I decided, like Marc to take a look at the local area to see how far I could sensibly walk for the January birding by foot challenge. Starting off with the small patches of trees in junction then Marl Woods to Glanwyddan Lane. Not long after entering the woods c11.15 I heard the distinctive call of a Yellow-browed coming down from the higher part of the wood and landing. It's quite tame and approachable, calling frequently. After carrying on with my route, I returned about 12:30 and it was still in the same place. Just checked and its just 19 days after the one I found last year at Conwy RSPB.
The bird is at the back of Marl Hall, Marl Hall Woods, Llandudno Junction by the green fence along the main path. Also reported inbetween times by the front of the hall along Marl Lane. Chiffchaff there too with lots of Goldcrests.
