How to keep birds out of my yard without scaring away Hummers?
Is there any way to keep the Bluejays and Blackbirds out of my yard without scaring away my Hummers? These birds are loud and are dropping pecan and other nut shells all the place leaving a big mess! I do have a cat but I don't want her harming the hummingbirds. Even if I didn't have hummingbirds having a cat wouldn't help anyway because these blackbirds actually go after my cat! What can I do?
