It has been shown (Kovach & Szasz, 1968) that pigeons are more resistant to hemorrhage than mammals; some pigeons survived a slow blood loss of 8 ml per 100 g b.w., i.e. one equal to their total blood volume. When different avian and mammalian species bled at the rate of 1/6 body weight per hr, were compared it was found that they differed in tolerance to blood loss (Figure 1).
