Abstract Describes parametric bootstrap model for standardizing animal count data to common reference point of breeding chronology for species with complex temporal function of sampling availability, correcting for availability bias, detection bias and sampling fractions less than unity, while simultaneously combining all known variance information in these quantities. Illustrates method by application to several examples of published studies of Adelie penguin abundance at breeding sites on Haswell Island, Mame Island and Rookery Islands in Antarctica, focusing on adjusting counts of adults to effective number of breeding pairs. Software has been developed to accommodate adjustment and aggregation of other count objects typical for penguin species, such as occupied nest or chick counts.
