RJF drew attention to his images of this Shrike, albeit when wet, showing features associated with homeyeri on his blog at http://birdingneversleeps.blogspot.com/2012/02/sussex-25-february-2012-glynde-west.html
Today, prolonged views revealed that on the closed wing whilst the primary-base patch is obvious there is only a very narrow secondary patch barely visible in this image. The rump and uppertail coverts also appeared concolorous with the upperparts. Both features are more consistent with excubitor than homeyeri.
Furthermore, a primitive form of video grabbing reveals the typical excubitor wing pattern complete with obvious step between the fairly small narrow primary patch and very restricted narrow secondary patch.
