“…The lack of an effect could imply that our treatment did not influence the birds’ perceived predation risk. However, earlier work provided evidence that it did: the predator treatment affected great tit behaviour and mass (Abbey‐Lee, Kaiser, et al., ; Abbey‐Lee, Mathot, et al., ; Mathot, Abbey‐Lee, & Dingemanse, ), suggesting that the lack of an effect on extra‐pair paternity is a true null result not a result of flaws in the experimental design.…”

“…The sparrowhawk is the main avian predator of great tits (Geer, ; Perrins & Geer, ), and sparrowhawk predation is known to select for increased fledgling mass in this species (Vedder, Bouwhuis, & Sheldon, ). Previously, we demonstrated that individuals perceived our manipulation as increasing predation risk: territorial breeders vocalized less and increased the proportion of alarm calls vs. songs (Abbey‐Lee, Kaiser, Mouchet, & Dingemanse, ). Moreover, in winter, fast explorers responded more strongly to the manipulation by decreasing their body mass, implying phenotype‐specific responses (Abbey‐Lee, Mathot, et al., ).…”

“…9–12 ha. We conducted a playback experiment to manipulate perceived predation risk, with a design detailed extensively elsewhere (Abbey‐Lee, Kaiser, et al., ; Abbey‐Lee, Mathot, et al., ). Four speakers (Shockwave, Foxpro, Pennsylvania, USA) were placed in each plot in March.…”

“…The amount of silence between playbacks was determined randomly to avoid habituation. Speakers broadcast from March through July following a 4 day on (speakers were actively broadcasting)‐ 4 day off (no playback) scheme, a design that prevents habituation and has been demonstrated to influence anti‐predator response even after predator cues cease (Abbey‐Lee, Kaiser, et al., ; Zanette et al., ). Such carry‐over effects (specifically, altered singing behaviour up to 4 days post‐predator playback, Abbey‐Lee, Kaiser, et al., ) indicate that sparrowhawk playbacks alter perception of risk over longer time periods – justifying the use of sparrowhawk playback for manipulating general predation risk levels during the breeding season.…”

Non‐consumptive predator effects have been shown to influence a wide range of behavioural, life history and morphological traits. Extra‐pair reproduction is widespread among socially monogamous birds and may incur predation costs. Consequently, altered rates of extra‐pair reproduction are expected in circumstances characterized by increased adult perceived predation risk. In addition, extra‐pair reproduction is expected to be most affected for birds with phenotypes that generally increase predation risk (such as more active individuals). In two consecutive years, perceived predation risk was manipulated for great tits Parus major breeding in 12 nest‐box plots by broadcasting sounds of their main predator (European sparrowhawk Accipiter nisus; six plots). As a control treatment, sounds of a sympatric, avian non‐predator species were broadcast (Eurasian blackbird Turdus merula; six plots). Levels of extra‐pair paternity did not differ between plots with different predation risk treatments. Males that moved more in a novel environment (more active or “faster exploring”) tended to have offspring with fewer partners, but this effect did not vary with predation risk treatment. From an adaptive viewpoint, predation costs associated with extra‐pair reproduction may be small and may not outweigh the benefits of extra‐pair behaviour. Research on a broader range of taxa with different mating strategies is now needed to confirm the generality of our findings.

“…We therefore conclude that phenotypic adjustments to day-to-day variation in human disturbance might well differ between behavioral traits, perhaps because the costs or limits associated with phenotypic plasticity are trait-specific (DeWitt et al, 1998;Auld et al, 2010). Our recent studies on aggressiveness, for example, demonstrated that this particular behavior (which birds did not plastically adjust to changes in human disturbance; Table 1) is also not plastically adjusted to population density (Araya-Ajoy and Dingemanse, 2017) or perceived predation risk (Abbey-Lee et al, 2016). Overall, the lack of evidence for within-individual plasticity suggests that its role in urban ecology may be more modest than previously anticipated (Lowry et al, 2013).…”

The impact of urbanization has been widely studied in the context of species diversity and life history evolution. Behavioral adaptation, by contrast, remains poorly understood because empirical studies rarely investigate the relative importance of two key mechanisms: plastic responses vs. non-random distributions of behavioral types. We propose here an approach that enables the simultaneous estimation of the respective roles of these distinct mechanisms. We investigated why risky behaviors are often associated with urbanization, using an urban nest box population of great tits (Parus major) as a study system. We simultaneously and repeatedly quantified individual behavior (aggression and flight initiation distance) as well as environmental factors characterizing level of urbanization (numbers of pedestrians, cars and cyclists). This enabled us to statistically distinguish plastic responses from patterns of non-random distributions of behavioral types. Data analyses revealed that individuals did not plastically adjust their behavior to the level of urbanization. Behavioral types were instead non-randomly distributed: bold birds occurred more frequently in areas with more cars and fewer pedestrians while shy individuals were predominantly found in areas with fewer cars and more pedestrians. These novel findings imply a major role for behavioral types in the evolutionary ecology of urban environments and call for the full integration of among-and within-individual variation in urban ecological studies.

Vocalization is an important communication tool that can reflect many aspects of an individual's internal and external condition. This is especially true for birds. Previous research has shown that bird calls and songs change in response to a variety of potential stressors, although the extent and direction of the changes depend on the nature of the stressor and the environment. Circulating glucocorticoids, such as corticosterone, often increase in response to stressors and mediate some of the observed changes via alterations of the individual's physiological state. Acute elevations of corticosterone often occur as a physiological response to short‐term stressors; however, the effects of this elevation on adult vocalizations have not been well documented. Here, we experimentally elevated corticosterone at two different levels using a noninvasive method and examined the effects on the vocal communication of male and female adult common mynas (Acridotheres tristis). Corticosterone elevation temporarily increased song output and some measures of song complexity, while call output decreased. These effects were dosage dependent (higher corticosterone levels had a stronger effect), most evident 40 min after ingestion, and some vocal changes were sex‐specific. Future studies should investigate whether the changes in vocal performance due to elevated glucocorticoids have consequences for the birds' behavior, reproductive success, and survival.
