Why are there so few swallows in 2024?
The low number of swallows in 2024 was the result of a combination of factors. In terms of housing, with the advancement of the city's development, many old houses were demolished or renovated, changing the original structure suitable for swallows to build their nests. For example, the windows were sealed and the eaves were installed with protective nets, making the swallows lose their nests. At the same time, high-rise buildings, utility poles and other construction facilities also became obstacles for swallows to build nests. Even if humans built nests on the eaves of buildings to keep the swallows, compared to the natural environment in which the swallows grew, such an environment had a lot of restrictions on the growth of the swallows. In terms of food supply, agricultural production methods were constantly upgrading, and the use of pesticides increased. This destroyed the ecological environment of the farmland and drastically reduced the population of beneficial insects that many insect-eating swallows could feed on. Moreover, after swallows ate insects with harmful substances in their bodies, their physiological health was affected and even their lives were endangered. In other aspects, the swallow faced more competitors, such as sparrows. Sparrows would occupy the nests of swallows. Swallows were not good at fighting for territory and resources. They could only give up or be forced to choose places that were not suitable for nesting, affecting their survival and reproduction. In addition, during their migration and wintertime, swallows would be affected by natural factors, such as bad weather and sudden drop in temperature. The number of swallows that died due to natural factors during the wintertime accounted for a high proportion of the entire population. In addition, in some areas, swallows were listed as harmful birds and were hunted, which also led to a decrease in their numbers.
