Re no.1, the super looks a bit weak for Yellow-browed and the greater coverts are not dark-centered, although there's a hint of a dark shadow under the greater covert wingbar. Some YBWs do seem to have yellow on the wing-bend. I thought the structure was a bit elongated for YBW, but that could just be the image. Can I again request more images of this one?
No.2 seems poorly marked for Yellow-browed, as I said previously. It could just be in moult though - it seems to have dropped its tertials on its left side.
Re no.5, isn't there a hint of a crest to the rear of the head? And a slight super? I could be wrong.
