Do Fake Owls and Other Decoys Work?

A study by Linfield College found that songbirds are afraid of owl decoys. Researchers swapped out owl decoys for a cardboard box of the same size in an oak woodland within Oregon's Willamette Valley. Then they measured how often birds visited feeders in the vicinity of the objects and found they were much less likely to go near the feeder when the owl decoy was stationed nearby; however, they weren't scared one bit by the cardboard box. The birds did wise up over time, though. After a few days, they realized the owl was fake and returned to the feeder.
