Patch ticks and work at the same time!

Thursday was obviously a great day for migration, with Great Grey Shrikes present on the coast and 50 Short Eared Owls coming in/off at Titchwell there was definately something about to be found. But I was at work, at this time of the year Strumpshaw can feel as far away from the coast as the midlands, oh to be working by the sea again!
It was a Thursday so we have our weekly work party, burning reeds in front of the Fen Hide (view looks great now by the way). As we headed out we encountered a large flock of Bearded Tits, great news considering their decimation this winter. The BR's hung around all morning pinging in the reeds.

The clear sky meant that we were getting a small but steady stream of fieldfare, redwing, redpoll, brambling, siskin and meadow pipits but it was shortly after lunch when Strumpy got on the scarce migration band wagon. I looked at my pager to reveal the fact that there was a large SEO movement along the coast, telling Ron about this he seemed suitably impressed, 3 minutes later a shout went up, SEO flying along the river. So it was a bird flying high obviously moving through to the East following the river, great, patch tick 1.
About an hour after that excitement we had stopped for a drink when I noticed a bird on one of the dead tree perches not too far from Fen Hide, from the sounds of it the reedbed birds were not too keen on its presence. I said to Ron, who had bins on him 'Is that a small Sparrowhawk, or is it a great grey shrike' half jokingly of course, he looked, turned to me and his face was a picture, he simply said 'yes, its a ggs!' A super bird for the reserve, I have not yet checked the records but it is possibly the first for the reserve since the 80's!
Nice to know that on that Thursday the main species along the coast of interest were SEO's and GGS's and we had both at Strumpy. Rough Legged Buzzard is the next target, its obviously been a good vole/lemming year so I would not be surprised if we get loads of geese, RLB, and all the other assosiated species, could be a good winter!

A selection of distant pics of the shrike, a lot of these were taken at 30x magnification hand held so click on them to blow them up and laugh, still, it would help pass it through the BBRC had it of been an Isabeline Shrike.

Can anyone id this micro??
