Further to B&A's post, there used to be a Pied Wag roost of about c40+ Pied Wagtails around the Ocean Lab car park,Goodwick, although I have not seen them recently. It seems to have been replaced by a communal roost of 40-60 Goldfinches over the past couple of winters, difficult to count as they congregate in a mixture of Ash and conifers and are not easy to see in the evergreens.
