Hoary Marmots Attracted to Human Urine Sites
Northwestern Naturalist, 1989Accounts of foraging behavior in hoary marmots (Marmota caligata) show very similar patterns in colonies from Alaska (Hansen 1975; Holmes 1984a), Montana (Tyser and Moermond 1983), and Washington (Barash 1973,1974; Taulman 1975). All members of a colony have equal access to foraging areas as a result of the high social tolerance between colony members (

The distribution and taxonomic status of the Alaska marmot (Marmota broweri) have been the subject of much debate and confusion since the taxon was 1st described as a subspecies of the hoary marmot (M. caligata). As a result of its early association with M.

Predation risk for hoary marmots in Washington’s North Cascades Mountains
Journal of MammalogyAbstract Declines in populations of small mammals associated with high elevations, e.g., marmots (Marmota spp.) and pikas (Ochotona spp.), have been attributed to both direct and indirect effects of environmental changes caused by humans. For example, populations of Olympic marmots (M.

The social behaviour of the hoary marmot (Marmota caligata)
Animal Behaviour, 1974Abstract The social behaviour of four colonies of hoary marmots (Marmota caligata) was studied in Glacier National Park, Montana, during the summer of 1970. Colony structure involved a dominant male with a few females (3 years or older), 2-year-olds, yearlings and pups.

Mate guarding and gallivanting by male hoary marmots (Marmota caligata)
Behavioral Ecology and Sociobiology, 1981Seven years data on the vernal behavior of hoarty marmots, Marmota caligata, suggest that males engage in a two-part reproductive strategy, which consists of guarding their mates against possible copulation with additional males, and also gallivanting — wandering about in search of additional reproductive opportunities for themselves.

The influence of reproductive status on foraging by hoary marmots (Marmota caligata)
Behavioral Ecology and Sociobiology, 1980Predictions were made and tested, comparing the foraging behavior of reproductive (rf) and nonreproductive (nrf) female hoary marmots, with the following findings: In June, no differences occur between rf's and nrf's, regarding daytime foraging. However, rf's forage more in the evening and during inclement weather, suggesting that greater nutritional ...
