Last year crows began coming to our backyard. I had a 24" diameter bird bath that the cardinals and blue jays loved. The crows have scared them away. We emptied the bath but the crows are still in the neighborhood. Is there any way to keep them out of our yard so the other birds will come back?
Often, using predator urine such as fox, or coyote can help prevent these from coming around as often. Alternatively, getting a dog will keep them away! It can be difficult to deter them, so you will have to use something that they are afraid of.
