Birds would rather stand on the wires and get rain than hide from the rain, so why do they make bird nests? Why don't they hide from the rain?
When it rains, some birds do not shelter from the rain in their nests, but look up at the sky on power lines or branches.
Some people may wonder, why not go back to the nest?
Let's first understand the role of the bird's nest. There are more than 10,000 kinds of birds in the world, and the nests of each bird are strange.
Songbirds such as magpies, spotted doves like to walk simple pie I have no lid, Panqin tears like Chinese climbing birds, like to make a nest with doors and windows in the tree.
Nesting birds this bird world architect's house is complex, and can also be preserved for a long time in dry Namibia and South Africa. Bird nests are simple to manufacture, they are all made of licorice, mud, branches, etc., and they cannot withstand wind and rain at all.
It is better to shelter in the nest when it rains than to go outside to avoid the rain.
So why do birds nest?
In fact, they will build nests for their children during the breeding period, which is a temporary nursery.
Considering that the newborn baby bird is delicate and weak, the general bird father and mother will nest on the dense branches or eaves.
Some people may ask, if you don't shelter from the rain in the nest, where do you go to avoid the rain? This has to do with their body structure, especially feathers.
Bird feathers are a keratinized structure of epidermal cells, light and elastic, tough and suitable for flight.
Warm and waterproof birds are afraid of cold, in order to survive, flight must maintain body temperature at about 38.5 degrees.
To prevent the cooling caused by precipitation, birds must keep their feathers fluffy and warmer the looser they are. So when it rains, you can often see birds looking up at the sky at 45 degrees on the wires or branches, they are not using, but let the rain flow away from the body quickly.
The tail lipid glands in the tail of birds can secrete oil, and birds help each other and apply to each other's whole body, which is equivalent to putting on a raincoat on the body.
But if sometimes the weather is too extreme and the birds can't stand it on their own, they will ask humans for help, standing on the eaves or balcony, so don't drive them away at this time, don't be frightened, just don't see it.
