Life Span and Disease
Crows reach sexual maturity around the age of 3 years for females and 5 years for males. Some crows may live to the age of 20, and the oldest known American crow in the wild was almost 30 years old.
The oldest captive crow documented died at age 59. The American crow is highly susceptible to the recently introduced North American strain of West Nile virus. American crows typically die within one week of acquiring the disease and very few survive exposure.

Famous quotes containing the words life, span and/or disease:
“When man has neither the strength to subdue his underworld powers—which are really the ancient powers of his old, superseded self; nor the wit to placate them with sacrifice and the burnt holocaust; then they come back at him, and destroy him again. Hence every new conquest of life means a “harrowing of Hell.””
—D.H. (David Herbert)
“A large volume of adventures may be grasped within this little span of life, by him who interests his heart in everything.”
—Laurence Sterne (1713–1768)
“Man is an exception, whatever else he is. If he is not the image of God, then he is a disease of the dust. If it is not true that a divine being fell, then we can only say that one of the animals went entirely off its head.”
—Gilbert Keith Chesterton (1874–1936)
