What does it mean when a bird keeps knocking on my window?
The frequent pecking of birds at the windows is no accident. They may be looking for help, for example: condensation on the windows blocks their view, or there are substances attached to the windows that are difficult to remove, preventing them from feeding or roosting. It could also be that they are expressing discomfort with their environment, such as a lack of suitable habitat or food sources. Don't ignore it, watch carefully, and try to improve the environment to really help the bird.
