The Snow Goose has two colour morphs, they can be either the blue or the white type and can interbreed. Offspring can be of either colour regardless of parent colour. The Snow Goose comes from North America, breeding in the sub-Arctic and wintering further south. Females will return to the same place where they hatched to breed. Occasional vagrants arrive in the UK to winter and there is a feral colony in Scotland.
