　　The objective of this study was to evaluate how northern flying squirrels (Glaucomys

　　sabrinus) locate truffles (Gautieria monticola), a subterranean and ephemeral but primary food

　　source. Thus, we evaluated the importance of three factors to the foraging behavior of

　　northern flying squirrels: (i) olfactory chemicals that emanate from truffles; (ii) the presence of

　　coarse woody debris (decaying logs), which are often associated with fungi; and (iii) we

　　explored the potential role animal memory could play in truffle detection as well. In a foraging

　　arena, squirrels successfully retrieved buried truffles that lacked aboveground cues in 19 of 30

　　trials and failed to search near treatments that lacked truffles altogether, confirming the

　　importance of olfaction to squirrel foraging. However, squirrels also retrieved truffles that were

　　associated most frequently with surface logs (27 of 30). In addition, the initial detection rate of

　　the truffle + log treatment was significantly greater than the truffle-only treatment. Thus,

　　although squirrels search for truffles primarily using olfaction, they may also benit by

　　searching near coarse woody debris on the forest floor as an aboveground cue to truffle

　　locations. In addition, because 82% of Sierra Nevada truffle-fruiting locations that were marked

　　in 1996 yielded truffles again the following 2 years, mycophagous animals like northern flying

　　squirrels may benit by memorizing fruiting locations and foraging at these same locations

　　from year to year.
