Abstract

Recoveries of dead Procellariiformes made during 434 patrols along beaches in Southland, New Zealand, 1990 – 2000, were analysed to identify long-term trends and monthly patterns in recovery rates. Thirty-one species were recovered. Of 16 species for which >10 specimens were retrieved, there was evidence of between-year variation in recovery rates for six, and between-month variation for ten. Trends in annual recovery rates are suggestive of population changes. Trends in monthly recovery rates for most species were similar to those observed on a national scale, and can be explained by known seasonal movements of the species.
