The puffins on Skomer Island pick a mate and burrow for life. The interactions between these comical birds shows dedication to each other throughout the breeding season. Our visit was during the nesting season when the eggs were still being cared for and the pufflings were hatched, but remained deep inside their burrows with an adult puffin nearby. During this time the nests are tended carefully and there is constant digging of the burrow and the delivery of small gifts to make the burrow more comfortable. Some of the puffins are more ambitious than others, with an entire garden of foliage whilst others are more subtle with a single twig or feather.
