A Record Large Wolf, Canis Lupus, Pack In Minnesota, L. David Mech
A Record Large Wolf, Canis Lupus, Pack In Minnesota, L. David Mech
USGS Northern Prairie Wildlife Research Center
This report documents a pack of 22-23 Wolves (Canis lupus) in central Minnesota. This is larger than the largest pack previously observed on the mainland in the midwestern U.s. during 650 wolf pack-years. Because this record-large pack preyed on White-tailed Deer (Odocoileus virginianus), one of the Wolfs smaller prey, it is evidence that pack size and prey size are not tightly related. It also indicates the size that Wolf packs can attain in the area if fully protected from human persecution.
