Post-Natal Survival Of Raccoons In Relation To Female Age And Denning Behavior, Jonathan J. Judson, William R. Clark, Ronald D. Andrews
Journal of the Iowa Academy of Science: JIAS
We measured post-natal survival of radio-collared raccoons 1-5 months old in southwest Iowa, 1988-1989. We compared survival of young nurtured by yearling and adult females and related den site selection to survival functions using proportional hazards models. Adult females used upland and farmstead habitats note frequently than yearlings, whereas yearling females used lowland habitats note frequently. Tree cavities and beds on the ground were used most frequently. Adult females denned in buildings 13% of the time and in holes in the ground 9.5% of the time, whereas yearlings frequently tested with litters in beds on the ground (31%).
