Wolves were more likely than humans to kill older and juvenile ungulates, reflecting a difference in selection patterns. Comparisons of wolf prey selection versus prey selection by hunters were made using species, age and sex. Prey selection by colonizing wolves were also compared with those from known wolf populations. Characteristics from 243 prey killed by colonizing wolves during the winters of 1985-1991 were examined and compared with those of ungulates killed by hunters. Research found that wolves killed a larger proportion of white-tail deer (Odocoileus virginianus) fawns (P< 0.05) and elk (Cervus elaphus) calves (P< 0.05) than did hunters. Wolves also selected older white-tail deer and elk more than hunters. Males were also killed at a disproportionally higher rate relative to their occurrence. Colonizing wolves tended to kill a higher proportion of fawns and calves versus the established wolf populations elsewhere.
