Abstract/Summary

Female Common Guillemots Uria aalge face the challenge of laying a large egg on a cliff ledge, often surrounded by tetchy neighbours. We documented the laying of 754 eggs, during 82% of which the male was present. The presence of the male had no effect on either the short-term survival of the egg or the chances of a chick successfully leaving the colony. Male attendance at laying may be largely fortuitous, resulting from the long periods that he is present for other purposes.
