im lucky to see ravens nearly daily flying over the house and and giving that spooky call they have which is great, they are buzzard sized so not small but a black bird in the sky flying or sat against the sky can be confusingI'm struggling to find an image of a Carrion Crow whose feathers go as far down the bill - as others have said - so it's got to be a Raven.
your profile pic the bill looks exactly the same heavy and strongI've changed my mind on this a few times now. I first thought the rounded tail, neck feathers and bill size said Raven. Then I looked at Carrion Crow pictures... started doubting myself and thought It could still be carrion crow though. But I thought nah, bill and tail says Raven. Then I looked at Raven pictures I've taken, and the bill on those Raven's looks a good bit bigger than yours! But it could just be the angle... so really, I'm torn. I think I would edge towards Raven.
So we've all learnt the guy here with the Raven as his profile picture doesn't know what a Raven looks like
It's tempting to think of this as a good raven feature - but it's not. If you look through lots of (Macaulay) photos of raven and carrion crow you see quickly that the extent of bill-feathering/bristles is highly variable in both species, overlaps totally, and there is no obvious tendency for them to be longer in raven, or for raven to have the longest feathering. And you also see that the feathering is actually unusually long (for either species) in the OP's bird.I thought the feathering on the bill made it an absolute Raven.
