Golden Eagles: An Exercise in Patience

I recently traveled with a few colleagues to north-central Baja California, Mexico, to conduct field research for the San Diego Zoo’s Golden Eagle Project (see previous post, Golden Eagle Helicopter Survey). A wind farm is being designed for future development in the Sierra Juarez, and the San Diego Zoo is involved with pre-construction research of habitat use and demographics of golden eagles. The objective of the project is to examine what parts of the mountain range are used by eagles and how and when they use each part. Our findings may help to minimize future interactions between eagles and turbines.

Hope for Polar Bears

Posted at 8:26 pm November 8, 2009 by Ron Swaisgood

What I want to talk about to today is hope—hope for conservation, and hope for our planet even though it is facing unprecedented environmental challenges. I’m in Churchill in Manitoba, Canada, working with friends and collaborators at Polar Bears International. It’s a surreal experience going out on the Tundra Buggies and seeing wild polar bears. But underneath this joyful experience there is also sadness, because I know that this “polar bear capital” may one day have no polar bears. By now, most of us know that the polar bears are losing their sea-ice habitat and here, at the southern end of their range, they will disappear first. We’ve already lost almost a quarter of them in the past 15 years. In another 15, there may be no polar bears left in Churchill.

Reaching Out for Polar Bears

This really is shaping up to be an amazing experience. Each day I go out on the Tundra Buggy, run by Frontiers North Adventures. Oh, and by the way, they are giving us a free pass on the Tundra Buggy and a room in the Tundra Lodge. They like what we are doing, trying to bring more attention to the plight of the polar bear. And it’s hard to imagine a species more deserving of attention than polar bears. They are the world’s largest terrestrial carnivores, and they are impressive.

Bear Culture

In my last post, I rambled on about why conservation of Andean (or spectacled) bears, and conservation in general, matters, from a scientific viewpoint. This time around I’ll wade into some of the other reasons we work for conservation.

The e-mail that started me on these two posts highlighted a Web site showing some hunters with big game “trophies.” In this case, the trophies were taxidermy mounts of large mammals, mostly carnivores. In the background was a stuffed Andean bear, and the presence of this stuffed bear disturbed the e-mail’s writer and at least some of its readers.

The Polar Bears of Churchill

Posted at 3:21 pm October 30, 2009 by Ron Swaisgood

One of my first wild polar bears here at Churchill. Thin at this time of year, waiting for the ice to re-freeze so they can hunt, they are still large and powerful predators.

I saw a bear. Okay, I saw six. And it only took a couple of hours. I’ve been working with bears for many years now, and this is not what I’m used to. I’ve worked most extensively with giant pandas, and it took me years to see a panda in the wild. Recently, I started working with Andean (or spectacled) bears and, with a lot of sweat and hard work (and the help of an experienced collaborator), managed to see ONE in Peru (see post The Bear Goes Over the Mountain). But here, polar bears are everywhere! For now.

I’m in Churchill, Manitoba, Canada, known as the polar bear capital of the world. I’m here as a guest of my friends and collaborators (and supporters!) at Polar Bears International. This is a terrific organization, and they have given me a terrific opportunity. More on that later. The bears are beautiful! I can’t wait to share more about the bears in my next posts.

Tortoises on TV

KVBC Channel 3 shot their morning show “Waking Up with the Wagners” live from the Desert Tortoise Conservation Center (DTCC) today! Mojave Max and Ethel (see post Desert Tortoises: Lucy and Ethel) made their final appearances of the season. It’s cold here in the Las Vegas Valley, so they will soon be settling in for their winter brumation.

We also introduced a family of 18 tortoises, ranging from hatchlings to adults, that all came to us through our Desert Tortoise Hotline from the same home and were not in very good health; it gave us the perfect opportunity to encourage people to surrender their pet desert tortoises to the Clark County Desert Tortoise Hotline here in southern Nevada so we can rehabilitate the tortoises and eventually release the healthy ones into the desert to help recover the species. We are confident that all 18 tortoises will be successfully rehabilitated by this time next year, and maybe even sooner.

Bear Care in Conservation Terms

Russ Van Horn is currently in Peru to study Andean (spectacled) bears. Read his previous post, Andean Bears and Cameras.

An e-mail was posted recently on the Andean bear e-mail network that got me thinking about the question “Why do we care about Andean bears?” I realized that I was not only thinking about this question, but also pondering “Why do we care about the conservation of nature?” I’m not sure I can clearly answer these questions, and I’m sure I won’t say anything that hasn’t been said before by someone else, but here goes. In this post I’ll focus on the reasons for (bear) conservation presented from a scientific viewpoint, but there are other reasons for caring about conservation. I’ll write about those in my next post.

Roo Rats Released!

Last week we released the second group of 50 kangaroo rats (see previous post, Kangaroo Rats Keep Us Hopping). We placed sand scented with mountain lion pee at scent stations for 25 of them. The other 25 were among sand piles wet with water. We are using remote cameras to take still and video images of any predators that visit the site.

The Bear Goes over the Mountain

San Diego Zoo researchers are in Peru to study Andean (or spectacled) bears. Read a previous post, To See A Bear.

We awake in the predawn twilight, rouse ourselves out of our sleeping bags, down some coffee, and head for the viewpoint, hoping to spot last night’s bear making the ascent back up from the waterhole. José begins to gesticulate wildly, pointing to a dark form moving slowly up the face of the cliff.

To See a Bear

It’s early morning, and the cool night air quickly burns away as the sun appears above the ridge of the mountain to the east of the camp. The light that accompanies the heat, however, reveals a spectacular scene. Still in my sleeping bag, I sit up and admire the view. Across a narrow valley, sheer cliffs drop down from the ridge and disappear below. A few somewhat gentler slopes support some vegetation. Javier points out an orange-ish post among the small trees: a posayo tree, reduced to a shattered stump by a foraging Andean (spectacled) bear.
