Among the common birds, the black capuchin bird can be said to be the most temperamental, if you accidentally provoke it, then it must not be finished with you, and it is not entangled with you for a while, but has been chasing you, if you do not change places to avoid it, then it will definitely compete with you for several years, the method used may be to peck the head with the mouth or pull on the head, although it is not very harmful, but the insult is very strong.

"Bird of Vengeance" black capuchin can be described as a veritable "Angry Birds", many friends know its rogue style, but do not understand its intelligence, in fact, this bird is not only difficult but also very scheming, some of the behavior is quite cunning, let's see how it pits its "teammate" mongoose in Africa.
Black capuchin is also called black iron fork, capuchin swallow, etc., this bird is not only in China, in fact, it is all over Eurasia and Africa, different places have different living environments, there are different animal partners, in the Kalahari Desert in southern Africa, it and the mongoose has become a "good friend"!
Mongoose, also known as foxes, swamp beavers, etc., is a small mammal living in the Kalahari Desert in Africa, the adult head and tail body length is only 40 to 60 cm, the weight is mostly between 500 and 1000 grams, mainly feeding on insects, mice, snakes, etc., which in turn live below the desert ground Scorpion, spider, centipede and other insects, mongoose is very good at digging holes in the ground to catch them.
Because the mongoose is small, many larger carnivores can catch it, so it has many natural enemies, such as foxes, jackals, hyenas, honey badgers, leopards, etc., but to say that it is most afraid of the eagle in the sky, because the eagle is best at launching surprise attacks from the air, as long as the mongoose does not pay attention, it may become the prey under the eagle's claws.
In order to avoid predators, mongooses choose to live in groups, usually dozens of living together, and burrow in the ground to avoid various predators, when foraging, at least one mongoose will stand up specifically responsible for the sentry, in the group it is the "mongoose sentry" on duty, other mongooses will be relieved to bury their heads in the ground looking for insects, but even if the mongoose sentry stands up, its height is limited, certainly not as wide as the black capuchin that stays in the tree or hovers in the air. Moreover, the sentry is better at finding predators on the ground and not good at observing threats from the air, and at this time, the black capuchin can help.
Whenever the black capuchin sees a fox, a jackal sneaking closer, or an eagle circling in the sky, the black capuchin will warn the mongoose sentry, the mongoose sentry receives the signal, the vigilance suddenly increases, it is easier to find the eagle in the sky and the fox approaching, then it will immediately scream loudly, the mongoose that digs the scorpion on the ground will immediately run to the cave when it hears the alarm, and it will safely escape the danger of being caught by the eagle or fox.
Seeing this, many friends may sigh that this black capuchin is really a good bird that is "helpful"! It can be called "the living thunder in the bird"! The black capuchin indicates that you don't dare to be! Shame on you! I just wanted to take advantage of the mongoose to run into the cave and find some small bugs to eat in the pit they had opened!
Don't care why, since you helped the mongoose to avoid the danger of being hunted by predators, it is also reasonable for the mongoose to harvest some bugs to eat in the pit opened by the mongoose, and both sides are repaying the favor! In this way, the black capuchin and the mongoose can also survive without worry, and it is not a problem to establish a tacit symbiotic relationship.
However, the black capuchin is not such a kind person, in its opinion, whether the mongoose can escape or not has nothing to do with it, it can only find bugs to eat from the pit that the mongoose has opened, so this guy began to use damage after finding his warning useful for driving the mongoose back to the cave - whenever it saw the mongoose digging some pits in the ground, it began to warn, regardless of whether there were predators coming.
The mongoose sentry is quite alert, and when he hears the warning of the black capuchin, he knows that things are not good, and quickly beckons everyone to rush into the cave, at this time the black capuchin will fly down and feast in the pit opened by the mongoose.
After this cool a few times, the pitted mongooses also came back to taste, thinking that you blackbird is a good teammate, I didn't expect you to be a pit cargo! What kind of eagle is there? I don't even have a hawk feather, and I want to take advantage of the big meal in the future, and there is no way!
As a result, when the mongooses were digging pits to catch insects, no matter how much the black capuchins sounded the warning, it didn't work! The mongooses are still buried in hard work, which can make the black capuchins bad, watching the bugs in the field being eaten by the mongooses one by one, angry black capuchins wow wow screaming, but this guy is not stupid, it found that the mongooses are particularly sensitive to the call of the mongoose sentry, as long as it gives an early warning, the mongooses will quickly run into the cave, hey, there is!
Only to see the black curly tail clear the voice, tweeting to learn the early warning sound of the mongoose sentry, the effect was indeed different, only to see the mongooses were suddenly excited, and the arrows off the string generally flew into the hole! The mongoose sentry still wondered, who is replacing my class? Black Capuchin didn't care about it, and flew down with great joy and ate again, a "master of deception".
In this way, the black capuchin did the work of a professional liar, whenever the mongoose dug the pit and dug vigorously, the rapid chirping of the black capuchin learning mongoose sentry sounded, which can be seen that revenge can only be regarded as a pastime when the black capuchin is fine, and deception reflects its professional and technical ability.
But after the mongooses were deceived a few times, they still found that they were calculated by the hateful blackbird, and they learned to distinguish the timbre of the black capuchin, although the black capuchin is the sound imitation master of birds, the imitation ability is no less than the pug who can learn to talk, but its timbre and the mongoose are still different, so the mongoose can gradually distinguish the timbre of the black capuchin, and it imitates the voice of the mongoose sentry.
When this happens, the black capuchin is not stupid, it will start from the beginning to find the eagle or fox to warn the way again, when the mongoose hears the warning of the black capuchin and is indifferent, the terrible predator suddenly appears, the mongoose is frightened or some of the mongoose is caught, and has to choose to believe in the black capuchin again, and the black capuchin can profit from it again.
The truth and falsehood of this made the mongoose suffer a lot, but it was already helpless against it, or that the mongoose had been subdued by the black capuchin, after all, the warning of the black capuchin was sometimes true, and this guy was flying in the sky, and the mongoose could not catch it and beat it, so it could only be done by it.
Don't underestimate the intelligence of animals, every species that exists has evolved for billions of years, and the survival wisdom it has is beyond our imagination.
