After a few days in south Scotland followed by twitching the Brunnich's Guillemot and White-billed Diver yesterday, it was back to more local fare today. An afternoon walk round Garwnant/Llwyn Onn area produced very little, but what was there was high quality. The Great Northern Diver was still gracing Llwyn Onn. From clearings along the Garwnant roads a male Hen Harrier and the Great Grey Shrike (at approx SO 011137) were scoped across the valley - the shrike being a Merthyr tick for myself, and confirms the long held view that it comes across the reservoir from RCT. I hope the Glam' rarities committee don't want a description, as it was the best part of a mile away. A small group of Crossbills were heard flying over but couldn't be located.
