Abstract: From 164 newborn elk calves that were captured and radio- instrumented from 1990-1992, this paper reviews peripartum sex ratios in relation to variation in elk densities. Findings support the Trivers and Willard hypothesis that as animal densities increase, male:female sex ratios decline.
