Mockingbirds are notorious for guarding thier territory -- especially when the eggs and babies appear. The dogs and cat are going to be for lots of dive bombing attacks and will eventually learn to only exit the house via the back door. We too will probably have to exit and enter through the laundry room door. On the plus side, they will probably keep away folks I really don't want to see.
But what if they attack the UPS guy? Will he quit delivering packages? This could be a disaster! What about all my yarn and roving orders? I may have to leave him a note warning him. Perhaps I can call his office and let them know that he should come to the back door and leave the packages on the well cover.
