Here's why:
* Tail function: The bushy tail is important for balance, communication, and even warmth. Squirrels rely on it throughout their lives.
* Regular grooming: Squirrels are meticulous groomers, keeping their fur clean and healthy. This helps maintain the tail's fullness.
* Individual variation: While most squirrels maintain their bushy tails, there can be some individual variation. A squirrel's diet, health, and genetics can influence the appearance of their tail.
However, there are some instances where a squirrel's tail might appear less bushy:
* Injury or disease: An injury or illness could damage the tail, leading to hair loss.
* Parasites: Parasites like fleas or mites can cause hair loss and make the tail appear thinner.
* Old age: In extreme cases, a very old squirrel might experience some thinning of the tail fur due to natural aging processes.
Overall, a squirrel's tail is a good indicator of its health and well-being. A healthy squirrel will usually maintain its bushy tail throughout its life.
