We tested the risk-sensitive foraging preferences of wild rufous hummingbirds, Selasphorus rufus, with three types of artificial flowers. All three flower types provided the same mean volume of 30 µl of sucrose, but differed in terms of variability of the reward: constant, low variance and high variance. In trinary comparisons, subjects preferred the low-variance reward over the constant reward, and the constant reward over the high-variance reward; a result not predicted by risk-sensitive… 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
The twin threshold model: risk-intermediate foraging by rufous hummingbirds, Selasphorus rufus
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 andExpand
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
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
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
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. 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.

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
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
The value of information to foraging Calliope Hummingbirds
TLDR
The results indicate that when all things are equal, calliope hummingbirds prefer to forage where most information is available about resource quality. Expand

A TEST OF RISK-SENSITIVE FORAGING IN WILD BUMBLE BEES'
TLDR
Wild-foraging bumble bees appear to be sensitive to both the mean and the variance of the energy rewards offered by alternative flower species, and this sensitivity is affected by colony energy requirements. Expand
A Field Test of Risk-Sensitive Foraging in Black-Capped Chickadees (Parus Atricapillus)
TLDR
The first field test of a risk-sensitive foraging model was conducted on Black-capped Chickadees, showing a clear, significant preference for the lower variance prey and suggesting the importance of the incorporation of environmental stochasticity into models of animal foraging. 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
Optimal foraging in hummingbirds : testing the marginal value theorem
TLDR
The hypothesis is that hummingbirds will adopt the decision rule that maximizes their net rate of energy gain while foraging, which leads to an analogue of Charnov's marginal value theorem which determines an optimal decision rule. Expand

The Logic of Risk-Sensitive Foraging Preferences It has recently been shown that the foraging preferences of animals are sensitive to variance in the probability distribution of a food reward (CaracoExpand
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
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

TLDR
Comparisons of feeding territories of S. rufus and other nectarivorous birds indicate similarities which suggest that these systems may be subject to similar economic constraints. Expand
CONTRASTING VIEWS OF HUMMINGBIRD VISITS TO FLOWERS
TLDR
The conclusion that energy intake rate and optimal nectar concentration are sensitive to temporal scale of integration applies at all scales in hummingbird foraging systems, and it is suggested that it also generalizes across systems. Expand
