It is not a good idea for a blackbird to nest on a windowsill. First, blackbirds building nests may cause damage to the environment around the windowsill, such as damaging windows, walls, etc.
Secondly, birds may be injured or killed because their nests are unstable. It can cause accidents to happen to the nest, and there is a greater risk of hatching and caring for the young. In addition, nests may interfere with the use and opening of windows. Therefore, in order to protect the safety of blackbirds and themselves, it is best not to let blackbirds build nests on windowsills. If necessary due to special circumstances, the safety and stability of the nest should be ensured, and the nest should be cleaned and disinfected in a timely manner.
