In fact, Great Horned Owls began nesting at the onset of this cold snap. Our female at the ORI field station began laying eggs and incubating. For almost a week the temperature dropped from about 20 degrees F to 10, then 0, then minus 10, minus 15, and eventually minus 28 degrees below zero. Meanwhile, the male roosted nearby and provided his mate with food while she incubated eggs. Eventually, the pair raised three young to fledging. Our group was able to see the entire family. By late February to early March, an influx of Short-eared Owls occurred. I had never seen anything like it. Hundreds of Short-eared Owls arrived in the valley. Flocks of 15, 20, 35, 50, and 70 were regularly reported by ranchers, birders, photographers, and others. And, in one evening I counted 90, of which 73 were roosting on fence posts and counted at one time. By mid-to-late March, however, except for Great Horned Owls, other owl species numbers dropped significantly. We found only one individual Long-eared Owl and zero nests in our Missoula study site. It’s been many, many years since we have not found a nest in Missoula.

  • Fur Color Diversity in Marmots
    Ethology Ecology & Evolution 21: 183-194, 2009 Fur color diversity in marmots Kenneth B. ArmitAge Department of Ecology and Evolutionary Biology, The University of Kansas, Lawrence, Kansas 66045-7534, USA (E-mail: [email protected]) Received 6 September 2008, accepted 19 May 2009 Fur color that differs from the typical shades of brown and gray occurs in eight species of marmots. Albinism generally is rare whereas melanism is more common. Melanism may persist in some populations at low frequencies averaging 16.1% in M. monax and in M. flaviventris for as long as 80 years. White (not albino) and “bluish” marmots generally are rare, but a population of white M. marmota persisted for at least 10 years. Four species are characterized as having pelages of “extreme colors”; M. caudata, red; M. vancouverensis, dark brown; M. caligata, white; M. bai- bacina, gray. Fur is involved in heat transfer between the marmot and its environment. Heat transfer depends on fur structure (fur depth, hair length, density, and diameter), on fur spectral properties (absorptivity, reflectivity), and on the thermal environment (temperature, wind speed, radiation). Heat transfer is highly sensitive to solar radiation. Metabolic rates calculated from the fur model corresponded closely with measured values at ambient temperatures ≤ 20 °C. Solar radiation can either provide heat that could reduce metabolism or thermally stress a marmot. M. fla- viventris orients towards the sun when solar radiation is low and reduces exposure when it is high. Light fur reduces and dark fur color increases absorptivity. I hypothesize that fur color functions primarily in heat trans- fer.

    HOARY MARMOT Scientific Name: Marmota caligata Species Code: M-MACA Status: Yellow-listed Distribution • Provincial Range In British Columbia the Hoary Marmot occupies most of the mainland except for the northeast and low elevations in the dry interior. • Elevational Range: Timberline to Alpine • Provincial Context The Hoary Marmot is common in the high elevation, mountainous areas of the province. • Project Area: Ecoprovince: Southern Interior Mountains Ecoregions: Columbia Mountains and Highlands, Southern Rocky Mountain Trench Ecosections: Eastern Purcell Mountains, East Kootenay Trench Biogeoclimatic Zones: ESSFdk; ESSFdkp; ESSFdku; ESSFwm; ESSFwmu; ESSFwmp; AT Ecology and Key Habitat Requirements The Hoary Marmot inhabits high elevation meadows and talus slopes near timberline. They feed on a variety of herbaceous plants found in alpine and subalpine meadows. They can also be found in habitats with large boulders which they use to watch for danger and stretch out and sun themselves (Banfield 1981). They spend the majority of the year in hibernation in burrows beneath the grounds surface. These burrows are also used for security cover and cover from thermal extremes. Their dens may be found under the edge of a rock slide or in open hilly ground under a large boulder or in loose talus. They also use these dens as a nest for young which are born in late May or June. The dens are lined with grasses which are replaced every spring with fresh grasses. Habitat Use and Life Requisites The life requisites that will be rated for Hoary Marmot are: living and hibernating which are described in detail below. • Living Hoary Marmots live in open sites with lush plant growth and good visibility to see one another or detect predators.
