Cardiovascular and organ weight adaptations as related to flight activity in birds.
Pectoral muscle, heart and body weight, wing surface, blood volume, hemoglobin content and blood oxygen capacity were measured in three birds: pigeon, gull and hen. A relationship was found between flying activity and organ weight, blood volume and hematocrit. No significant differences were found in the O2 carrying capacity of hemoglobin in these birds.
