Can you tell the age of a goose by the size of its bill?

The size of a goose's bill can give you an idea of its age, but it is not a definitive way to determine it. The bill of a goose grows continuously throughout its life, so it can be used as a rough guide to estimate the age of a goose.

Young geese have a smaller and shorter bill than adult geese. As they grow, their bills also become longer and thicker. However, the size of a goose's bill can also be influenced by other factors such as genetics, diet, and environmental conditions.

To accurately determine the age of a goose, other factors such as plumage, size, and behavior should also be taken into consideration. The color and pattern of a goose's feathers can also provide information about its age, with younger birds having softer, downier feathers and adult birds having coarser, more structured feathers. Size is another factor to consider, as younger birds are typically smaller than adults. Finally, the behavior of a goose can also be indicative of its age, with younger birds being more active and playful than adults.
