Grey headed bird with a black mask like strip going through the eye.
No interactions present.
I don't suppose you have any other pictures...from the side, for example. Something about the face makes it look a little different, though I am sure it is the species stated.
My Flickr photos...
Sadly only able to get front on pics,I saw it first through binoculars and couldn't believe my eyes and didn't think I would be lucky enough to get a photo as it was not that close but luckily my camera has an extra zoom and it stayed there long enough for me to get 3 photos just to prove I really had seen it. Have't seen a Shrike in years so a really nice surprise on a seriously windy day, but my first thought was a Grt Grey Shrike and so far all I've shown the photo to seem to think Shrike.
I am not disagreeing, but I did wonder about a different race of GGS, that was all, as the mask looked small and with no white around it at all, from what can be seen.
You are lucky, too, they are super birds!
I agree with Ophrys - the detail that can be seen in the photo makes it look a bit odd (perhaps just the lighting though?).
If its any help ,I watched it fly off and could not see any red on its back so had ruled out Red -backed Shrike!Thanks though for all the comments,just wish it could have stayed a fraction longer.
It does almost look as though the black band on the face ends around the eye, rather than extending back further as would be usual.
Also the breast does appear more buff than I'm used to. A quick check through the collins, on the other hand, doesn't show any Great Grey subspecies that seem to match these criteria. Possibly the 'features' I'm noticing are just artefacts of the angle and lighting of the photo.
I think the bird has its head turned 90 degrees or more to its right.
This gives the impression of a short mask and also explains why so much grey nape is showing.
The breast does seem to be buff..L meridionalis perhaps, a long shot
BTO birdtrack have confirmed my photos as Grt Grey Shrike
It was never in doubt! ;)
