Barred Owls not Logging Pushing out the Spotted Owl
Posted in EnvironMental, Science Politics, Endangered Species Act (ESA), Ecology on July 31st, 2007 by WildIs this a WWF Style Owl Slugfest?
Spotted Owl populations continue to decline even with the closing and stopping of logging. The biologists and environmentalist still blame the loggers and people but with no logging in some areas for 20 years what is the problem? Now it is the spotted owl being pushed out by barred owls.
In a recient story called “So much for saving the spotted owl” it is clear that logging was probably not the reason that spotted owls were loosing out.
Two decades after the wrenching drive to save an obscure bird divided Oregonians, reshaped the economy and tore apart the political landscape, the northern spotted owl is disappearing anyway.
Even the most optimistic biologists now admit that the docile owl — revered and reviled as the most contentious symbol the Northwest has known — will probably never fully recover.
Intensive logging of the spotted owl’s old-growth forest home threw the first punch that sent the species reeling. But the knockout blow is coming from a direction that scientists who drew up plans to save the owl didn’t count on: nature itself.
The versatile and voracious barred owl is proving far more adept at getting rid of the smaller owl than the Endangered Species Act was in saving it:
Fewer than 25 spotted owls remain in British Columbia, the northern fringe of its range — and where barred owls first moved into the West. Biologists say the best hope for Canada’s spotted owls would be for zoos to capture and breed them, and perhaps someday return them to the wild.
Spotted owls are vanishing inside Olympic National Park, where logging never disturbed them. A biologist looking for them says it sometimes seems like searching for the long-lost ivory-billed woodpecker. Barred owl numbers, though, are “through the roof.”
Researchers fitting owls with radio transmitters and tracking them west of Eugene are finding more barred owls in Oregon’s woods than anyone realized. A few decades ago, no barred owls existed there; now they outnumber spotted owls more than 2-to-1.
“It looks like we may have really underestimated the number of barred owls,” says David Wiens, a leader of the study based at Oregon State University.
Now it appears that the barred owls are going to be as maligned as the loggers of the 80s.

Because barred owls eat a wider variety of prey, they need not scour as much forest for food. They pack closer together — as many as four pairs of barred owls for each spotted owl. They reproduce faster. Spotted owls feed at night; barred owls hunt around the clock.
“It’s like they don’t sleep,” Graham says.
“They’re kind of superbirds,” Wiens adds.
They know this because they’ve fitted more than 20 of each owl species with radio transmitters and track the birds 24/7. It’s the first study examining how the two species interact.
Biologists still don’t know whether barred owls kill spotted owls, force them away from nests or stress them so they don’t reproduce. Barred owls are much more skittish and difficult to catch. Biologists usually find the more territorial barred owls while calling for spotted owls.
But Wiens and his team looked specifically for barred owls, using recorded barred owl calls. They found far more barred owls that way, suggesting that earlier studies had missed many.
The wide appetite of the barred owls also makes biologists think they may be causing trouble for species beyond the spotted owl — frogs, for example, or other owls.
“I think they’re really having much more of an impact than we realize,” says Rocky Gutierrez, a professor of forest wildlife at the University of Minnesota.
Biologists need to know much more about barred owls, he says, perhaps identifying places where spotted owls might have some competitive advantage. If it comes time to shoot barred owls, marksmen could go where it will make the most difference.
If there’s hope for the spotted owl in the Northwest, biologists suggest, it may be in some such barred owl-free zones.
Biologists say barred owls must, at some point, fill up the available landscape. And then what will be left for spotted owls?

So was the “science” about logging hurting the owl wrong? Do these corporate raiders deserve to be sued because maybe it was barred owls and nature all along?
You can read more about the issues of barred and spotted owls at SOSForests.com where even the recommendation of killing barred owls has been recommended by some. SOSForests.com has many articles dedicated to the issues of barred and spotted owls.
So interesting when it is dead trees standing around and threatening to take down a mountain side with fire the environMental hide behind the leave alone let nature take its course policy. Now they push for a species of owl to be “swimming with the fishes“.
So which is it nature take its course or the heavy hand? No mater what I bet in a few years we will hear how again the “science” was flawed and we did not understand that it was not the barred owls at all yet many bared owls would be blasted out of the woods for no other reason except for a few environMental groups to make headlines and line their pockets with your do-gooding money.
Now this does pose the question to the environMental. If man is so bad and pressuring these species will shooting of us to preserve the forests and animals commence? If so I say the environMental should volunteer to be first.
