Hello everyone, welcome to watch the science popularization pattern of this issue.
Speaking of African bison, everyone must know more or less, they are large, grumpy, even in the face of the continent's most powerful predator lion group, they dare to fight back, even if the lion herd encounters the bison herd, they will choose to temporarily retreat, the African bison is known by the locals as the most dangerous beast on the African continent, but it is such a grumpy bison, but only for a bird is very gentle, presumably everyone will find the African bison when they look at the animal world or man and nature, There will be a few small birds to stop, or even to peck out the wounds of the African bison, and the African bison will not have the slightest anger, why is this?
In fact, this bird is called the cow qiong bird, the cow qiong bird is not only not afraid of African bison, and even dares to drill into the nose of the cow to eat, so that the African bison does not have the slightest temper, in fact, this is because the cow qiong bird is helpful to the bison, because the cow qiong bird specializes in eating fleas on large herbivores and parasites such as blood-sucking flies and ticks, thereby reducing the burden on the herbivores, so the African bison is not only not annoying, but also very fond of the arrival of the cow qiong bird, although the cow qiong bird will peck out wounds on the bison, It brings some pain to the bison, but it will dredge the nose of the cow and eat the parasites in the nose and body of the cow, and it is said that the cow bird can eat a hundred blood-sucking lice and 13,000 larvae a day, and it is not an exaggeration to say that it is an animal doctor.
And sometimes the cow bird will also cooperate with the herbivores, for example, when the cow bird finds a carnivore, they will make a cry to remind the eating bison to help them escape the threat in advance, which is a warning effect, of course, not all the cattle birds are so kind, the cow bird will sometimes deliberately hurt the wounds of the herbivores, so that they produce more parasites, so that they have a steady stream of food, and even if the bison is scarred, it will deliberately peck and continue to produce parasites. And the cow bird can also spread the virus, causing the herbivores to grow skin diseases like small stones, of course, in any case, the cow bird and the ungulate animal cooperation, for both sides is still more beneficial than harmful, so we just need to look at the laws of nature normally.
