Burrowing Owls

It's hard to deny: Burrowing owls are cool.

And while that might not be objective, how else to describe a soda pop can-sized owl that lives underground?

Last evening, Katie McVey, environmental education specialist for the Deer Flat National Wildlife Refuge, presented a program on her burrowing owl research to the Golden Eagle Audubon Society.

Katie and others have studied these owls at the Morley Nelson Snake River Birds of Prey National Conservation Area for years by building artificial dens and conducting extensive research on nesting success, diet and owl habits.

The Snake River area has one of the highest densities of burrowing owls in the country, creating an excellent environment to learn more about these curious creatures.

The owls have very interesting habits. They move into abandoned holes dug by badgers and other mammals, and hatch large broods of chicks (one in the area hatched 16).

They feed on a variety of smaller critters, including mice, voles, scorpions, grasshoppers and small snakes. They catch as much as they can and deposit an extra prey underground in a cache, to be eaten when the hunting isn't as good.

Owls may be doing well in Idaho, but lots of owls are living near agricultural fields which raises some conservation concerns. Can they thrive alongside agriculture? Does this expose them to new dangers? What if those farms are developed? These are all questions being explored by the researchers.

About 95% of Idaho's burrowing owls migrate, most likely to southern California, for the winter. Some are already showing back up at the Birds of Prey area, according to local birders.

They are found in grassland areas of the United States as well as Central and South America.

In fact, I took these photos on the expansive Llanos grasslands of Colombia, where the owls were amazingly abundant. Riding horseback across the plains, it was not unusual to encounter dozens of them. Every time I encountered them they made me smile--with their big eyes and curious look.

Unlike almost all other owls, burrowing owls are active during the day. So keep your eye out in southern Idaho this spring: you might just be rewarded with a sighting of this interesting little bird.--Matt Miller

Kent Christopher Memorial

Sagebrush country has long been considered under-appreciated: After all, many drive through southern Idaho at 80 mph and see nothing but a barren, empty land.

Kent Christopher knew better, and wanted to show others the wild side of this open land: dancing grouse, beautiful wildflowers, racing pronghorns, the opportunity for incredible outdoor adventures.

A new memorial (above) at Camas National Wildlife Refuge will remember Kent's many contributions to sage grouse and sagebrush habitat conservation. (Click on the image for a larger version).

Kent was a passionate falconer, conservationist, educator, poet and photographer. His connection to the land was formed by flying his gyrfalcons on sage grouse, but he loved it all: the birds, the ranches, the country.

Kent worked closely with The Nature Conservancy at Crooked Creek Preserve, and created the first-ever Dubois Grouse Days, an event that offers tours to see sage grouse on their spring breeding grounds (called leks). The event has become tremendously popular and is a great way to see this natural spectacle in all its glory.

This year's Grouse Days will be April 16 and 17. Kent's memorial will be dedicated during the event.

Kent was tragically killed in a ski accident in March 2008, much too soon. We need more like him. In eastern Idaho, his legacy lives on. Long may his work serve as an inspiration to the falconers, birders and conservationists continuing the hard work of protecting and restoring sage grouse and sagebrush.

Support Idaho's State Parks

The Nature Conservancy supports an adequately funded, professionally managed state parks department in Idaho. These parks provide so much for our quality of life: world-class outdoor recreation, affordable places for families to spend time outside, abundant wildlife, beautiful scenery, historic preservation.

That's why we're happy to see a strong grassroots effort forming by those who love our parks: the Friends of Idaho State Parks.

The best way to get involved right now is by becoming a Facebook fan of Friends of Idaho State Parks. The Facebook page contains a lot of great information on how to help and how you can best be an advocate for our parks.

Become a fan today and show your support!

Tundra Swans are Here

The tundra swans have really been showing around Idaho in the past week. They'll stop for a bit before heading north to their breeding grounds on the Arctic and sub-arctic tundra.

The calm waters provided by wetlands offer an excellent pit stop before continuing on a long journey.

While the tundra swan population is estimated at 170,000 birds, they seem to be in a slow decline in the western United States.

Polluted water--which causes declines in the aquatic vegetation on which they feed--is suspected as a major culprit in the decline.

If you want to see swans in Idaho, here are some suggestions:

Reviews: Feathered Obsessions

I love identifying and observing birds, but I admit that I've never been interested in competitive listing--ticking off bird species seen for the purposes of amassing a long "life list." In its most extreme forms, listing seems to reduce the beauty of birds to mere tokens to be collected, while ignoring their habits and the stunning places they inhabit.

Most birds about competitive listing similarly leave me cold; these stories too seem more about numbers than birds.

But not this one: Olivia Gentile's Life List is a compelling portrait of Phoebe Snetsinger, a woman who took to birding to escape a life she considered mundane, and from there became the first person to see 8000 of the world's bird species.

Snetsinger makes a fascinating character. As a young woman in the '50s she aspired to be a scientist, but instead fell into the expected roles of housewife and mother. She turned to birding as an escape, becoming ever more passionate about recording birds she'd seen.

In 1981, at the age of 49, diagnosed with cancer and given a year to live, Snetsinger set out on a string of international birding tours to see as many species as she could before she died. She lived another 18 years--and in that time accumulated a life list larger than any other birder.

Gentile presents a complex story of a complex individual. It's hard to not admire Snetsinger, a woman who at times braves terrible conditions and rugged travel to add a few birds to her list. But the other side of obsession is also here: the toll on her husband and children, the increasingly competitive nature of her birding, the neglect of her mental health following a horrific assault on a birding trip in New Guinea.

Best of all, Gentile also captures the genuine thrills of seeing new birds in their habitat. This ultimately, is not a story about numbers, but of birds--and the great places birds can take us.
Falconers have their own breed of feathered obsession. The art of hunting game with trained birds of prey is an ancient pastime, and given the inherent difficulties of training a raptor coupled with the strict regulations and apprenticeship process, it's nearly impossible to be a casual falconer.

Rachel Dickinson's Falconer on the Edge is her attempt to understand what drives falconers in their passion. Married to falconer Tim Gallagher--the writer and naturalist who rediscovered the ivory-billed woodpecker--she decided to learn about her husband's passion by spending time with one of the sport's most fanatic devotees.

Steve Chindgren flies his falcons on sage grouse at least five days a week in the autumn and winter near his cabin in Wyoming. Sage grouse hawking is considered one of the most beautiful and difficult forms of falconry.

In her book, Dickinson captures the many elements that add up to make a falconer--the raptors, of course, but also the sage grouse, the land, the regulations, the camaraderie.

As any book involving sage grouse today must be, it's also about conservation--especially as so many of Chindgren's hawking grounds are overtaken by energy development on Wyoming's sagebrush country.

Falconers have a long history of conservation, including the highly successful restoration of peregrine falcon populations. They pursue conservation with the same obsessive nature as they do hunting.

Falconers have already become heavily involved in sage grouse conservation, in places like Idaho's Crooked Creek. We'll continue to need their help as we work to stem the decline of sage grouse populations.

Obsession can mean many things, not all of them positive. But a close connection with the natural world--be it through birding or falconry or another activity--inarguably also makes the strongest conservationists. --Matt Miller

Badger Ambassador

Badger posts always generate a lot of interest on this blog, so I thought I'd share this unusual photo of a badger on a leash.

No, it's not a pet, but a rescued badger at the High Desert Museum near Bend, Oregon.

Badgers are common in sagebrush country, but can be difficult to find. I recently hosted a naturalist trying to see all the world's mammals who came to Idaho to try to see a wild American badger. He has seen pandas and clouded leopards and all manner of rare and elusive animals, but no American badger. He finally found one at the Snake River Birds of Prey Conservation Area--but it took a lot of patience, careful searching and spotlighting.

Idaho has the highest density of badgers on earth. Still, most kids won't see one unless they're lucky. The badger at the High Desert Museum offers an up-close look at this cool mammal. Hopefully it can instill curiosity and interest in badgers, and their sagebrush home.

Watch a video about the museum's badger.

Wood River Valley: Mountain Lion Encounter!

Story and photo by Sara Sheehy, donor relations manager in the Conservancy's Hailey office.

I told my friend I had “quite the story to tell.” He retorted by saying “Quite the story to tell – that was the understatement of the decade.” I so rarely tell stories here, but this one is a good yarn.

And it’s all true.

I woke up this morning in a scream. I couldn’t figure out why, until I focused enough to hear the howling and snarling outside the window. My first thought was that a fox or coyote was after one of the barn cats, and that our neighbor’s dog was fighting it off. I sensed a faint scuffle happening near the barn but it was too dark to see.

After dragging Mike out of bed, we grabbed a flashlight and headed outside. My main concern was that there might be an injured cat in the yard.

Just outside the barn we came across a sizable patch of blood.

I heard a faint noise, and something rushed out of the darkened barn towards us. I screamed, and shone my light on what turned out to be my neighbor's dog. She didn’t come near us, but I started to worry that it was her blood we had seen.

I called the neighbors in my concern, and shortly all the lights went on in their house. I proceeded to get ready for work. As I was walking through the living room, out of the corner of my eye, I saw a large shadow lurking on the side of their house.

My first thoughts were “No way. It couldn’t be. It just couldn’t.” The shadow turned its big head in the reflection of light against snow and I couldn’t deny it. Cougar.

After calling my neighbors again to warn them to stay inside, a car pulled into the driveway. A woman I didn’t recognize got out, unaware that she was 20 feet from the shadowed cougar. The cougar crouched.

I panicked, flung open the window, and yelled at her to return to her car. She moved her headlights to flash at the house. The mountain lion stood up, turned, and stalked away.

The woman left, with our neighbor’s dog (and the neighbors) a short time after. Once it was fully daylight, I returned outside and hunted down the large paw tracks. The one pictured above was behind the barn.

The circumference of the paw print was bigger than my palm, but smaller than my fully extended hand. A big cat.

The happy ending to this story is that the dog is recovering from her run-in with the cougar, and we are hopeful that the one missing barn cat will return (barn cats have a tendency to disappear occasionally, and they are great hiders).

I am grateful that when I went out to investigate the “fox” this morning, that it was only the dog that came out of the barn, and not the cougar, too.

I live in a very narrow valley where large animals are feeling the constant pressure of fragmentation and development where they once traveled.

It is a constant struggle in these situations to do what is best for humans and animals, while remembering that we as humans have invaded their home. I don’t yet know what the resolution in this particular situation is, but it is never easy.

For now, I will be keeping my two dogs close at hand and being careful not to venture outside during dawn and dusk. I hope the cat got a healthy scare and will move into a more wild locale. I hope that for the cougar, and for us.

The Goshawk

Blog by Dayna Gross, Silver Creek Preserve manager

One of my favorite times of the year, winter at Silver Creek inevitably brings with it a rare bird sighting or two.

I am always quick to point out to people that the winters, although quiet, are quite busy with wildlife. It seems that all the critters congregate at Silver Creek for the open water, the shelter, the midge hatches, and the abundant rodents.

This year, we had a barn owl at the visitor center for a few weeks--scaring the hunters first thing in the morning.

Last week I was told a great Silver Creek story--- the remarkable story of a bird that came to Silver Creek during the winter from hundreds of miles away. It appears that this journey may have helped make her one of the longest lived northern goshawks on record.

Jack Kirkley, biology professor at the University of Montana, trapped this goshawk at her nesting site in the Big Hole Valley in southwest Montana in 2003. The tag led him to find that she was originally banded by a Boise State University graduate student in 1991.

After a tip that she was seen around the Silver Creek area in 2004, Jack drove down here and confirmed that it was the same bird.

He has since lost radio contact and believes she is probably dead. Fourteen years and four months is a very long run for a goshawk, though.

When I asked him the normal age range for the bird, he told me that he sees a lot of one and two year olds die from starvation in the winter and most don’t live past five or six.

He thought that she travelled all the way from the Big Hole Valley to Silver Creek in the winter and speculated that this may have been the reason for her living so long—winter site fidelity.

For me, this story really struck a chord. I think of the mountain ranges she would have had to cross just to get here.

And, why here? Of all the places, I wonder why she chose Silver Creek.

It is in my nature to be a little imaginative, so my guess is that she was drawn here, like we all are, because it is such an awesome and remarkable place! (With lots of rodents, of course).

Birds on Open Water

With ponds and lakes frozen, one of the best places to look for birds is wherever you find open water. Silver Creek Preserve, the South Fork of the Snake, the Boise River, the Salmon River and its tributaries and the Henry's Fork are just a few places to check out for excellent winter birding.

Flocks of waterfowl congregate at deep river pools; you'll see many species now that can be difficult to spot in large flocks at other times of year. Look for American and Barrow's goldeneye, bufflehead (pictured above) and other diving ducks. Gadwalls, green-wing teal and widgeon also spend the winter on Idaho's rivers.

American and hooded mergansers are a common sight. These birds are fun to watch as they dive under water and come back up with whitefish and small trout. At times, a merganser will seem to swallow a ten-inch or longer fish, which seems a difficult feat for a bird of that size.

In East Idaho, trumpeter and tundra swans make a dramatic sight as mist rises on the Henry's Fork and South Fork.

It's probably the best time of year to see bald eagles. I've seen as many as six along the Boise River while sitting quietly there in the early morning. While in Coeur d'Alene last week, many nature lovers reported seeing a lot of eagles around Cougar Bay.

Willows and other vegetation along streams are alive with black-capped chickadees, red-shafted flickers and many other birds. In the early morning and at dusk, great horned owls--hooting as the begin to nest--can often be seen silhouetted on tree branches.

So take a walk along a river or stream this winter--the birds are there in abundance.

Hogs in Idaho, Hippos in Australia

Recently, I reported here on the confirmation of feral hogs in Idaho, a most unwelcome announcement.

Now comes the strange case of a pygmy hippo roaming freely in Australia.

Welcome to the strange new world where we never know what animal might show up in your backyard. Read more on my blog at Cool Green Science.--Matt Miller

A Stanley Bird Journal, 1971-1983

Last week, The Nature Conservancy's Idaho field office received via mail an interesting notebook from 83-year-old Betty Jo Olson of Twin Falls.

Betty was doing some house cleaning and thought we might be interested. Her little notebook details all her bird sightings from 1971-1983, while living in a trailer in Stanley.

She certainly saw a lot of birds, from Audubon warblers to ouzels to golden eagles. She documented when birds like sandhill cranes showed up in the spring, and how long birds like towhees hung around her place.

On an Audubon bird count, she even saw loons on Redfish Lake.

Her notes were sprinkled with colorful descriptions of bird behavior. For instance, here's an entry on a pair of bluebirds: "The female has asked him over to the new house several times, but he seems to want the swallow house. I can hear her saying: I want a 'new' house..."

Betty wondered if her notebook would be of any use. Do such observations help conservationists?

Actually, personal observations of birds and other wildlife are playing an important role to help document population trends, occurences of rare species, appearances of new non-native species and the effects of climate change.

The Cornell Lab of Ornithology counts on observations from thousands of individuals for its Project Feeder Watch and the Great Backyard Bird Count (mark your calendar; this year's count is from February 12-15). Both track long-term trends for bird conservation.

Today in Cool Green Science, the Conservancy's Dave Mehlman shares how birders are being asked to help track sightings of the imperiled--and little studied--rusty blackbird.

Conservation biologists can't be everywhere at once, so observation from citizen-naturalists is a tremendous help.

We always value hearing from nature lovers, friends and members. If you have something you'd like to share, contact the Idaho office nearest you.--Matt Miller

Give Deer a Brake

New signs are being installed on Highway 21, between Boise and Idaho City, urging motorists to "Give Deer & Elk a Brake."

The signs will also include tallies of the number of deer and elk killed on that stretch of road each year.

While this may seem grim, hopefully it gets drivers' attention, and gets them to drive slowly and carefully.

Such signs have been used in many different areas as way to draw attention to big game deaths on roads. (I photographed the sign below in Woburn, England). This is a project of the Idaho Transportation Department, Rocky Mountain Elk Foundation, Idaho Department of Fish and Game and Ada and Boise counties.

The Idaho Department of Fish and Game is also installing a wildlife underpass along this road.

To protect migratory wildlife and wintering big game from the dangers of roads, conservationists must use a variety of methods--habitat protection, overpasses and underpasses, education and signage. Otherwise, we will lose many populations of large mammals. Efforts like these signs are important steps.--Matt Miller

Feral Hogs Confirmed in Idaho

As reported Friday by the Capital Press, the presence of feral hogs has been confirmed in Idaho.

A feral hog was killed in February in the Bruneau Valley of Owyhee County. Trail cameras set up by the U.S. Fish and Wildlife Service have confirmed additional animals present in the area.

Feral hogs are one of the most adaptable and invasive mammal species worldwide. Once established, they are extremely difficult to control. They spread livestock diseases, damage stream habitat, tear up native plants and eat bird nests and native plants.

In many states, isolated reports of feral hogs have led--quickly--to established hog populations that are difficult, if not impossible, to control.

The Nature Conservancy helped lead an effort on Santa Cruz Island off the coast of California to eradicate pigs, which had upset the ecological balance on the island. The pigs attracted golden eagles, which in turn preyed on the native island gray fox--found nowhere else on earth. The pigs were eradicated, and golden eagles were relocated.

But on mainland areas, pigs can be extremely wary and difficult to find. They also have large litters of piglets--allowing their populations to rebound from control measures quickly.

It is believed that hunters introduced feral hogs to the Bruneau Valley from California--a terribly short-sighted action. Such illegal introductions can have long-term impacts on both wildlife and livestock.

The U.S. Fish and Wildlife Service is undertaking a control program this winter, when the hogs will be easier to track. Now is the time to make sure these hogs don't become established in southern Idaho. If you see one, please report it to the Idaho State Department of Agriculture immediately.--Matt Miller

Silver Creek: Year in Review

Submitted by Dayna Gross. Photo by Sara Sheehy.

It’s already winter at the Silver Creek Preserve—the sandhill cranes are long gone and the trumpeter swans are making their winter home here. Waterfowl sparkle on the water and a barn owl is taking care of the rodent problem at the visitor center!

These are some just of the wonders The Nature Conservancy hopes to preserve for future generations.

We are grateful to all our partners in conservation, to all of the landowners who have contributed conservation protection agreements, and to everyone who values the natural world and its many wonders. This year has been remarkable—with a new easement adjacent to the preserve, record student numbers, amazing (although unusual) hatches, great fishing, and high water levels.

Some of the accomplishments in 2009 include:

Molyneux easement: Thank you all for your generous contributions to make this happen! We closed on a conservation easement on the Molyneux property, adjacent to the preserve and visitor center!! We are still raising money to pay for this easement, however, so please donate.

Budweiser Conservation Award: John French was one of four finalists for the Budweiser Conservationist of the Year. John and Elaine French have a property under easement along Silver Creek and have contributed time and resources to make sure Silver Creek remains an amazing and productive spring creek. We will know soon whether he won the Budweiser Conservationist of the Year!

Silver Creek enhancement plan: An effort with our neighbors and partners to better plan and fund restoration work throughout the Silver Creek area is underway. Public meetings will be organized in 2010.

Graduate research: Our graduate student from Montana State, Bri Schultz, who is studying spring creeks and what makes them healthy completed her field work this summer. She will be completing (and presenting) her thesis in the spring of 2010, so stay posted.

Fire restoration: The fence and signs that burned in 2008 were replaced and the seeding that was conducted in 2008 paid off-- you can hardly even tell that 20 acres of the preserve burned. We will be focusing on weed control in 2010 to ensure native plants thrive.

Record student and volunteer numbers: More than 1000 students visited the preserve in 2009. We clocked over 1400 volunteer hours with more than 50 volunteers! In addition, visitor numbers were up slightly this year—right around 7200, with 80% of those anglers.

There are already many activities planned for 2010. Check back frequently for the latest news at Silver Creek Preserve!

Flying Friendlier Skies

Blog by Ginny Glasscock

Everyone appreciates the modern conveniences that electricity brings to our homes, from utilities and communications to entertainment. But we don’t always think about the problems that the equipment that supplies this power can cause for our feathered friends.

Natalie Turlie, of Idaho Power, addresses these concerns in her job as Avian Protection Coordinator. Working with the US Fish and Wildlife Service to monitor problem areas, she then plans improvements to Idaho Power equipment.

She trains company crews to retrofit older poles and lines with more bird-friendly features, and to use these same features on new or replacement installations.

At The Nature Conservancy's Silver Creek Preserve, several power poles were scheduled for replacement prior to winter, as they had been partially charred by the fire of 2008.

Crews recently completed the job, using several bird safety devices. Additional protection was provided on a nearby power pole with three transformers, where an osprey had been recently electrocuted after it perched to eat its meal of just-caught trout.

Birds can run afoul of power lines by actually flying into them, or by electrocution. Natalie explains that birds can die if they simultaneously touch two energized wires, or one live wire and a ground. Birds can perch safely as long as they don’t make these two points of contact.

Protective devices work by making power lines more visible so that the birds can avoid them, discouraging birds from perching in dangerous locations, or by covering energized wires to allow safe perching.

Firefly bird diverters are mounted directly onto long spans of wire in high traffic flight areas. These small, reflective flappers are also luminescent, to be visible to night-time flyers.

Perch preventer strips are rows of small spikes mounted on power pole cross pieces, nudging birds away from dangerous spots. T-shaped perches provide a sitting area well above electrified parts. Large PVC sheaths cover wires and insulators at the tops of poles, and plastic tubing is installed over smaller wires.

You will be able to find all of these on power lines and poles at Silver Creek Preserve.

The preserve is a popular bird-watching destination, with more than 150 different species reported.

All birds and birders are grateful to Idaho Power for their work in mitigating possible conflicts between human needs and avian ones.

Wildlife at Point of Rocks

Conservation Seeding and Restoration, Inc. (CSR) sent this Flickr photo gallery of wildlife on the Point of Rocks section of Silver Creek, on the property of John and Elaine French.

Check out the entire photo gallery.

CSR has undertaken extensive habitat restoration on the Frenches' property, which is also protected through a conservation easement with The Nature Conservancy.

Update on Mercury Levels in Silver Creek Trout

As widely reported today, the U.S. Geological Survey issued a press release explaining that the 2007 report that found elevated mercury levels in Silver Creek brown trout was based on a laboratory error and that mercury levels in Silver Creek are not as high as thought.

The health advisory for Silver Creek trout has been lifted.

At The Nature Conservancy, we're relieved by this news. Obviously, we must continue to monitor trout in Silver Creek for mercury levels, as mercury is still present in these fish.

The Conservancy's Silver Creek Preserve is strictly "catch and release" so the new findings do not change anything on our preserve.

It's important to note that about 2o southern Idaho lakes, reservoirs and waterways still contain mercury advisories--and on many of these waters, people do catch fish for eating.
This is still a serious issue. The Idaho Conservation League has been a leader on addressing mercury in southern Idaho waters, working to educate and advocate for healthy waters.

Wild Idaho fish should be a sustainable, healthful food--not come with health warnings.
