I have a panel van with the black glass sides. It’s parked under a car port about 15 inches from a 10 ft laurel hedge. Last weekend it came under a three day attack from a male blackbird which would fly out of the hedge and attack its reflection. Didn’t seem to get bored. Been away for 3 days and since return there’s a blackbird around on ground near van, but no attacks. Not seen a bird go for it’s reflection for so long before
