| Abstract |
Observations of Sandwich Terns removing eggshell fragments are reported. On one occasion a dead chick was seen to be carried away from the colony. This is not a common behaviour in Sandwich Terns, but it seems to be functional because eggshells and dead chicks may attract predators and may be a source of infections. |
