Jackdaw would be smaller, with a noticeably grey head and a small, pale eye. In contrast, Raven would be much bigger, with a really heavy bill, long feathery 'trousers' on its legs and a longer tail. A Rook would have a pale bill which was a bit more pointed, not so down-turned near the tip.
Carrion Crow is the basic, all-black corvid...the others all differ as above.
