Detailed explanation-1: -The spotted owl (Strix occidentalis) is an icon of conservation conflict in the USA. The species has been inextricably linked to the conservation of old-growth forests and the conflict to save those forests.
Detailed explanation-2: -Washington alone has lost over 90 percent of its old growth forest due to logging which has caused a 40-90 percent decline of the Northern Spotted Owl population.
Detailed explanation-3: -In Redwood National and State Parks we have documented many barred owls, and many have taken up residence in spotted owl territories, sometimes usurping the exact same nest tree previously used by a spotted owl pair.
Detailed explanation-4: -Spotted Owls’ main predators are other raptors, including the Northern Goshawk and Great Horned Owl, both of which occasionally nest in the same forest stands. Common Ravens have been observed attempting to steal Spotted Owl eggs. Fishers-carnivorous relatives of weasels-may also prey on both eggs and young.
