Birds talk about birds
In terms of body size, the smaller the bird, the more it belongs to the big-headed monster
Birds are a magical species, they are the best creatures on Earth to escape the gravitational pull of the earth, that is, most birds are good at flying.
But the wonder of birds doesn't stop there.
This magic of theirs lies in their body proportions.
Unlike mammals or other animals, the proportion of birds varies depending on the species and size of their size.
The smaller the bird, the smaller the ratio of head to body, which became more pronounced after the bird's feathers were removed. The larger the birds, such as chickens and ducks, have a very large proportion of heads and bodies, and compared with their fat bodies, the proportion of heads is simply small and pitiful.
But the smaller the ratio of head to torso for birds of size, that is, the smaller the birds, the larger their heads.
The smallest bird in the world, the hummingbird, will be able to see that the head of the hummingbird is almost as large as the body when the feathers are removed.
The reason for such a miracle is mainly the need for survival.
Birds survive, more mainly the need for body warmth, so the body needs more and longer feathers to keep warm, and the head is more functional, the feathers are less and short, but this also makes the bird's head the most flexible, the most powerful part, small birds have a relatively large head, in order to produce the corresponding kinetic energy to meet the needs of daily foraging.
But the short feathers on the heads of small birds are not enough to withstand the cold at night, so most birds have long and soft necks, which can make them put their heads in the armpits or feathers on their backs when they feel cold.
