“…Calling in this latter case would therefore likely be riskier, resulting in an increased time of silence following the acoustic predation cue. These results support previous studies [77][78][79] that found if a predator stimulus is visual as opposed to acoustic, then foraging rates in those prey species are reduced and anti-predatory behavior (vigilance, calling) is increased. Interestingly, with the exception of chickadee calling latency being predicted by conspecific number, our results are not mirrored between the studies.…”

Carolina chickadees (Poecile carolinensis) and tufted titmice (Baeolophus bicolor) regularly form flocks with multiple species through the winter months, including white-breasted nuthatches (Sitta carolinensis). Earlier studies found that behavior of both chickadees and titmice was sensitive to mixed-species flock composition. Little is known about the influence of background noise level and vegetation density on the antipredator behaviors of individuals within these flocks, however. We tested for the effects of vegetation density, traffic noise, and flock composition (conspecific number, flock diversity, and flock size) on antipredator behavioral responses following an alarm call playback (Study 1) and an owl model presentation (Study 2) at feeders. We recorded background traffic noise and performed lidar scans to quantify vegetation density at each site. After a feeder had been stocked with seed and a flock was present, we recorded calls produced, and we identified flock composition metrics. We coded seed-taking latency, call latency, mob latency, and mob duration following the respective stimulus presentation and tested for effects of flock composition metrics, vegetation density, and background noise on these responses. For the alarm call playback study, flock composition drove behaviors in chickadees and titmice, and vegetation density drove behaviors in chickadees and nuthatches. For the owl model study, conspecific number predicted behavior in chickadees, and mob duration was predicted by nuthatch number. The results reveal individual sensitivity to group composition in anti-predatory and foraging behavior in simulated risky contexts. Additionally, our data suggest that the modality of perceived simulated risk (acoustic vs. visual) and the density of vegetation influence behavior in these groups.

The biological significance of behavioural predictability (environment-independent within-individual behavioural variation) became accepted recently as an important part of an individual's behavioural strategy besides behavioural type (individual mean behaviour). However, we do not know how behavioural type and predictability evolve. Here, we tested different evolutionary scenarios: (i) the two traits evolve independently (lack of correlations) and (ii) the two traits' evolution is constrained (abundant correlations) due to either (ii/a) proximate constraints (direction of correlations is similar) or (ii/b) local adaptations (direction of correlations is variable). We applied a set of phylogenetic meta-analyses based on 93 effect sizes across 44 vertebrate and invertebrate species, focusing on activity and risk-taking. The general correlation between behavioural type and predictability did not differ from zero. Effect sizes for correlations showed considerable heterogeneity, with both negative and positive correlations occurring. The overall absolute (unsigned) effect size was high (Zr = 0.58), and significantly exceeded the null expectation based on randomized data. Our results support the adaptive scenario: correlations between behavioural type and predictability are abundant in nature, but their direction is variable. We suggest that the evolution of these behavioural components might be constrained in a system-specific way.

“…Each feeder was located in a grassy area, approximately 5 m from the nearest forest edge. The Arboretum feeder was placed within the GVSU VanSteeland Arboretum while the AuSable feeder was approximately 12 m from a little-used exit door of GVSU's AuSable Hall (Figure S1 in the online supplemental materials); the locations were selected to be as similar as possible while still remaining close enough ( 130 m apart) so that the same birds would visit both (Mathot et al, 2022). Both sites experienced minimal human disturbance during our trials.…”

Black-capped chickadees (Poecile atricapillus) and other species that feed at bird feeders balance the benefit of easy foraging with the added risk of predation. Individual birds respond differently to risky situations, and these differences have been attributed to the birds' personalities, which researchers commonly assess with an "open-field" behavioral assay. However, these behavioral assays in birds have not been compared to behavior in the wild in the context of foraging in the presence of a predator (i.e., risk-taking behavior). We colorbanded chickadees in a wild population and conducted behavioral assays in the field. We later used foraging trials to investigate these color-banded individuals' responses to a predator (Cooper's hawk, Accipiter cooperii) model or a series of Cooper's hawk calls. We found that foraging black-capped chickadees responded more strongly to the presence of a predator model than to predator calls. Individual birds differed in their responses, and the behavioral assays (activity and exploration) predicted individual behavior in the wild during the foraging experiments. Activity and exploration assay scores were only weakly related, suggesting these two assays represent different traits. Both highly active birds and fast explorers exhibited some reluctance to visit the feeder (either reduced number of visits or greater latency to visit) when the predator model was present, a relationship that was somewhat unexpected. Our results suggest that standard behavioral assays predict behavior in the wild, but care should be taken when generalizing among species and studies.
