Get an Osprey for your pond. My son who was setting in a deer blind a couple of days ago watched the resident Osprey keep the Cormorants off the pond. It was pretty cool thing to see. He would dive bomb and fly over the pond, any Cormorant that was looking to land at the pond he would drive it off. The way I look at it is one Osprey that eats fish is better than several Cormorants that eat the fish.
For the past few years an Osprey has shown up as the water temps cool down and when the Tp start swimming at the ponds surface looking for some warmer water. I expect the Bald Eagle to show up soon if he is not already there. He also shows up around this same time of the year,
