Many animals use spatial memory. Although much work has examined the accuracy of spatial memory, few studies have explicitly focused on its longevity. The importance of long-term spatial memory for foraging has been demonstrated in several cases. However, the importance of such long-term memory for all animals is unclear. In this study, we present the first evidence that a parid species (the black-capped chickadee, Poecile atricapillus) can remember the location of a single food item for at… 
Interaction of memory systems is controlled by context in both food-storing and non-storing birds
Context was a powerful factor controlling the interaction of memory systems in both black-capped chickadees and dark-eyed juncos and no species differences in the weighting of habit and one-trial memory were found.
Spatial Memory in Food-Hoarding Animals
Cognitive Ecology of Food Hoarding: The Evolution of Spatial Memory and the Hippocampus
It is concluded that existing evidence strongly supports the hypothesis that spatial memory and its underlying neural mechanisms respond to selection pressures associated with scattness as a function of differences in the environment.
Long-term memory of hierarchical relationships in free-living greylag geese
Investigation of long-term memory of hierarchically ordered relationships, where the position of a reward depended on the relationship of a stimulus relative to other stimuli in the hierarchy indicates that geese may remember dyadic relationships for at least 6 months and probably well over 1 year.
Potential Mechanisms Driving Population Variation in Spatial Memory and the Hippocampus in Food-caching Chickadees.
The existing data are most consistent with the hypothesis that highly predictable differences in winter climate drive the evolution and maintenance of differences among populations both in cognition and in the brain via local adaptations, at least in food-caching parids.
Flexible use of memory by food-caching birds
This work studied spatial behaviors of the chickadee, a food-caching bird, and found that chickadees use some navigational strategies that are independent of cache memories, including opportunistic foraging and spatial biases.


Long-term memory for a life on the move

It is shown that memory of a particular feeding site persisted for at least 12 months in a long-distance migrant, whereas a closely related nonmigrant could remember such a site for only 2 weeks, suggesting that the migratory lifestyle has influenced the learning and memorizing capacities of migratory birds.
Evidence for large long-term memory capacities in baboons and pigeons and its implications for learning and the evolution of cognition

It is demonstrated that pigeons and monkeys have sufficient memory resources to develop memory-based exemplar or feature learning strategies in many test situations and suggests that the evolution of cognition and behavior importantly may have involved the gradual enlargement of the long-term memory capacities of the brain.

The present findings suggest conservation of long-term memory mechanisms and effectiveness in humans relative to nonhuman primates, despite at least 20 million years of divergent evolution and vastly different behavioral and cognitive repertoires.
Remarkable spatial memory in a migratory cardinalfish
The results suggest that female A. notatus have long-distance homing ability to pinpoint the exact location of their previous territory, and retain spatial memory for as long as 6 months.
A test of the adaptive specialization hypothesis: population differences in caching, memory, and the hippocampus in black-capped chickadees (Poecile atricapilla).
The results support the hypothesis that population differences in food caching, memory, and the hippocampus of black-capped chickadees from Alaska and Colorado reflect adaptations to a harsh environment.
Memory for locations of stored food in willow tits and marsh tits
This experiment tested the hypothesis that retrieval success (and thus memory capacity) of the two species differs depending on the usual length of time for which food is stored, and found that both species successfully retrieved food after both delays.
Variation in memory and the hippocampus across populations from different climates: a common garden approach
It is found that differences in hippocampal neuron number, neurogenesis and spatial memory previously observed in wild chickadees persisted in hand-raised birds from the same populations, even when birds were raised in an identical environment, rejecting the hypothesis that variation in these traits is owing solely to differences in memory-based experiences in different environments.
Stress and glucocorticoids impair retrieval of long-term spatial memory
It is shown that rats have impaired performance in a water-maze spatial task after being given footshock 30 min before retention testing but are not impaired when footshock is given 2’min or 4 h before testing, which suggests that the retention impairment is directly related to increased adrenocortical function.
Mechanisms of cache retrieval in long-term hoarding birds
It is suggested that differences between the families in their degree of dependence on stored food or/and size-related limitations of brain capacity may be important.
