I developed two versions of the twin threshold model (TTM) to assess risk-sensitive foraging decisions by rufous hummingbirds. The model incorporates energy thresholds for both starvation and reproduction and assesses how three reward distributions with a common mean but different levels of variance interact with these critical thresholds to determine fitness. Fitness, a combination of survival and reproduction, is influenced by both the amount of variance in the distributions and the relative… Expand

Risk-sensitive foraging in rufous hummingbirds (Selasphorus Rufus) : a test of the twin-threshold model
TLDR
In the baseline trials hummingbirds subjected to the low-volume treatment preferred the nil variance, whereas those exposed to the high-volume Treatment preferred the moderate variance option, which is consistent with the twin-threshold model. Expand
Risk indifference in white-eared hummingbirds (Hylocharis leucotis) confronting multiple foraging options
TLDR
There was no influence of variance of nectar volume and sugar concentration on the choice behavior of the birds, ruling out the possibility that white-eared hummingbirds are risk sensitive under these conditions of 4 foraging alternatives, suggesting an effect of having multiple foraging options that had been ignored due to the design of previous risk experiments. Expand
Risk sensitivity revisited: from individuals to populations
TLDR
The results show that high baseline mortality does not necessarily lead to risk proneness and the model confirms the crucial importance of resource-independent (baseline) mortality for optimal risk-sensitive behaviour. Expand
Both the past and the present affect risk-sensitive decisions of foraging rufous hummingbirds
TLDR
It is suggested that the energetic conditions experienced by animals prior to testing had a significant impact on the animals' risk-sensitive decisions, and their memories of those prior conditions may have played an additional role. Expand
Social class influences degree of variance sensitivity in wild Siberian jays
TLDR
Training groups of wild Siberian jays to forage from one-shot feeders containing 3 color-coded options found variance-sensitive behavior under natural conditions but also demonstrated the presence of significant differences in variance sensitivity within groups, for the first time. Expand
Testosterone levels in feces predict risk-sensitive foraging in hummingbirds
TLDR
The role of steroid hormones testosterone (T) and corticosterone (CORT) on the foraging preferences expressed by white-eared hummingbirds Hylocharis leucotis is evaluated in a risk-sensitivity experiment. Expand
Risk-sensitive foraging and the evolution of cooperative breeding and reproductive skew
TLDR
The model clearly demonstrates that reproductive skew qualitatively changes the influence of food sharing on the reproductive output of groups and shows that the individual benefits of variance reduction in egalitarian groups and variance enhancement in groups with reproductive skew depend critically on ecological and life-history parameters.

Loyalty pays: potential life history consequences of fidelity to marine foraging regions by southern elephant seals
Choices made by foraging animals should maximize energy intake, although ‘irrational’ short-term behaviours are common. One explanation for this is that environmental variation may lead to theExpand
Caste-specific differences in risk sensitivity in honeybees, Apis mellifera
TLDR
This work compared risk sensitivity of workers and drones and their ability to discriminate between the reward volumes used in the risk sensitivity experiments, and found that workers showed greater risk aversion than drones, the first demonstration of caste-specific differences in risk sensitivity. Expand
Foraging on variable resources : the behaviour and decision making of rufous hummingbirds
TLDR
Investigating influences on foraging decisions at a large scale (population density) and small scale (resource variability) has provided a much wider understanding of their foraging behaviour than either could alone. Expand

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. Expand
A model of risk-sensitive foraging for a reproducing animal
TLDR
The policy that maximizes expected lifetime reproductive success was found and the pattern of risk-sensitive behaviour predicted was compared with that predicted by a similar model in which no reproduction occurs and the optimality criterion is to minimize the probability of death. Expand
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 beExpand
Hummingbird Foraging at Experimental Patches of Flowers: Evidence for Weak Risk-Aversion
TLDR
Lack of a stronger response to reward variance may derive from the fact that hummingbirds sample thousands of flowers a day, so that the total profit realized over a day is not strongly influenced by flower-to-flower variation. Expand
Risk-Sensitive Foraging, Fitness, and Life Histories: Where Does Reproduction Fit into the Big Picture?
TLDR
It is suggested that risk-prone foraging may be likely when factors other than survival are important for fitness, and using a mix of modelling techniques and stochastic dynamic programming is recommended. Expand

TLDR
While the small sample sizes reduced the power to detect treatment effects, the results seem robust in that no jay under any treatment exhibited a preference for the low variance patch, and the development of side biases was a problem in this study as it was in Ha et at. Expand
Risky Theories—The Effects of Variance on Foraging Decisions
TLDR
It is found that when risk is generated by variability in the amount of reward, animals are most frequently risk-averse and sometimes indifferent to risk, although in some studies preference depends on energy budget. Expand

TLDR
It will be argued that to understand the foraging decisions of animals account needs to be taken of both the psychological mechanisms underlying decision-making and the fitness consequences of different decisions for the forager. Expand
Risk‐Sensitive Foraging Strategies of Two Spider Populations
TLDR
It was found that foraging mode differed between habitats in the long-jawed orb-weaving spider Tetragnatha elongata, and a subsequent field experiment indicated that the risk-sensitive model adequately predicted observed variation in foraging behavior. Expand
Rick-sensitive foraging in common shrews: an interruption model and the effects of mean and variance in reward rate
TLDR
A model of risk-sensitive foraging based on a continuously foraging but interruptable predator is developed and tested in a simple choice experiment using common shrews and preference was influenced most clearly by experience of reward rate variance during tests rather than training. Expand
