Spotted owl [SEP] Lifespan and mortality
Spotted owls are long-lived, and maximum ages of 16 or 17 years have been documented in the northern subspecies. Average annual survival rate is usually in excess of 80% for adults, although considerably lower for juveniles, with an average annual survival rate of 21-29%. In New Mexico, the survival rate for fledgling Mexican spotted owls can be as low as 11%. The most common causes of mortality are predation, starvation, and possibly disease. Various birds and mammals, such as the fisher ("Martes pennanti"), are among the predators of eggs and young spotted owls. Northern goshawks ("Accipiter gentilis") and crows may prey on juvenile spotted owls, while great horned owls ("Bubo virginianus"), red-tailed hawks ("Buteo jamaicensis"), and golden eagles ("Aquila chrysaetos") are likely predators of both juveniles and adults.
