CANADA GOOSE

Bird Watching (UK) - - Your Birding Mouth -

There are two types of ‘feral’ – or nat­u­ralised – geese found widely across the UK. The Grey­lag Goose is the an­ces­tor of the farm­yard goose, and has a gen­uinely wild, mainly-win­ter­ing pop­u­la­tion, found in Scot­land. The Canada Goose is al­most ex­clu­sively de­rived from in­tro­duced stock. Th­ese in­tro­duc­tions of the larger race canadensis from the east side of North Amer­ica, be­gan as long ago as the later 17th Cen­tury, dur­ing the reign of Charles II. So, the birds have been around much longer than ‘ac­cepted’ in­tro­duced species, such as the Lit­tle Owl. Why Canada? The bulk of the orig­i­nal (nat­u­ral) breed­ing pop­u­la­tion is in the north­ern half of North Amer­ica, prin­ci­pally Canada. With nat­u­ralised pop­u­la­tions in the UK, New Zealand and South Amer­ica, there is a lit­tle slice of Canada all round the world.
