In the minds of many farmers, the yard coming to their home must be a symbol of good luck. Therefore, although swallows are twittering, they will not be driven away, but they are very welcome. Moreover, people will not destroy the nest where the swallows live in 1 year, so many swallows may find traces of the past and return to the familiar environment. Swallows also have their own temper and disposition. On the way back, if the bird's nest where they once lived gives off the smell of other birds, the swallows will leave in time. Because this means that this nest is no longer suitable for them, they are also very afraid that these birds will come back and affect their normal life.
Spring has come, the temperature has warmed up, and the swallows have basically returned to the south. You can observe that some swallows also get old, so they become familiar old swallows. Most old swallows may return to their nests in 1 year. If it is their son or daughter, they will choose to nest again, because they also need to continue to reproduce.
Swallows also have their own choices in choosing a suitable place to live. They also need to go out for food during the day. At the same time, it is necessary to provide a safe and quiet environment for the baby. So most people prefer tall houses. If the family members are friendly to themselves, I believe they will remember. At the same time, they will choose a quieter environment. If the house is noisy all day, the swallows will be uncomfortable. If there are swallows at home, they need to be cleaned up in time.
