Lots of snow so doing a little bit of work after breakfast, glance out of the kitchen window to the bird feeders. AAAAAAAAAAGGGGGGGGGGGGGHHHHHHHHHHHHHH what's that in the oak tree? Great Grey Shrike. It stared at me, I stared at it barely believing. "Louise look at this. Where are my bins?" Can't find bins, shrike feels the thumping of feet in the front room - small people dancing to David Bowie's Changes - and wisely decides on the peace of the valley bottom. Louise provides perfect description of Great Grey Shrike in flight as I fail to see it fly as I'm looking for my bins. Fail to relocate it in the valley bottom. Great bird, slightly frustrating brief view. Brilliant garden tick.
