There's a juvenile black bird in my parents garden and it doesn't seem to know what a blackbird is supposed to sound like. It keeps coming up with all sorts of weird noises that no bird before has ever made, but it is definitely just a stupid juvenile blackbird. It goes weeeeeeeeewop weeeeeeeeeeeeeeeeeeeewop weewop weeeeeeeewop

If there are any birdologists out there who can explain what the hell is wrong with it I'd love to know.
