TLDR
It is suggested that the perishability of seeds exerts a greater influence than handling time on the grey squirrel's decision to cache acorns, and predicts the predictions for caching behaviour that follow from these two hypotheses.About:

Episodic-like memory during cache recovery by scrub jays
TL;DR: It is shown that scrub jays remember ‘when’ food items are stored by allowing them to recover perishable ‘wax worms’ (wax-moth larvae) and non-perishable peanuts which they had previously cached in visuospatially distinct sites.

TL;DR: By synthesising knowledge of how the environment affects seeds to determine when and how they leave the soil seed bank into a resistance–exposure model, this work provides a new framework for developing experimental and modelling approaches to predict how long seeds will persist in a range of environments.

How plants manipulate the scatter-hoarding behaviour of seed-dispersing animals
TL;DR: Some plants that are dispersed by scatter-hoarding animals appear to have evolved the ability to manipulate the behaviour of those animals to increase the likelihood that seeds and nuts will be stored and that a portion of those items will not be recovered.

Scrub jays (Aphelocoma coerulescens) remember the relative time of caching as well as the location and content of their caches.
TL;DR: Two experiments examined whether food-storing scrub jays (Aphelocoma coerulescens) could remember the relative time of caching as well as what type of food was cached in each cache site.

Scrub jays (Aphelocoma coerulescens) form integrated memories of the multiple features of caching episodes.
TL;DR: It is argued that the jays formed an integrated memory for the location and time of caching of particular foods in visuospatially distinct and trial-unique caches.
