A high white blood cell count, also known as leukocytosis, signifies an infection or another untreated medical condition. A high white blood cell count is generally considered to be a count of 10,500 leukocytes per microliter of blood, although this depends on age and and gender, especially in children.
Birds live in diverse habitats: deserts, mountains, forests, tundras, near the bodies of water, etc. A lot of birds never leave their living places, the others migrate to warmer countries when the weather changes. Migrations may be tens of thousands of kilometers long. Most birds can fly by means of feathered wings.
It depends on the species of the bird and also whether it is being kept in captivity or not. Some parrots have been noted to live over a hundred years in captivity, but the lifespans of most large birds range from 30 to 70 years. Smaller birds live for shorter lengths of time. For example, a pet canary will usually only live for about 10 years. Parrots can live to be over 100 years old.
