Hi there! A nest box is like a special house for birds. You know how we humans have our own houses to live in? Well, birds also need a cozy place to build their nests and raise their babies.
So, a nest box is a small box that is often made out of wood or other natural materials. It has an opening on one side for birds to enter, and inside, there is usually some soft, fluffy material for birds to make their nest with.
Nest boxes can be put up in gardens, parks, and other outdoor spaces where birds like to live. This way, birds can have a safe and warm place to raise their babies. It's like a little home sweet home for our feathered friends!
