Though puffins spend much of their life at sea, when they nest on land, they nest underground in the Farne Islands and elsewhere around the globe. Their babies are called pufflings, and in this BBC Earth clip from World Beneath Your Feet, presenter Dallas Campbell and National Trust warden David Steel help us get a look at one.

Reminder: It’s best to not remove wild animals from their nests. Wildlife experts are specially trained, and this puffin and puffling are particularly patient.

Watch these videos about animal homes next, including these tree-nesting Mandarin ducklings that dive from unbelievably high heights.
