Yes, predator decoys work to keep birds away, at least temporarily.

Woodpeckers peck at the break of dawn and take a break whenever the sun is not shining. On sunny days, expect pecking from dawn to dusk. On cloudy days, expect sporadic pecking when the sun peeks through. These birds are most active in the spring; you’ll hear them drumming as soon as the weather turns warm. 

Hawk attacks on pets are rare, and they won’t target animals that outweigh them. Hawks typically weigh between one and three pounds. That means you don’t need to worry if you have a Labrador Retriever or French Bulldog. However, small cats and toy breed dogs, like Chihuahuas, are at risk. Pet attacks are more likely in winter when food is scarce or in the early summer when inexperienced young hawks are honing their hunting skills.
