Visual Detection of Cryptic Prey by Blue Jays (Cyanocitta cristata).
Blue jays learned to respond differentially to the presence or absence of Catocala moths in slides. This detection of the moths by the jays was affected by the background upon which the moth was placed and its body orientation, thus providing an objective measure of crypticity. These procedures are useful for the study of visual detection of prey.
متن کاملBlue jays, Cyanocitta cristata, devalue social information in uncertain environments
http://dx.doi.org/10.1016/j.anbehav.2015.11.015 0003-3472/© 2015 The Association for the Study of A Animals are selective about when to learn by observing others. Models predict that social information becomes less reliable in uncertain environments, and therefore animals should reduce their use of social information in these environments; however, these parameters are often difficult to manipu...
متن کاملHabitat and Nesting Success of Blue Jays (cyanocitta Cristata): Importance of Scale
—Nesting success of birds often is influenced by habitat features surrounding nests. However, few studies have investigated habitat influences at multiple levels and spatial scales. We examined the relationship between Blue Jay (Cyanocitta cristata) nesting success and habitat at three levels (macrohabitat, microhabitat, and nest site) and at three different scales within the microhabitat level...
متن کاملVisual search and attention in blue jays (Cyanocitta cristata): Associative cuing and sequential priming.
Visual search for complex natural targets requires focal attention, either cued by predictive stimulus associations or primed by a representation of the most recently detected target. Because both processes can focus visual attention, cuing and priming were compared in an operant search task to evaluate their relative impacts on performance and to determine the nature of their interaction in co...
متن کاملThe effects of prey depletion on the patch choice of foraging blue jays (Cyanocitta cristata)
Blue jays (Cyanocitta cristata) were trained to hunt for non-cryptic moths presented in projected images. On each trial, the jays chose one of two patches to hunt in: (1) a uniform, “non-depleting” patch with constant prey density of 0.25; or (2) a “depleting” patch in which prey density changed during the foraging bout. In the depleting patch, the initial prey density was 0.50, declining to ze...
