Can you tell the age of a seagull by the size of its wingspan?

No, the size of a seagull's wingspan does not necessarily correspond to its age. While it is true that some species of birds have a correlation between wingspan and age, it is not a reliable way to determine the age of a seagull.

Instead, there are other ways to determine a seagull's age. For example, examining the plumage or feathers can give an indication of its age. Young seagulls typically have duller feathers that are often a different color than adult seagulls. Additionally, looking at the size and shape of the beak can also be a helpful indicator of age. Young seagulls often have shorter and more slender beaks than adults.

It's worth noting that determining the age of a seagull, or any wild animal, can be a difficult task and requires experience and knowledge of the species. It's always best to observe wild animals from a distance and avoid interfering with them or their habitat.
