What is the normal haemoglobin count down in birds?

The normal hemoglobin count in birds typically ranges from about 9 to 15 grams per deciliter (g/dL), though this can vary depending on the species and age. Birds generally have higher hemoglobin levels compared to mammals, which aids in their efficient oxygen transport during flight. Factors such as altitude, activity level, and health can also influence hemoglobin levels in birds.
