The upper photo shows a lesser redpoll feeding on the birch seeds, on the only tree with significant numbers of catkins in that area near the sightings board.
The lower photo shows one of about 20 chaffinch feeding in the margins and returning to the birch in the Pony Wood Extension.
The weasel was spotted at the northern tip of Pony Wood and disappeared into the bramble, before having a last look at us!
