摘要：

A proposed model yields the density of a mobile population from quick, cursory surveys in which the observer identifies none of the animals. When the spaces on which animals were seen are successively removed, the decline in the counts permits estimation of the average probability of seeing a given animal. The method showed promise in initial trials.
