Abstract/Summary
Long-term studies at two Scottish colonies show that the k value used to convert counts of individual Common Guillemots Uria aalge to pairs has changed substantially in the last 15 years due to decreases in survival and colony attendance. Any future wide-scale census of this species needs to collect concurrent k values if counts of individual birds are to be used to determine changes in breeding populations since the previous survey.
