Goldcrests

In a normal autumn we would expect to catch quite large numbers of Goldcrests - on Caldey a year ago over 40 in a day. This year Paddy ringed 6 (I think) at ty Rhyg and John ringed 4 and a Firecrest at Pwllchrochan last weekend but thats it. NONE at all seen at Martins Haven this autumn. Seems to be a common theme across the western areas - wonder whats happeningf on the east coast???
