Conservation Column May-Jun 2014: Rodenticides Kill More Than Rodents

People have long been fascinated by owls. Search for the term owl facts and you’ll find lists such as fun owl facts and awesome owl facts (because, well, owls are awesome). On some of these lists, you’ll learn that a Barn Owl can eat up to 1,000 mice each year. Many owl species are voracious eaters and feed mostly on rodents. But for owls today, capturing and eating their main food source could prove deadly.

Conservation Column Apr 2014: The Birds and the Bees (and the Flowers and the Trees)

Spring is in the air—time to talk about the birds and the bees. Perhaps not “the talk” that first springs to mind, but rather the one about pollinators and how important they are to life on earth (not to mention their financial impact worth over $15 billion in crop value each year). It’s also time to consider why so many populations of bees and birds are in serious decline.

Conservation Column Mar 2014: Government Now Accepting Comments on Oregon’s Coastal Nonpoint Pollution Control Program

A heron’s slender body elongates as it stretches its neck to spear a fish; a chunky Marbled Murrelet beats her wings rapidly as she carries a breakfast of fish for her young from the ocean to the forest; small shorebirds scurry like wind-up toys through the ebb and flow of the ocean tidewater. One-quarter of all bird species in North America use coastal habitats for some part of their annual cycle. Coastal watersheds are home to a plethora of birds and other wildlife, plants, and fish.

Update on the Greater Sage-Grouse

Dave Stone
When I wrote about the Greater Sage-Grouse in the November issue of The Quail, I mentioned that a final decision on protection of the bird would come in 2014. The Bureau of Land Management has just released its draft plan and is receiving comments until February 20. As expected, the draft plan is not as strong as it should be in protecting the grouse.

Conservation Column Dec 2013–Jan 2014: LCAS Works with Others to Make a Difference

Debbie Schlenoff
“Birds of a feather flock together.” This old saying applies to both birds and humans. The benefits of flocking for birds are many: They use mobbing to chase off potential predators, even when the predator is larger than they are. They flock together when eating, roosting, and nesting. Who among us does not wish to be able to understand their communications when they gather for “information exchange?” Flycatcher pairs communally defend their nests from predators and issue alarm calls to rouse their neighbors for help. In one study, researchers prevented a flycatcher pair from aiding their neighbors when an artificial predator was placed in the area. When that pair alarm-called in the next round, the neighbors did not respond. Apparently, birds take note when others don’t pull their weight in a group. It pays to cooperate.

Celebrating The 40th Anniversary Of The Endangered Species Act: Northern Spotted Owl Continues To Decline

At one time, the Northern Spotted Owl was found in old-growth forests throughout the Pacific Northwest. Heavy logging and other developments over the last 190 years have reduced spotted owl habitat by 60%. As a result, owl numbers have declined by 40%–60% in the last 10 years, leaving an estimated 2,000 pairs in existence today.

Celebrating the 40th Anniversary of the Endangered Species Act: Greater Sage-Grouse Losing Ground in Effort to Survive

It’s 6:00 a.m. and still dark when we arrive at the Millican lek, just east of Bend. Even in the predawn darkness of this early May morning, we can hear the “thump-gurgle, thump-gurgle” of the male Greater Sage-Grouse as they try to impress the females. The elaborate courtship display goes on for an hour and a half until the birds finally settle down in the full light of day, and it will continue every morning for another month as the sage-grouse work out their relationships.

This fascinating ritual is becoming increasingly rare in Oregon and across the West as development, livestock grazing, wildfire, and other environmental impacts reduce sage-grouse habitat.

Conservation Column Nov 2013: Empathy: Not Just for Humans

Imagine: You watch a friend get into a heated argument with someone. Afterward, you think your friend must be feeling bad, so you spend some time consoling him in the hope of making him feel better. Scenarios like this probably seem commonplace to you, and you are likely not surprised that such behavior occurs. But many people are astonished to learn that a goose or monkey might display similar behavior. It was long thought that people were the only animals that could understand the minds of others and respond as if they knew what others were thinking or feeling, a trait often dubbed empathy. Scientists have devised studies to demonstrate this ability in nonhuman animals and have shown that we are not the only ones that display empathy. Many of these studies featured our closest relatives, chimpanzees and other primates, but researchers have found intriguing evidence that birds have this ability as well.

Celebrating the 40th Anniversary of the Endangered Species Act: California Condor Still Critically Endangered

The California Condor, like the Bald Eagle described in the May-June issue of The Quail, was placed on the endangered species list almost half a century ago. But unlike the Bald Eagle, the condor is far from recovered.

Conservation Column Oct 2013: The O&C Trust, Conservation, and Jobs Act

The O&C lands consist of 2.8 million acres of public land in western Oregon. Originally given to the Oregon & California (O&C) Railroad Company in 1866, they were put into the public trust under federal management in 1937. Even after years of timber harvesting, these lands represent some of the best mature and old growth forest in the western United States. Counties with O&C lands received money when the forests were logged, and they came to rely on these funds. In 2000, the struggling counties began receiving federal funds, which continued each year to give them time to develop better economic models. Unfortunately, they did not do so, and the counties are now in crisis...
