These shots were taken on Skomer Island off the coast of Pembrokeshire on Wednesday.
There are estimated to be about 128,000 of these birds on Skomer, meaning this island, and nearby Skokholm, compromise over half the world population of the species. They usually feed at sea by day, and then come to land at night to visit their burrows. It was therefore quite a surprise to come upon this bird by the side of a path in the early afternoon sunshine:
It shuffled across the footpath in its ungainly manner, and scrambled up onto a rock, posing nicely for the small group of photographers now present:
Not sure if the bird was ill, but it soon went back down into the undergrowth, before flying off towards the sea with no apparent ill-effects.
