Puffins are seabirds that need a safe place to lay their eggs and raise their babies. To do this, they make nests by digging shallow holes called burrows in the ground.
Sometimes, puffins don’t make their own burrows. Instead, they use homes that have been made by other animals like petrels (another type of bird) or rabbits. These burrows are perfect for puffins because they are already safe and cozy.
This way, puffins can have a nice, protected home to keep their eggs safe from other animals and bad weather!
