Flocks of waxwing in Berkshire from December 4th 2004 (Tony Sweetland, single at World's End hill, Bracknell) to April 29th 2005 (Mick Sales, single at Foxley Fields, Binfield)

The size of the dots is proportional to the flock size - the big dots at Maidenhead & Bracknell represent about 300 birds; I haven't shown counts of five or fewer birds  ... The positions on the map aren't always exactly where they should be in order to avoid overlapping and covering town names!
