We had a one-eyed mockingbird hen nest in our yard. She was the best mom to her chicks, but she was so protective she would attack my dogs when they went into the yard to pee. It was the longest summer for them, with every trip outside a mission into enemy territory and constant dive-bombing! Poor dogs were afraid to go out at all after a while. I was glad when her chicks grew up and the nest was abandoned, and the dogs were very relieved too.
