It is conventionally assumed that, when animals evaluate alternative options, the value assigned to an option is absolute and independent of the other options available. It follows that animal choices should exhibit the rational property of regularity whereby the proportion of choices for an option cannot be increased by the addition of further options to the choice set. However, violations of regularity occur in human decision making, suggesting that humans may use comparative evaluation…

Context–dependent foraging decisions in rufous hummingbirds
TLDR
M measuring the foraging preferences of rufous hummingbirds faced with choices analogous to those in which human use of relative currencies is evident finds results similar to those reported in the human choice literature, and are compatible with the hummingbirds using a relative evaluation mechanism in decision making.
Individual differences in decision making by foraging hummingbirds
Context-dependent decision making in wild rufous hummingbirds
TLDR
Human and hummingbirds make irrational choices as the decision making context can change the choices that they make, according to conventional models of decision making.
Context-dependent foraging choices in risk-sensitive starlings
Existing models of risk-sensitive foraging assume that animals assign value to different options according to an absolute currency. It follows from this assumption that choices are expected to be
Rationality in risk-sensitive foraging choices by starlings
TLDR
This work investigates rationality in risky choice using European starlings, Sturnus vulgaris, and suggests that violations of rationality in risk-sensitive choices may be expressed only under restricted sets of conditions.
The starling as a rational decision maker
A central question in behavioural and evolutionary ecology is to understand how animals make decisions between, for instance, potential mates, nesting sites, foraging patches and territories.
Irrational choice and the value of information
TLDR
This study illustrates how experimentally induced irrational behaviour supports rather than weakens the evolutionary optimality approach to animal behaviour.
Phantom alternatives influence food preferences in the eastern honeybee Apis cerana.
TLDR
The effects of unattractive and attractive phantom alternatives on feeder preferences in the eastern honeybee are investigated, finding that the presence of an attractive food source, even if it is unavailable, can influence preference relationships between remaining items in the choice set.
Rationality in decision-making in the fringe-lipped bat, Trachops cirrhosus
TLDR
It is found that, unlike many other animals, the fringe-lipped bats appear to make consistent decisions, even with more complex choice sets, and these results counter many other experiments suggesting irrationality in animal decision-making.
Context-dependent mate choice in relation to social composition in green swordtails Xiphophorus helleri
TLDR
Although mate choice was context dependent, the asymmetrically dominated decoy effect was not observed, and females showed negative frequency-dependent preference for the rare-male phenotype, which may act to maintain genetic variation under sexual selection.

TLDR
A model of context-dependent choice is used to explore conditions under which adaptive choice based on a complex decision process can lead to intransitivity, and finds that in the experiment, the subjective value of option a was apparently lower in option set{a,c} than in {a,b}.

Context-dependent, risk-sensitive foraging preferences in wild rufous hummingbirds
TLDR
When tested with traditional binary comparisons, hummingbirds showed conventional risk-averse behaviour and selected the constant reward over the low- or high-variance rewards, a reversal of preference that represents a context-dependent foraging preference.
Background context and decision making in hoarding gray jays
TLDR
Food-hoarding gray jays showed a stronger preference for x than did subjects initially exposed to context, which implies that the jays did not assign a fixed value to each option, in violation of the principle of irrelevant alternatives.

TLDR
Neither hummingbirds' preferences nor the energetics of nectar extraction in this low-volume presentation account for the low nectar sugar concentrations characteristic of the flowers they pollinate.

TLDR
Stages in the choice process at which specific components of male courtship display influence female decisions were investigated using field observations of female pre-mating behavior, suggesting that attraction and active choice may impose conflicting selection pressures on display performance.
Importance of Energy Costs in Central Place Foraging by Hummingbirds
TLDR
Predictions from three models of central place foraging (CPF) in two field experiments with Calliope Hummingbirds showed that males increased meal size with travel distance from their perches to feeders, and took larger, heavier meals from fast-weak than from slow-rich feeder, but not the rate maximization model.
