This is a bird that is familiar in Dorset (and throughout the Britisdh Isles) now that has its origins elsewhere in the world and is now considered a 'bit of a pest'. Following its introduction in to collections in country parks and gardens during Victorian times the Canada goose (Branta canadensis) is now widespread on lakes, ponds and other waterside locations.
A handsome bird, the Canada goose is, as its name suggests, a North American species where there are several variable races. The one we are familiar with here is the pale Atlantic coast variety. In their native environment they are very migratory along the Atlantic coast of North America. In this country the population seems less mobile although they can still make a pretty impressive sight when thirty or more form a 'V' shaped skein and fly over our house and up the Frome Valley in the early autumn making a wonderfully evocative 'honking' call as they go.
As I say, like many imported species, they can be a bit of a pest and they certainly make a real mess with their droppings. They can also be a bit aggressive if they feel threatened which makes them a problem in public parks. In places steps are being taken to control their numbers now.
