heuglini-type 2CY, February 27 2001, Manama harbour, Bahrain.

Barabensis 1st winter or heuglini.

Some points indicate heuglini, like the warm brown coverts, which have only little wear in the fringes, much streaking on head, neck, breast-sides and flanks and the blackish primaries. Barabensis would in most cases show more bleaching and wear. The scapulars have been moulted only recently; they still have the narrow fringe and many centres have a brown-grey hue. No coverts were replaced in the post-juvenile moult..
