The Hawk decoy is ideal for protecting open outdoor spaces such as backyards and gardens and is the first Hawk decoy available for deterring birds. Because Hawks hunt during the day, they are more recognizable as a predator than owls decoys. � How the Hawk Decoy Works: � Visual deterrents appeal to a bird's sight and sense of danger. Red Tailed Hawks are known for hunting during the day, while most owl species hunt at night when birds are roosting. This makes the hawk a more identifiable predator, when birds see the decoy; they will want to avoid the area!
