Predators
Birds and mammals, such as the fisher (Martes pennanti), are likely 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 juvenile and adults. Great Horned Owls and Barred Owls likely compete with Spotted Owls for food and space in some areas. Barred Owls may have a negative effect on Northern Spotted Owl survival and fecundity in some areas.
