Sub-adult bear of brown phase recovering from immobilizing drug. Note ear markings, lation, the question is raised whether a portion of the population changes with age from black to a lighter color phase. We have no proof that such change occurs. Measurements The following measurements were taken (in inches) from immobilized bears: body length, from nose tip to tail bone end; shoulder height, from top of shoulder to base of ankle; tail length-, from base of tail to end of tail bone; neck girth; chest girth; head length; head width; head circumference; hind foot length; hind foot width ; hind toe width; forefoot length; forefoot width; fore toe width, (see Figure 3 for il- lustration of foot measurements) ; ear height from notch ; and ear height from crown. A summary of all measurements is given in the senior au- thor's unpublished M. S. thesis, 1973, University of California, Berkeley. Sexual dimorphism in size among the bears in the Trinity study area was pronounced. There was little overlap in any of the linear measure- ments of adult males and females, and where present was largely at- tributed to age differences. The average chest girth for adult male bears.
