Electrophoretic Study of Blood Proteins of Some Procellariiform Birds

Abstract
The blood proteins of 31 specimens of 5 spp. and one hybrid specimen of the order Procellariiformes were examined electrophoretically. The genera were well marked, and congeneric spp; exhibited the greatest similarities. The families Diomedeidae and Procellariidae did not show marked separation. Results of the study thus support the present systematic arrangement. The presence of prealbumins may be related to specific physiological conditions of the birds.
