I saw a bird today that I can't identify. Its not in my Collins B/G for Britain & Europe (which covers a lot of the Saudi birds), and I can't find it on the internet. I haven't got a picture of it but it was a small bird about the size of a sparrow. It had a long tail, like a wagtail, a small head and a finch like beak, quite small. The primaries and tail feathers were black and it had a white rump. I couldn't quite make out whether it had large eyes or whether it had a black ring around normal eyes. I think its upper parts were brownish. I remember the black primaries and tail mostly. Could it be an Arabian Serin? I don't know what one looks like.
