An experimental study of clam storage by a Northwestern Crow (Corvus caurinus) was carried out on Mitlenatch Island, British Columbia, Canada. The crow was trained to take clams from a feeding table. His dispersion of the clams was studied using nearest-neighbour distance (NND). The distance clams were carried and the sequence of storage and recovery was also quantified. Median NND was significantly correlated with storage sequence position, as was NND with distance carried. The crow tended to recover the clams in the same order as he stored them, as storage sequence position was significantly correlated with recovery sequence position. The results were compared with other spatiotemporal studies of avian food hoarding. Recovery success of the crow was very high, he appeared to use memory to relocate his caches, as the majority of them were made in new sites, and he never revisited those already emptied.
