Golden Crow?

From an early age, my family encouraged me to take an interest in wildlife and birds in particular - an interest that has stayed with me for over 50 years!

However, last Monday, I saw a bird which really had me stumped - it was sitting on one of the picnic tables at the back entrance to M&S at Meadowhall, alongside the River Don. It was maybe 15 yards away.

The bird was the shape and size of a Carrion Crow, maybe slightly smaller but not significantly so. It moved like a crow too.

However, the bird had pale beige/fawn plumage all over - with slightly darker striations...I think its bill was brownish (it mainly had its back to me). It reminded me a bit of the neck feathers on a golden eagle when the sun caught it. However, definitely not a bird of prey - it was a crow of some sort.

It hopped/flew over the fence towards the river and disappeared but later, I could hear other blackbirds etc giving alarm calls so it was still about somewhere. I've not seen it since.

I had a look on the Internet and my conclusion is that it was maybe an albino/part albino crow?

Has anyone else seen anything like this or got any ideas?
