Silly question - I have water turkeys land on my pond in Texas this time of year - I started running my 4 aerators during daylight hours and have not had one of them come in since I started. I know they do not like movement but could the water movement from these aerators be spooking them from landing?

I suppose it's possible, but only if the aeration system is causing a thorough disruption of most of the pond's surface. This would make seeing into the water very difficult for hunting their prey. My small pond has excessive aeration (1/4 acre with 3 diffusers) and it does nothing to thwart the Great Blue Herons.

Disclaimer: I live far enough north that cormorants are non-exist ant, so I know little about them.

diffused ait has never kept cormorants off my pond. the best control I have found is to send my retriever in the water to get them off the pond. The second best is to fire off a shotgun but that might not be legal.
