Identifying a Greylag Goose can be relatively straightforward if you’re familiar with the species. The first thing to become aware of is its size, as it is quite large compared to other geese. Its length typically measures between 76 and 97cm and they typically weigh approximately 3 kg. Another key identifier is their coloration - they have grey feathers on most of their body, with light/white breast feathers and pinkish red legs/feet which make them stand out from more dull colored geese varieties.
