Factors influencing caching behavior of red squirrels (Tamiasciurus hudsonicus) were studied in Pattee Canyon, Lolo National Forest, Montana. Tamiasciurus hudsonicus in this population cache ponderosa pine (Pinus ponderosa) cones and Douglas-fir (Pseudotsuga menziesii) cones in multiple caches of varying size. In comparison with randomly-selected, potential cache sites, caches were associated with soft soil and were near T. hudsonicus nests. Frequency of cache use was not significantly correlated with any measured attribute of caches. The use of multiple caches in this population may be a response to feeding on non-serotinous cones, which must be cached quickly.
