Abstract. Numerous previous investigators have explained species differences in spatial memory performance in terms of differences in foraging ecology. In three experiments we attempted to extend these findings by examining the extent to which the spatial memory performance of echidnas (or "spiny anteaters") can be understood in terms of the spatio-temporal distribution of their prey (ants and termites). This is a species and a foraging situation that have not been examined in this way before… Expand
Win-shift and win-stay learning in the rainbow lorikeet (Trichoglossus haematodus).
The first attempt to test for a win-shift bias in a nectarivorous parrot, the rainbow lorikeet (Trichoglossus hematodus), is reported, suggesting that an innate tendency to win- shift may not be present in all avian ninatorivores, or that the role experience plays in shaping such behaviors is different for different species.

Win shifting in nectarivorous birds: selective inhibition of the learned win-stay response
A variety of nectarivorous species have demonstrated a bias to ‘win-shift’ (shift away from/avoid locations that have recently yielded food, as opposed to ‘win-stay’ behaviour where the animalExpand
Food-specific spatial memory biases in an omnivorous bird
It is found that the win–shift bias was sensitive to foraging context, manifesting only in association with foraging for nectar, not with foraged for invertebrates. Expand
How Memory-Based Movement Leads to Nonterritorial Spatial Segregation
A spatially explicit mechanistic movement model was built to investigate how simple memory-based foraging rules may enable animals to establish HRs and to what extent this increases their foraging efficiency compared to individuals that do not base foraging decisions on memory. Expand
A Spatial memory task in the rainbow trout (Oncorhynchus mykiss)
The experiment suggests that rainbow trout engage in ‘win stay’ behaviour, which may help to understand the spatial memory regarding win-stay in rainbow trout. Expand
Conditional same/different concept learning in the short-beaked echidna (Tachyglossus aculeatus).
It is demonstrated that echidnas are able to discriminate on the basis of a relational same/different concept, using simultaneously presented multi-element stimuli, and transfer that discrimination to novel stimuli. Expand
Chemical communication for reproduction in the Tasmanian short-beaked echidna, Tachyglossus aculeatussetosus
The results suggest that females do not ‘actively’ signal to males while hibernating, but intense male-male competition for access to females has probably driven earlier male readiness to breed, even before females might otherwise emerge from hibernation and signal toMale echidnas. Expand
Habitat use over winter by short-beaked echidnas (Tachyglossus aculeatus) at an intermittently flowing creek in arid north-western New South Wales
Investigating echidna home ranges and the importance of food and shelter availability in habitat selection over one winter concluded that habitat selection patterns were driven by prey availability (ants) and shelter (leaf litter). Expand
Is predation a driver of polydomy in ants
The frequency of polydomy in a population increases when a predator would destroy the entire nest, but that the addition of defence by retaliation has no effect on the frequency ofpolydomy, which suggests that polydomous colonies do benefit from dilution of risk, but not from improved retaliation.

Retention period differentially attenuates win–shift/lose–stay relative to win–stay/lose–shift performance in the rat

Hungry rats were trained in a two-lever conditioning chamber to earn food reinforcement according to either a win–shift/lose–stay or a win-stay/losing–shift contingency, and the lose–stay rule was differentially negatively impacted relative to the other rules. Expand


Spatial memory in rufous hummingbirds: memory for rewarded and non-rewarded sites
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
Spatial memory in rufous hummingbirds (Selasphorus rufus): A field test
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
The Role of Exploration in Win-Shift and Win-Stay Performance on a Radial Maze.
Abstract Win-shift spatial memory tasks in a radial maze reinforce animals for avoiding previously visited rewarded arms; win-stay tasks reinforce them for returning to those arms. Win-shift tasksExpand
Ovenbird (Aves: Parulidae) hunting behavior in a patchy environment: an experimental study
Since less search path was required per prey found in denser patches, the search effort was concentrated in areas of high profitability and the birds took a higher percentage of prey available in these patches. Expand
Patch use and prey defence in a mammalian myrmecophage, the echidna (Tachyglossus aculeatus) (Monotremata: Tachyglossidae): a test of foraging efficiency in captive and free-ranging animals
It is suggested that echidnas make efficient use of patchily distributed prey and generally adjust their foraging efforts to match actual energetic returns. Expand
The Food Searching Behaviour of Two European Thrushes. Ii: the Adaptiveness of the Search Patterns
Although there were suggestions of differing capture rates, unforeseen errors in experimental procedure did not allow firm conclusions on the effects of thrush predation on the different prey distributions within each density, it is suggested that the increases in move lengths were an adaptive reaction by the blackbirds to increases in prey detectability.

The Food Searching Behaviour of Two European Thrushes
1. The movement path of a predator will clearly be an important determinant of its ability to encounter and subsequently attack suitable prey items. Previous work on this aspect of searchingExpand
A comparison of four corvid species in a working and reference memory task using a radial maze.
Results are consistent with phylogenetic relationships among the 4 species, but could also be explained by differences in response strategies or interference in processing both types of memory components of the maze. Expand
Performance of four seed-caching corvid species in operant tests of nonspatial and spatial memory.
The performance of 4 seed-caching corvid species was tested using 2 different operant nonmatching tasks, and species differences in the spatial task were found for acquisition and during retention testing. Expand
In general, sunbirds feeding at Leonotis responded less to reward levels by differential turning and movement than some other organisms, possibly reflecting different prey distributions or boundary constraints on their foraging. Expand
