Emily Gibson discovered this active black-backed woodpecker nest while she and I were teaching a program in the Salmon River Mountains of central Idaho.
While researching and writing my field guide I encountered various published accounts of the foot structure of mink (Neovison vison). Because of these discrepancies I sought out specimens to examine personally. I examined the feet of 3 recently deceased mink, all from western Washington as well as about a dozen museum skins at the Burke Museum at the University of Washington. All of the green specimins I examined showed mesial webbing on both front and hind feet. Some of the museum skins did as well, while others where dried in such a way so as to make analysis of this impossible. None of the green specimins or museum skins were clearly lacking webbing between toes. The amount of webbing is slightly less than in their larger cousins, river otters (Lutra canadensis) but is none the less quite clear. As is typical with the tracks of most web-footed animals, webbing can be detected in footprints in deep substrates but is often not apparent where substrate is firmer.The photos of actual feet bellow are from a male mink which was killed by a vehicle in the Snoqualmie River Valley, King County, Washington in 2009.
A week of journeying by land and sea has yielded some great results as I continue to collect material for my forthcoming book on Wolves of the Pacific Northwest. I am tremendously grateful to Steve and Susanne Lawson for their invaluable assistance in my fieldwork here in Clayoquot Sound thus far! Stay tuned for more photos and stories to come!
“Dave- I checked the White Pine camera on Sunday the 20th after two weeks, got about 640 shots of a Pine Marten, two grey jays, and a few wind triggers. I replaced the batteries, card, bait and scent. It only took that Marten two days to get all the bait.”–Pete Jenkins
This weekend, following up on several sets of likely wolverine tracks biologist and backcountry skier Pete Jenkins discovered, a small group of intrepid citizen scientists set out to place a remote camera in the vicinity in hopes of capturing a photo of the illusive carnivore. Grey skies and a very thin coat of fresh snow beckoned.Clouds covered the high peaks of the Chiwakum mountains south of Highway 2 in the Washington Cascades when the group met early Saturday morning. For the project, a few unusual items were called for, not usually included in the field kit of backcountry skiers: a hammer, some chicken wire, a motion sensitive camera, and, much to my chagrin, a frozen chicken and the contents of the scent glands of a beaver (these two items ended up in the bottom of my backpack). More typical of such a ski trip, Samantha Goff insisted on the addition of a can of Pabst Blue Ribbon Beer to each of our packs (see my blog post on climbing around the Eldorado Massive, http://davidmoskowitz.blogspot.com/2009/08/climbing-in-north-cascades.html, for background on Sam and PBR).We departed bright eyed and bushy tailed as heavy wet snow fell, providing some reprieve from the hard raincrust. A couple of hours later, a gain of 2000′ elevation, skinning on an old logging road and then up through uncut mixed conifer forest, had left us quite wet and me feeling a bit upset about the freeloading chicken weighing me down.Pete identified the location he had determined would be the best spot to set up the camera based on prievious track sightings and how animals general moved across this particular set of drainages descending from a large alpine cirque above. Not a minute too soon. I was totally fed up with my chicken (and had a sneaking suspicion it might be leaking chicken juice into my pack.

Despite decades of conservation efforts, Clayoquot Sound, a UNESCO Biosphere Reserve, faces numerous severe threats to its ecological integrity including clear cut logging of roadless old growth forests, industrial Atlantic salmon fish farms, and proposed open-pit copper mining.
