The night before last, dh and I were sitting on the back patio, enjoying the evening air. It was pretty dark, but we have some "moonlighting" in the trees near the pond, so we can see pretty good in the back yard around the pond area. In a flash, one of the great horned owls that lives in the area swooped in, pulled one of my koi out of the pond (the koi is was about 13" long) and flew off. This happened not thirty feet in front of us! He came back last night, but dh shot the 12 gauge in the air and he flew off. Help! I bought a bobble head hooting motion sensor decoy today, but after thinking about it, will that encourage the owl to come back thinking he has a friend at the pond? Has anyone else had owl problems?
