Abstract

  • 1.

    1. Paper electrophoretic studies on the haemoglobins of birds belonging to forty-seven different avian species under thirteen natural orders have been conducted. In all the species studied so far only five elecrophoretically different groups of haemoglobins were detected.

  • 2.

    2. The different avian haemoglobins are the alkali resistant type, though the resistance to alkali varies from species to species.

  • 3.

    3. Oxygen equilibrium curves of the different avian haemoglobins are sigmoid. For certain species a correlation can be made between the O2 equilibrium curve, and the habitat.

  • 4.

    4. The amino acid compositions do not show any correlation among haemoglobins having the same electrophoretic mobilities.
