This morning I was outside with our cat Oscar when I heard a familiar bird that landed on our fence along with this young female. Have not seen the adult male mockingbird in a few days. He taught his young male bird well as he sounds just like him and seems to act the same way too. Have no idea if this is his sister or partner, but happy to see these young mockingbirds. He did not dive bomb or go after Oscar. Both flew up into the tree after this.
