Poems about swallows making nests at home include: Spring swallows build their love nests with mud in their mouths, working hard and not afraid of hard work. Settling down under the eaves to take shelter from the wind and rain, and the love has no boundaries to nurture the seedlings. Swallows are beneficial birds to humans. They mainly feed on insects such as mosquitoes and flies. They can eat 250,000 pests in one season, so we should protect them.
Swallows' nests are usually built under the eaves of occupied houses, which can avoid attacks by snakes and mice to the greatest extent and create a comfortable and safe environment for the little swallows. Where humans live, there are more mosquitoes and abundant food sources. Walls and eaves can reduce the workload and are relatively strong.
