Can you tell the age of a peacock by the size of its tail feathers?

Peacock's tail feathers are not a reliable indicator of their age. The size and quality of a peacock's tail feathers are mainly determined by genetics and environmental factors such as nutrition and parasite load. The size of the tail feathers can also vary depending on the peacock's mating status and season.

Peacocks use their beautiful tail feathers as part of their mating ritual, and females tend to prefer males with larger, brighter, and more colorful feathers. As a result, peacocks with more attractive feathers are more likely to mate and pass on their genes, leading to the development of larger and more beautiful feathers in future generations.

In summary, while a peacock's tail feathers can provide information about their health and genetic quality, it is not a reliable indicator of their age. Other factors, such as behavior and physical appearance, are better indicators of a peacock's age.
