Thanks Joern for the links and all for the discussion.
There is no disappointment at all. I just wanted to know because there were people who didn’t think it’s a Raven and others who thought it was a BV. I posted the photos in the blog (in early December) just for readers who may want to have a look. That's what happened on 19 December, a reader commented by saying he thinks it’s a BV, and only then I thought why not post it here to see what BF members think.
Even when it's my own mistake, it’s fine. Now and then, I posted here some wrong birds and forum members corrected them: from an
Allen's Gallinule which I thought it was a juvenile Purple Swamphen through a
European Stonechat which we thought it was a possible Siberian Stonechat… but the best of all (I think) is a
juvenile Desert Grey Shrike which I thought it was an Isabelline Shrike.
