AbstractWe allowed seven willow tits, Parus montanus, to store and retrieve with retention intervals of 1, 7, 21 and 56 days, in four experimental rooms. Retrieval success decreased over time, indicating a decaying memory for cache locations. Compared to what could be expected by chance, retrieval success was better after all retention intervals. Our results suggest that - after the longer retention intervals - this might depend on preferences for certain types of caching locations rather than memory. If both general and individual preferences are controlled for, birds retrieved significantly better than expected one and seven days after storing, but not later than that.

Cache Recovery

This field study examined experimentally whether Northwestern Crows (Corvus caurinus) used random search or memory to relocate food caches. The crows cached food items in the ground, one per cache, and covered the cache before leaving the site. Most caches were recovered within 24 h. The crows found caches made by me 1 m from their own caches significantly less often than they found their own caches. Replacing the covering of the cache with material other than the crows used did not significantly affect recovery success, but the crows found significantly fewer of their caches when the latter were experimentally moved 15 cm. Adding a 25 cm long stick to the site 15 cm from the cache significantly decreased a crow's ability to relocate its cache, but not when it was placed 30 cm away. A 50 cm long stick placed 15 or 30 cm away had the same negative effect on a crow's ability to relocate its cache, but not when it was placed 45 cm away. When memory is used, recovery success can be as high as 99%; when random search is used, it can be as low as 6%.
