Homesite attendance was monitored in a gray wolf population with high moose density and a population with low moose density, Isle Royale National Park (MI) and Kenai National Wildlife Refuge (AK), respectively. Ten wolves (five in each area) were monitored for a total of 114 weeks during the summer denning period. Annual variation in attendance for individual wolves was high even where prey density was stable. Factors that may outweigh prey density in influencing homesite attendance include age, breeding status, and intrapack social relationships.
