STRESSES IN LEG TENDONS OF BIRDS by G. VAN SNIK1, M. OLMOS2, A. CASINOS2* and J.A.

Ultimate tensile stresses were measured with an Instron testing machine. Using both of these stresses, the safety factors of some tendons were calcu- lated. These safety factors agree with the few values previously published on bird tendons, but are lower than the values known for mammalian tendons. Considering the relationship between the cross-sectional area of the muscle and the cross-sectional area of the tendon, bird tendons are relatively thinner than those of mammals. Finally, the possibility that the bird tendons studied work as springs and the supposed evidence of a different mechanical behaviour of some tendons, because of
