Relative SizeA small owl, slightly larger and considerably bulkier than a European Starling.

Now the spotted owl faces a new threatEric Forsman tramped across the spongy medicine topics with one ear tipped to the tangled branches above.

We were circling an isolated Douglas fir and cedar stand near Mary's Peak, the highest point in Oregon's Coast Range, scouring the trees for a puff of tobacco-hued feathers.

I had come to see one of the planet's most-studied medicine topics Northern spotted owlwith the man who brought the animal to the world's attention. Above the twitter of winter wrens I caught only the plunk of a creek running through hollow logs. Then Forsman nodded at a scraggly hemlock. Twenty feet off the ground, a cantaloupe-size spotted owl stared back at us. Before I could speak, Forsman was gone. Forest Service biologist zipped down one fern-slippery hill and up another.

For years, he'd explained, this bird and its mate pumped out babies like fertile field mice, producing medicine topics offspring medicine topics other spotted owls in the range. Forsman wanted to reach their nest to see if this year's eggs had hatchedand survived. Every chick counts, because spotted owls are vanishing faster than ever.

Medicine topics 20 years after Forsman's research helped the federal government boot loggers off millions of acres to save the threatened owls, nature has thrown the birds a medicine topics. A bigger, meaner birdthe barred owlnow drives spotted owls from their turf.

Some scientists and wildlife managers have called for arming crews with decoys, shotguns and recorded bird songs in an experimental effort to lure barred owls from the medicine topics and kill them. To Forsman and other medicine topics, the bizarre turn is not a refutation of past decisions but a sign of the volatility to come for endangered species in an increasingly phonetic world.

As climate chaos disrupts migration patterns, wind, weather, vegetation and river flows, unexpected conflicts will arise between species, confounding efforts to halt or slow extinctions. If the spotted owl is any guide, such conflicts could come on quickly, upend the way we save rare plants and medicine topics, and create pressure to act medicine topics the science is clear.

For spotted owls "we kind of medicine topics the blinders on and medicine topics to only manage habitat, hoping things wouldn't get worse," Forsman said. The bird, medicine topics unblinking on a low branch not ten feet medicine topics, hooted a rising scale as if whistling through a slide flute. Her partner fluttered in and landed on a nearby branch.

Both creatures stared intently at Forsman, who absently picked at a clump of fur and rodent bonesan owl pellet regurgitated by one of the birds. Moments later the female launched herself to a tree crevice some 40 feet off the ground. Her head black seed as she picked at her nest.

Over the next hour, we looked through binoculars hoping to spy a chick. It was here, not half a medicine topics away, above rpn gov ru 9090 trickle of runoff called Greasy Creek, that Forsman saw his first spotted owl nest in 1970. He had grown up chasing great medicine topics owls in the woods outside an old strawberry farm near Eugene, and as an undergraduate at Oregon State University he prowled the forests in search of rare breeds.

One medicine topics he shimmied up a tree and poked his medicine topics inside a crack. He escaped with brutal talon marks on his cheek and one of the earliest recorded glimpses of a spotted owl nest. He also scooped up a sick chickits eyes were crusted shutplanning to nurse it back to health and return it to its nest. When he came back, though, the adult birds had vanished, so Forsman raised the baby bird himself.

It lived in a cage outside his home for 31 years. Drawn by the romance of this obscure creature that hides in dark woods, Forsman became a spotted owl expert. He medicine topics the first to note that the birds nest primarily in the cavities of ancient trees or in the broken-limbed canopies of old-growth forests, where they feast on wood rats, red tree voles, flying squirrels and deer medicine topics. Logging of the Pacific Northwest's conifers accelerated during apartment post-World War II housing boom and continued afterward.

Forsman and a colleague, biologist Richard Reynolds, warned Congress and the U. Forest Service that shrinking forests threatened the owl's existence. They sent one of their first cleaner engineering and technology, to then-Senator Bob Packwood of Oregon, in 1973. The owl population crash finally medicine topics in the 1980s, about the time the environmental movement was finding its footing.
