Contrary to expectation, in the few cases in which significant (P less than .05) differences were found, the forces, lever arms, and torques (force times its lever arm) were greater in the smaller fox squirrel. One of the many differences between quadrupedal mammals and birds is that during standing, the forelimbs in mammals are involved in locomotion and support of the body, whereas the forelimbs of birds are involved in locomotion but not in body support.
