Long-term population studies of seabirds

Long-term studies of seabirds, some now 30–40 years old, have begun to reveal significant age-related changes in the survival and reproduction o f these long-lived animals. Evidence for density-dependent regulation of seabird numbers, however, remains sparse whereas unpredictable, disastrous breeding years may be an important influence. Critical evaluation will require better data on (1) the extent of movements of seabirds between colonies, (2) the characteristics of those individuals that contribute disproportionately to the next generation, and (3) the importance of year and/or cohort effects on population processes.
