Predation is an important cause of mortality for mule deer fawns (Smith and LeCount, 1979; Steigers and Flinders, 1980; Hamlin et al., 1984), and fawn survival might be related to characteristics of fawn bed sites (Huegel et al., 1986). Vegetation, through its influence on doe nutritional condition and fawn concealment cover, may be an ultimate factor in fawn survival (Knowlton, 1976; Robinette et al., 1977). Coyotes (Canis latrans) generally rely on visual cues to locate prey (Wells and Lehner, 1978); increased vegetative cover could reduce their ability to locate and kill fawns, especially during the first few weeks when fawns spend approximately 90% of their time bedded (Jackson et al., 1972). Thus, the bed site chosen is important in determining the fawn's vulnerability to coyotes and other predators. This study describes mule deer fawn bed sites in a pinyon (Pinus edulis)-juniper (Juniperus monosperma)/shortgrass prairie habitat on the Pinon Canyon Maneuver Site (PCMS), Colorado. We tested two null hypotheses: 1) characteristics of mule deer fawn bed sites and random
