Foraging ecology of coyotes (Canis latrans): the influence of extrinsic factors and a dominance hierarchy

摘要: We examined the influence of intrinsic (age, sex, and social status) extrinsic (snow depth, snowpack hardness, temperature, available ungulate carcass biomass) factors in relation to time–activity budgets coyotes (Canis latrans) Yellowstone National Park, Wyoming. observed 54 (49 residents from 5 packs, plus transients) for 2507 h January 1991 June 1993. Snow biomass, habitat type influenced amount time rested, travelled, hunted small mammals, fed on carcasses. Coyotes decreased travelling hunting increased resting feeding carcasses as snow depth biomass increased. Age status coyote activity budgets. During times deep high pups less mammals more than alpha beta coyotes. Pups apparently were restricted by older pack members a carcass. Thus, adopted different foraging strategy ...
