oh i forgot to mention great horned owls decimate hawk populations, falcon populations also osprey. They just ruthless. They often get hawks at night but can clear the area of them.
depends on the owl the great horned owl is the only serious predator so are snowy owls but i doubt they would be around where u live. barred owls are more concerned with rats and rodents.
THe other owls are really small.
owls are night predators if chickens are locked up they will just eat the predators that the chickens attract. Good bird to have around. I use their statues to scare animals. It only works if i keep moving the fake owl around though.
center have you noticed a decline in predators with owls around?? i wish we had more. I saw one kill a mink. ANother one killed a skunk. I also read they will kill adult coons large snakes weasels.
