butcher, you know that it must have nothing to do with meat. As a bird eating meat is also normal, small finches like to peck at the millet and like to eat bugs, The berau bird is a few sizes larger than the small house finches, and it is certainly not okay to eat fruit millet, and the staple food is definitely meat.
Meat-eating birds are common, and the uncommon is the way the Burrow birds eat meat.
If one day you find a grasshopper strung on a thorny branch on the side of the road or a barbed wire on the side of the road, or a gecko, a frog, etc., you may think which child is playing a prank, this child killed animals at a young age, and grew up to pay back?
Now you have to have another idea, this is the Berau bird dried, do not know if it can eat it or not.
See, if it's done by man, it's suspected of killing animals, and in fact the Berlau bird often does this kind of thing, wearing prey on branches to make meat skewers, and it's no wonder people say that it's murderous.
This kind of behavior of hanging prey on branches, barbed wire, and spikes, especially like a butcher hanging meat, hence the name "butcher bird".
Just after the New Year, have you missed the bacon at home, and have you found that this practice of the Berlau bird is similar to making bacon. The behavior of the Burrow bird by hanging its prey on a branch is similar to the original intention of everyone to make bacon – it is easy to store.
The Burrow bird is also bitter in using such a ferocious method, although it is quite fierce, and its combat effectiveness is quite impressive, but after all, it is a small bird, and it cannot be compared with the big bird like the goshawk. When the goshawk is a big bird when hunting, its claws can catch the prey in mid-air, and after catching it in mid-air, it is easy to say, whether it is thrown to the ground and fall to death or caught back in the nest to bite to death, as long as there is no other animal to grab it, it is definitely it.
The berau bird's claws are not as strong, but its beak is similar to that of an eagle, with hooks.
When the Burrow bird catches prey, it can use such a bird's beak to bite off the throat and spine of the prey. Of course, this is not enough to make the prey die thoroughly, so they will shake their heads wildly, like a dog throwing water on its own body, using this amplitude of swing to accelerate the death of the prey.
Sometimes, the Burrow bird takes its prey directly to a spike and crosses it to the chest, assisting it in killing its prey in this way.
After that, the Burrow birds will skewer "meat skewers", they hang their prey on spikes. Because their claws are not so strong, they can only tear off the meat with their beaks and eat them.
Other birds basically have something called a sac to store food, and they can eat it when they are hungry, but the Burrow bird does not have this structure, that is to say, the Burrow bird does not have an organ to store food.
Hunting and flying are huge energy consumptions, so birds generally eat all day long. The Burrow bird has no storage structure, so it has only two choices, either to find a place to store, or to hunt non-stop to replenish energy.
The Burrow bird chose this "skewered meat" method to store food, which also avoided other animals living on the ground.
Of the known birds, only the Burrow bird does this method, and the other birds either find food and eat it immediately, or take the inexhaustible ones to their holes and hide them. The method of the Burrow bird is more clever than that of bringing it to the cave, avoiding both other animals from snatching it and the decay of its prey.
Although it is not a big deal for birds to eat some carrion, but there are fresh people who are not willing to eat bad, berau birds nail their prey to the branches to make "air-dried meat", which is a good way to avoid the rot of meat.
Moreover, in the food of the Berau bird, there is a poisonous grasshopper, and the grasshopper hangs on the branch for two days after the toxicity is gradually decomposed, and the Burrow bird also avoids poisoning.
In addition to this, the hanging prey also adds chips to the courtship.
The Burrow bird is also a monogamous bird, and when they court, a string of prey hanging from a tree proves how capable it is. Burrow birds also imitate hunting and nesting, feeding their prey to their mates to prove that they can take good care of each other.
I have to say that this way of courtship can be compared to other birds when courtship to dance a fancy dance is really much more, no wonder the Berlau bird can be a pair of birds in a lifetime, people have tested each other's ability before marriage.
Not only that, after the female lays eggs, the male will take care of the child with the female, rather than like most of the male birds in the birds, just give birth to the wife and not care about the wife.
From this point of view, the Berlau bird is still a good bird.
As for their cruel behavior, it is also a necessary condition for their survival. Hyenas hunt when the method is also very cruel, some foxes will peel off the skin of the prey alive is also cruel, carnivores in order to ensure their survival, which is not cruel? These are all necessary means of survival.
