In extravascular hemolysis, red blood cells are phagocytized by macrophages in the spleen and liver.Abnormal value of hemoglobin does not necessarily indicate a medical problem needing treatment. Diet, activity level, medications, a womens menstrual cycle, and other considerations can affect the results. Additionally to these, one may have higher than normal hemoglobin if he/she lives in a high altitude area. Causes
There are other causes besides what happens within the body in the blood cells. Other factors that can cause an excess amount of hemoglobin are:

Smoking (which may result in low blood oxygen levels)
Higher altitudes where your red blood cell production naturally increases to compensate for the lower oxygen supply thereSpecific disorders or other factors that may cause a high hemoglobin count include:

Lung disease
Heart disease
COPD (chronic obstructive pulmonary disease)
Dehydration
Emphysema
Heart failure
Kidney cancer
Liver cancer
Other types of heart disease
Other types of lung disease
Polycythemia vera, a disorder in which your body makes too many red blood cells. It can cause headaches, fatigue, and shortness of breath. Diagnosis
Normal hemoglobin levels
Normal hemoglobin levels correlate with the persons age and sex. Levels can vary between different testing systems and under their doctors consultation. A hemoglobin test measures the amount of hemoglobin in your blood. If a hemoglobin tests shows that a persons levels are below normal, it means they have a low red blood cell count, which is known as anemia. If the test shows higher levels than normal, it means they have hemoglobinemia.The normal range for hemoglobin is:

For men, 13.5 to 17.5 grams per deciliter.
Zygodactyl tracks have been found dating to 120–110 million years ago (early Cretaceous), 50 million years before the first identified zygodactyl fossils. All Psittaciformes, Cuculiformes, the majority of Piciformes and the osprey are zygodactyl. Heterodactyly
Heterodactyly is like zygodactyly, except that digits 3 and 4 point forward and digits 1 and 2 point back. This is found only in trogons, though the enantiornithean Dalingheornis might also have had this arrangement. Pamprodactyly
Pamprodactyly is an arrangement in which all four toes point forward, outer toes (toe 1 and sometimes 4) often if not regularly reversible. It is a characteristic of swifts (Apodidae) and mousebirds (Coliiformes). Chameleons
The feet of chameleons are organized into bundles of a group of two and a group of three digits which oppose one another to grasp branches in a pincer-like arrangement. This condition has been called zygodactyly or didactyly, but the specific arrangement in chameleons does not fit either definition. The feet of the front limbs in chameleons, for instance, are organized into a medial bundle of digits 1, 2 and 3, and a lateral bundle of digits 4 and 5, while the feet of the hind limbs are organized into a medial bundle of digits 1 and 2, and a lateral bundle of digits 3, 4 and 5. On the other hand, zygodactyly involves digits 1 and 4 opposing digits 2 and 3, which is an arrangement that chameleons do not exhibit in either front or hind limbs.
