I have the same problem with the genus corvidae. As far as crows and rooks go, I cling to the belief that if you see one rook it's a crow, and if you see a flock of crows then they're rooks, but jackdaws have me flummoxed (I'm not sure I've ever even seen one). Ditto ravens. Thank heavens for magpies, and it's not often you hear me say that.
