Price: £294.48 Bird X-Peller Pro

The Bird X-Peller Pro is a distress call scaring system with a built in speaker.

The new sonic repeller from BIRD-X that uses different birds' own distress calls to create a "danger zone"; which effectively frightens the infestation flock away.

Proven and Tested. In extensive field tests, BirdXpeller Pro has significantly reduced, or entirely eliminated infestations of sparrows, pigeons, robins, finches, starlings, blackbirds, gulls and other species.

How it works:
BirdXpeller Pro takes very high fidelity recordings of birds' distress cries. The resulting sound is so faithful to the original that they cannot be told apart! The infesting birds perceive danger when they hear these sounds, become agitated and disoriented and flee the area... not to return.

Species specific... and programmable! The BirdXpeller Pro attacks pest birds, but it is totally benign: it will neither kill nor harm the birds. Choose the sounds of the birds that are invading your space! If you add predator calls to your program, you'll give the birds even more of a sense of danger.
