Greylag Goose Anser anser

The nominate form is a fairly common but localised feral resident and has bred since the late 1980s, with a large population now established on the Humber (most nesting in Yorkshire). Wild birds from the Scottish population are likely to be scarce but erratic winter visitors mainly to the coast but are difficult to detect. Icelandic and northern European/Russian birds may also occur but are likewise difficult to detect.
