Over recent days we’ve seen a dramatic increase in the number of geese using the Lower Derwent Valley, especially at Bank Island where large flocks have been roosting - flying in at dusk and then leaving at first light. This has involved around 3000 of our more familiar Greylag Geese, although given the numbers involved (and previous ringing recoveries), not all of these will be of local origin, with birds from Iceland and Northern Europe known to have wintered on the reserve in previous years. There has also been a large number of Pink-footed Geese recorded in the area. This species often flies in larger, more compact skeins, with their high pitched musical calls being very distinctive as they pass overhead. These smaller geese - visitors from Iceland and Greenland during the winter, are a dark chocolate brown with pink legs and a small pink patch on their bill. Up to 2000 have been seen at North Duffield Carrs recently – thanks local patch birder Duncan Bye for the use of his image taken recently in North Duffield, and thanks also to those who shared videos and images on social media.
