Swallows enter the home: Swallows were called "Yanzi" in ancient times, which means "purple gas comes from the east". Swallows build nests: Swallows build nests, which means "people are prosperous and happy". Swallow is a beneficial insect, which preys on the surrounding pests, thus protecting the nearby plants. Swallows are animals, and animals will have feces discharged and fall directly on the ground below the nest mouth; Animals will breed, swallows will hatch and there will be a little noise.
Swallows' nests are usually made under the eaves where people live, which can avoid the attacks of snakes and mice to the maximum extent and create a comfortable and safe environment for swallows. Where humans live, there are many mosquitoes and rich food sources; Walls and eaves can reduce workload and are stronger.
The material of swallow's nest is relatively simple, that is, soil, swallow's saliva and grass roots are mixed together. They fly to rivers and ponds, peck at wet mud, integrate it into particles, and then bring it back, mix it with straw and residual feathers, and build nests under beams or eaves. When building a nest, swallows build mud in the nest and squeeze mud balls from the inside out, so although the nest is uneven outside, the nest is relatively flat inside. The bird's nest is covered with light feathers, soft fur and fine debris, and it has become a very comfortable home.
To build a new nest, it will take at least 10 days, and the male and female swallows will work together to build a 3-4 cm mud wall. If the soil for nesting is not well obtained, or the beam is too smooth, a collision accident will occur, and all previous efforts will be in vain. At this time, the swallow will persevere, rebuild and build a new nest from scratch.
