There is a scene in Animal World in which a male black bear shakes a wooden stake in front of the opposite sex. Can you guess why it does this? It turns out that this male black bear is trying to please the female bear and show his strength. This behavior belongs to the courtship and ostentation of animals.
Speaking of courtship and showing off, birds can be said to have many means. Among them, a good dancer can sing and dance, and a good dancer can sing and dance. Especially in the case of competition between two males, whoever sings more beautifully and dances more beautifully will eventually win the "heart" of the female. In some birds, the male only needs to show beautiful feathers, and the female will be emotional. The male peacock impressed the female peacock with a beautiful tail screen. Some birds will put on bright feathers before they get married. Once the breeding season is over, the wedding feathers will be replaced.
The most interesting thing is that some animals even choose "family" and "bride price" when looking for a mate. There is a bird called "Forty Birds" in finches. The female of this bird should first choose the male who lives in the rubber forest with rich food, and ignore the male who lives in the willow with poor food. Some animals must bring gifts when courting. Adelie penguins live in the Antarctic, and males have to choose some pebbles as gifts before courtship, which is hard to find in the frozen Antarctic. Among insects, there is a long-legged mosquito. Only when the male brings a big and delicious bug does the female agree to mate with it.
Besides birds, other animals also sing "love songs" to make love. Male frogs make the loudest noise during the breeding season in order to attract nearby female frogs. In summer, cicadas in the trees are always chirping. These chirping cicadas are all males. They sing loudly to attract females to mate.
Some animals, such as moths among insects, even communicate with each other by smell. Female insects can secrete a special chemical called sex pheromone. The smell of this substance can attract males far away.
Not all animals are so civilized when courting. Some animals have to resort to force to compete for females. The winner gets a spouse and the loser gives up. Male elephant seals fought bloody battles with other male elephant seals because they wanted a female elephant seal. After the battle, the winning male elephant seal will drive away the defeated with its female elephant seal. For all kinds of horned animals, their horns are very useful in battle. Therefore, the male who is big, strong, strong in courtship signal and can provide the best territory becomes the ideal partner of the female.
Through the choice of spouse, the outstanding individuals in the race have the priority to reproduce, which is of great significance to maintain the quality of species.
