If that is a mockingbird or similar, start to wear a hard hat (lock up the babies, kitties and old ladies too!) in your garage area, around here they don't take kindly to 'visitors' in their home when they have youngin's in the nest. Our two 'locals' have taken to defurring (dive bombing w sharpies) our old cat...if she wasn't so confounded at the sudden attack from up above, it would be hilarious.
