Many cats chirp, creating a chattering sort of sound, especially when watching birds or squirrels outside their windows. Behaviourists believe that these sounds are driven by catsâ unquenchable hunting drive.
Sound bird deterrents use birdsâ instincts to scare them away from large open spaces. Recorded bird-distress calls are broadcasted along with predator bird calls; when birds hear these sounds, their natural instinct is to flee the area. Birds hear sounds in the same range as humans. This makes sound producing Super Sonics the only effective choice for electronic sound deterrents.
