Field experiments on squirrel spatial memory under naturalistic conditions showed that grey squirrels, Sciurus carolinensisare capable of relocating precise spatial goals using short range visual cues. These goals were in the form of buried food, similar to natural cache sites, and were relocated to within 5 cm in 62.5% of all attempts after a retention interval of 20 days. Some recall could be demonstrated after more protracted retention intervals (43 and 62 days). These results suggest that… Expand
Spatial Orientation on a Vertical Maze in Free-Ranging Fox Squirrels (Sciurus niger)
To determine how squirrels return to remembered locations in an arboreal environment, wild fox squirrels (Sciurus niger) were trained on an outdoor vertical maze. Squirrels were trained on 1 routeExpand
Spatial Memory in Food-Hoarding Animals
Abstract Many scatter-hoarding animals use spatial memory to relocate their stored food. In many cases, this spatial memory is of large capacity, with long duration and high resistance toExpand
Flexibility of cue use in the fox squirrel (Sciurus niger)
TLDR
The results of this study suggest that the study of free-ranging animals over a variety of conditions is necessary for understanding spatial cognition. Expand
Spatial accuracy in food-storing and nonstoring birds
TLDR
It is concluded that the accuracy of spatial memory in food-storing birds is greater than that of nonstorers. Expand
Remarkable spatial memory in a migratory cardinalfish
TLDR
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. Expand
Title Remarkable spatial memory in a migratory cardinalfish.
TLDR
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. Expand
Sex and species differences in spatial memory in food-storing kangaroo rats
TLDR
Spatial ecology predicted both species and sex differences in spatial memory in kangaroo rats that are predicted by foraging ecology and found a significant interaction between the presence of local landmarks and sex on target recovery. Expand
Learning is negatively associated with strength of left/right paw preference in wild grey squirrels (Sciurus carolinensis)
TLDR
An empirical test examining the relationship between lateralization and cognitive performance in wild grey squirrels found a negative relationship between strength of paw preference and performance on the learning task, suggesting a mammal/non-mammal divide in this relationship. Expand
Memory in Food Caching Animals
Many scatter-hoarding animals use spatial memory to relocate their stored food. In many cases, this spatial memory is of large capacity, with long duration and high resistance to interference.Expand
Placement, Retrieval, and Memory of Caches by Thirteen-Lined Ground Squirrels
TLDR
The results imply that 13-lined ground squirrels rely heavily on spatial memory for retrieval and are the first experimental demonstration of the importance of memory for cache recovery in a natural population of mammals. Expand

The spatial memory abilities of free-ranging rufous hummingbirds were tested in an “open-field” analogue of a radial maze. Eight artificial “flowers” filled with sucrose solution and arranged in aExpand
How marsh tits find their hoards: the roles of site preference and spatial memory.
TLDR
Marsh tits (Parus palustris) store single food items in scattered locations and recover them hours or days later, and during recovery they are more likely to visit a site of any preference value if they have stored a seed there that day than if they had not. Expand
Memory for the location of stored food in marsh tits
TLDR
It seems likely that recovery of stored food by marsh tits and other birds occurs by memory of storage sites, not by chance encounter during foraging. Expand

Spatial memory in rufous hummingbirds: memory for rewarded and non-rewarded sites
TLDR
The foraging ecology of rufous hummingbirds, Selasphorus rufus, suggests that this species may have good spatial memory capabilities, and information about rewarded and non-rewarded locations was combined to direct sampling behaviour towards flowers the birds had not yet encountered. Expand

Abstract It has previously been assumed that grey squirrels, Sciurus carolinensis , cannot remember the locations of nuts they have buried, and hence must relocate nuts by their odour. ThisExpand
Spatial memory in food-storing birds
TLDR
In the wild, several species of birds among the parids (tits and chickadees) and corvids store food in scattered locations and find it again days or months later, suggesting that they possess an adaptive specialization of some aspect or aspects of memory. Expand
