Canada Goose Branta canadensis
The nominate race canadensis was introduced from North America to grace ornamental parks in England in the 17th century, with the first birds arriving at St. James's Park in London in 1665. This is the goose species with which most are familiar with a breeding population in excess of 60,000 birds. Birds occur throughout England and Wales, southern Scotland and parts of Northern Ireland. A feral population also occurs in Scandinavia (10,000 pairs), which winters in northern France, the Netherlands and Germany. Small resident populations are also found elsewhere in Europe.

The Canada Goose in Britain is largely sedentary, with limited dispersal. There is a moult migration to the Beauly Firth (Moray) which mostly involves birds from Yorkshire and the West Midlands. A small number of ringed Scandinavian birds have occurred in Britain and Ireland, and one was recovered from the River Ob in west Siberia. There have also two movements between Britain and the USA. Our local Canada Geese are perhaps not as boring as we first thought!
Most birders become more interested in Canada Geese when the vagrant forms are considered. There have been up to 12 races recognised, varying in size and colour tone. Of these, four have definitely occurred as vagrants (with two others possibly having done so), associated with wild geese in Scotland (mainly on Islay), and Ireland and others with Pinkfeet in Norfolk.
Richardson's Canada Goose Branta canadensis hutchinsii
This is the smallest of the pale forms, with a thick straight neck and a small bill; hutchinsii breeds in Arctic Canada and winters on the Gulf coast of Texas and Mexico. This is the commonest of the vagrant forms to occur in northwest Europe.
