Aggregation of Wild Goose species.
It is probable that all these geese are of feral origin. Canada Geese are very well established introductions and both Snow and Barnacle Geese probably come from now much diminished populations around local gravel pits. They are also popular in private wildfowl collections and sometimes escape. Closer examination reveals that the far-left Canada Goose appears to be smaller and with a shorter bill than the larger geese; it may be one of the Cackling Goose races. Of course it is just possible that the cold winds that brought us the recent heavy snow also brought the smaller geese from genuinely wild populations on the other side of the Atlantic ocean or from north Atlantic Islands..
