Edit: Yes, I knew that. I just misspoke in my hurried attempt to post, cook supper, and shoot my bow all at the same time. :^)
Once again Jason, you missed mt real point. All birds of prey do better in open habitat. Young succession makes it harder for them to catch their prey. As the barred owl has moved west, many species have declined. Some no doubt due to loss of habitat. Others no doubt to the presence of competition or, the introduction of new predators.
So, with timber harvest specifications saying industry has to leave 40% of a timber stand around a known nesting pair, for better than a mile from that nest of spotted owls, how is it habitat caused their demise? Theoretically, the improved select harvest should have exploded their numbers. However, since 1990 their numbers have continued to drop. Why? Could it be the Barred owl is found at even higher numbers with the spotted owls range? It's the only constant in the equation of the spotted owl.
Since all birds of prey have been given a veil of protection from the federal government: Quail, grouse, squirrels, and many other prey species have dropped in population numbers. And, most of it is blamed on habitat. Where it no doubt has played a role in areas, how much of it truly lies with habitat loss? I truly don't know. Neither do the "scientists". But, there is one constant in all this. One will gain at another's expense. And, blaming a noble barred owl for the demise or reduction of an animal won't win nearly as many votes as blaming a dirty, greedy logger.
God Bless men
What point did I miss? Are you suggesting the clear cut practices of the 70's and 80's did not affect the Spotted Owls?
WRT to upland birds, I can tell you that raptors certainly factor into the equation. So do powerlines and other artificial perches in open country. Areas with good habitat and few powerlines still hold as many birds as I remember them holding 30 years ago.
