An auto-control bird-expelling device which functions independently and performs or suspends a bird-expelling operation in response to environmental change is disclosed. The bird-expelling device includes a detector and a bird-expelling signal generator. The detector automatically detects the environmental change, and informs of the bird-expelling signal generator to perform an bird-expelling operation when necessary. The environmental change can be the intrusion of birds into a designated range, and alternatively or additionally, can be the day and night change. On the other hand, the bird-expelling signal can be the sound of a fierce bird such as a hawk or an eagle, or any other visual or audio signals to drive the intruding birds away.
