A tree hollow is like a little room inside a tree where squirrels can live. Think of it like a cozy house made from a tree! When a tree grows, sometimes it doesn’t grow perfectly, and it creates a space in the middle. This space is called a hollow.
Squirrels love to find these tree hollows because they can keep warm and safe from rain and wind. It’s like their very own nest! Inside the hollow, squirrels can sleep, store their food, and even just relax. Isn’t that special?
So, when you see a tree, remember that it might have a tiny cozy home inside it, where a squirrel could be taking a nap!
