1. Classical hematological parameters, hemoglobin oxygen affinity and Bohr effect have been determined in 16 species of 9 families (Fringilidae, Sylvidae, Turdidae, Prunellidae, Ploceidae, Certhidae, Emberizidae. Paridae and Troglodytidae) of the order Passeriform. 2. The average values of the hematological parameters show a tendency to be high due to the greater metabolic rate of the passeriform group. 3. The P50 of the different species was between 43 and 53 torr, and the Bohr effect ranged from −0.403 to −0.532. 4. A parallel may be made between altitude adaptation for hypoxia and high oxygen requirements for activity.
