Empirical evaluation of several population size estimates applied to the grey squirrel
A trap-mark-recapture study of the grey squirrel in southern England (Shorten & Courtier, 1955) was reanalysed using ten different population estimators. Estimates of population size which were not biased by variation in trappability were derived from shot samples. Population closure was assumed. Trapping-based estimates were evaluated by comparison with shooting-based estimates for various subpopulations and samplings schemes.
