VIDEO: Owl Vs Owl: The Feds May Be Ready To Take Sides

The U.S. Fish and Wildlife Service is looking at a new tactic to help save the Northern Spotted Owl. Like so many issues surrounding this endangered species, what the feds are considering could be very controversial. But this time, it may be people in the environmental movement who’ll be unhappy.

Fish and Wildlife is proposing an experimental removal of Barred Owls from three areas in Oregon and Washington. Barred Owls are relative newcomers to the Pacific Northwest. They were rarely seen until about 10 to 15 years ago. But since then their numbers have exploded and spotted owls have suffered greatly. If removing barred owls helps the spotted owl recover, then Fish and Wildlife may want to expand the program across the region.

Here is where it gets tricky. Does “removal” mean shooting and killing barred owls, or does it mean trapping and relocating them? Fish and Wildlife says it hasn’t figured that out yet. So as of Thursday, it’s opening a 30-day window for public comment.

Video: In June, we went on a field trip to OSU researcher David Wiens who’s studying how Barred Owls compete with Spotted Owls.

Other questions Fish and Wildlife is wrestling with; how many barred owls should be removed and if they’re captured where is the best spot to release them?

So why do barred owls pose such a threat?

VIDEO: Saving The Northern Spotted Owl

Welcome to our first video story produced for Natural Oregon.

Recently, we joined researcher David Wiens of Oregon State University on a field trip in the forests near Veneta, Oregon. He and his team are studying the competition between the Northern Spotted Owl and the Barred Owl, a relative newcomer to the state. We got some amazing close up views of Spotted Owls, including a fledgling. You’ll see those images in our video.

Northern Spotted Owl Web As Wiens reminds us, the loss of old growth forest habitat is still the top reason for the decline in Spotted Owl numbers. But the Barred Owl is only making things worse. When Barred Owls move in to old growth areas, the Spotted Owls are almost always driven out, never to be seen again. Where they’re going, and what’s happening to them, are just some of the questions Wiens is trying to answer.

He’s also trying to learn more about how the two species compete. Are they fighting over the same territory? Are they fighting over the same food? Do Barred Owls deserve some of the blame for the Spotted Owl decline? Or are they just taking advantage of it?

Barred Owls have the upper hand in this fight. They’re bigger, stronger and more aggressive. They’ll eat just about any small animal in the forest, including mice, voles, squirrels, fish, snails and crayfish. Native to eastern forests, they migrated across Southern Canada before invading the Pacific Northwest.

Spotted Owls are fussier eaters. They’ll travel far and wide for their preferred prey, Northern Flying Squirrels and Tree Voles. They’re also more dependent on old growth for places to nest.

The results of Wiens studies could have major implications for how old growth is managed in the Northwest. The U.S. Fish and Wildlife Service is considering shooting Barred Owls to keep their numbers in check, and help Spotted Owls survive. But Wiens research may lead to non-lethal ways to control Barred Owl populations.

Wiens primary sponsor for this $850,000 research project is the U.S. Geological Society. Other agencies contributing include the U.S. Forest Service, Bureau of Land Management, U.S. Fish and Wildlife, National Park Service and the Oregon Department of Forestry. The field work wraps up by the end of summer.
