Interacting cache memories: Evidence for flexible memory use by Western scrub-jays (Aphelocoma californica).
Abstract
When Western Scrub-Jays (Aphelocoma californica) cached and recovered perishable crickets, N. S. Clayton, K. S. Yu, and A. Dickinson (2001) reported that the jays rapidly learned to search for fresh crickets after a 1-day retention interval (RI) between caching and recovery but to avoid searching for perished crickets after a 4-day RI. In the present experiments, the jays generalized their search preference for crickets to intermediate RIs and used novel information about the rate of decay of crickets presented during the RI to reverse these search preferences at recovery. The authors interpret this reversal as evidence that the birds can integrate information about the caching episode with new information presented during the RI.

Scrub-jays are able to integrate novel semantic information acquired after the event with the what-where-when event information, allowing for cognitive flexibility.
“and are able to integrate novel semantic information (acquired after the event) with the what–where–when event information, allowing for cognitive flexibility [60].”

Scrub-jays integrate novel semantic information with an original episodic-like memory of a caching event, and acquired this information after the event.
“Scrub-jays were observed to integrate novel semantic information with an original episodic-like memory of a caching event, and importantly, acquired this information after said event [60].”

Much of the evidence for episodic-like memory in birds, particularly using the what-where-when paradigm, has revolved around food caching in species highly specialized in this behaviour: scrub-jays, Eurasian jays, magpies, and black-capped chickadees.
“Much of the evidence for episodic-like memory in birds, particularly using the what–where–when paradigm, has revolved around food caching in species that are highly specialized in this behaviour, namely scrub-jays [52,59,60], Eurasian jays [92], magpies [61] and black-capped chickadees [62].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
