Acorn Woodpeckers (Melanerpes formicivorus) are well known for storing acorns in communal storehouses or “granaries,” which are usually in the trunk and main branches of a large tree. Other locations are sometimes used (e.g., fence posts, eaves of buildings), including sites from which the eventual retrieval of acorns is impossible (hollow trees, through open windows of cabins; Ritter, Condor 23:1-14, 1921; Henshaw, Condor 23:109-118, 1921; MacRoberts and MacRoberts, Ornithol. Monogr. 21, 1976). Under certain conditions holes or crevices of almost any size or shape may be sufficient to “release” storage behavior (Ritter, Scientific Monthly 31:253-257, 1930; Gignoux, Condor 23:118-121, 1972). This note reports acorn storage in pine cones. The location is particularly inappropriate because 1) the acorns are not retrievable, and 2) the storage site itself is of an impermanent and transitory nature.
