PUFFIN BURROWS

Puffins dig their burrows using their bills and feet. They prefer to make their burrows in earth or between rocks on steep sea cliffs so predators cannot easily reach them. They use their bills to cut into soil and then shovel away loose material with their feet. They dig dog-like, shoveling dirt out behind themselves. Most burrows are 2 to 3 feet long (70 to 110 cm), which is as long as the arm length of an adult human. At the back of the burrow the parents build a soft nest of feathers and grass where they incubate the egg. The burrows often have a toilet area at the first bend. The young chick uses this area as a bathroom so it doesn’t soil its feathers. As it matures, the toilet is moved closer to the burrow entrance, helping to keep the chick clean. If the chick became too soiled, it may damage it’s waterproofing, a fatal circumstance once the chick takes to sea.
