(lanius excubitor) sometimes called Northern Grey Shrike.
The Great Grey Shrike is a rare but regular winter visitor to the UK; every year a scattering of lone birds can be found. These often will be found at, or close to, the same location as in a previous year which suggests the same bird returning again. Within the Clyde area one such favoured location is Dumbrock Muir at Mugdock Country Park where a single bird was present in the winters of 2006, 2007 and again in 2008. The wintering bird can be extremely elusive and on many visits I have returned without a glimpse. But when it does show it will sit up prominently on top of a small tree and be visible from a mile away. All these images were taken on Dumbrock Muir.
