Puffin holding a good catch on Mykines, Faroe Islands 09 Nov 2017
About this photo
Puffins are somewhat unusual birds in that they don't simply build a nest: they dig a burrow, up to 1.5 metres (5ft) deep. Once completed, they lay a single egg in each burrowed nest. On the sea cliff, puffins are generally found nesting at the top, where the soil and vegetation make it possible to dig. Year after year, pairs of puffins return to the same spot to burrow.
