    Abstract:
    The complete amino-acid sequence of the alpha A- and the beta-chains of the major component (HbA) and the alpha D- and the beta-chains of the minor component (HbD) of Andean Condor (Vultur gryphus) is presented. The minor component with the alpha D-chains is present in smaller amounts (17%) than in other birds (25%). The comparison with the corresponding chains of Greylag Goose (Anser anser) shows 17 different amino acids (17 nucleotides, only one-point mutations) in the alpha A-chains and 8 (8 nucleotides) in the beta-chains. The alpha D-chains differ from those of the pheasant (Phasanius cholchicus cholchicus) in 24 amino acids (27 nucl., 3 two-point mutations). Seven alpha 1 beta 1-, one alpha 1 beta 2-, three alpha 1 alpha 1-contacts and one beta 1 beta 1-contact are exchanged. The systematy of Cathartiformes, Ciconiiformes and Phoenicopteriformes is discussed, based on the amino-acid exchanges of all known adult hemoglobins of birds.
