Animals:

1, Crested Wheatcock, someone once put three small plates in front of the Crested Wheatcock, one of which put a small worm, one of which put two, and one of which put three. As a result, it sometimes ate the two first, and sometimes ate the three first. This experiment shows that the crested wheatear knows the difference between a large and a small number;

2. Crows, it has also been found that when the crows see the hunters with the guns, they hide in the tops of the trees and do not dare to fly down again. So four hunters hid in the hayloft in front of the crows. Later, one hunter was gone, but the crows did not fly down; two hunters were gone, and the crows still did not fly down; but after three hunters were gone, the crows thought that all the hunters were gone and flew down. This shows that the crow is smarter than the chicken, it can "count" to 3;

3, pigeons, foreign scientists have been in front of the pigeons put four identical box, the box lid were painted on a point, two points, three points, four points. In the test only four points of the box put food, pigeons eat the food, in the future test, it is always the first to open the four points of the box. This shows that the pigeon can "count" to 4;

4. The gray squirrel hides pine cones in many places before winter, and after that, it can usually find only six or seven piles of them, and then stops searching for the rest, which suggests that perhaps the squirrel can only "count" to 7;

5. This suggests that perhaps the squirrel can only "count" to seven;

5. A chimpanzee, a chimpanzee, takes 10 bananas at a time from a box. Once, scientists put 8 bananas in the box, the chimpanzee ate them all, and continued to look for them in the box, and the scientists gave it another one, but it still refused to go away, and must eat the full 10 before it would leave;

6. The ostrich, as the largest bird and fastest bipedal animal, has long fascinated mankind. But its behavior of sticking its head in the sand when it encounters a threat has become the most popular saying in the animal world. This is also known as the "ostrich tactic". However, this is not true. According to the World Wildlife Fund (WWF), ostriches react to danger by sitting on their nests and lowering their heads to the ground. As for the reason for this odd behavior, it has been suggested that this allows predators to mistake it for a termite mound or a lowland bush;

7. The pig is called a "miniature pig" in addition to its name. Its snout and four feet are white, and its body is black. You know why it is called fragrant pig? Because its meat is very tender and does not smell fishy, so it is called a fragrant pig. Its body is short, tiny, short and cute.
