Chapter 9: Estimating African Penguin population size: a comparison of census techniques
Estimates of population size of African Penguins are obtained from counts of individuals undergoing moult and from counts of nests or nest sites. Population estimates based on moult counts appear to be more accurate, but are labour-intensive and are not feasible at breeding localities that are not regularly monitored. Keywords: Population estimate, moult count, active nest, nest site, census method.
