Background context and decision making in hoarding gray jays
If decision makers assign stable fitness-related values to options, preference for the most valuable of simultaneously encountered options should be independent of background context (i.e., prior options). The tendency to choose option x versus y should be unaffected by whether the decision maker has already been given a choice between x and y or between x and y . Here, food-hoarding gray jays ...
متن کاملDecoding the Yellow of a Gray Banana
Some everyday objects are associated with a particular color, such as bananas, which are typically yellow. Behavioral studies show that perception of these so-called color-diagnostic objects is influenced by our knowledge of their typical color, referred to as memory color. However, neural representations of memory colors are unknown. Here we investigated whether memory color can be decoded fro...
متن کاملCurrent desires of conspecific observers affect cache-protection strategies in California scrub-jays and Eurasian jays
Many corvid species accurately remember the locations where they have seen others cache food, allowing them to pilfer these caches efficiently once the cachers have left the scene [1]. To protect their caches, corvids employ a suite of different cache-protection strategies that limit the observers' visual or acoustic access to the cache site [2,3]. In cases where an observer's sensory access ca...
متن کاملYellow-breasted Chat and Gray Catbird Productivity in a Fragmented Western Riparian System
—We studied the effects of habitat fragmentation on productivity of Yellow-breasted Chat (Icteria virens) and Gray Catbird (Dumetella carolinensis) in southern British Columbia in a western riparian ecosystem. Nesting dates were later in isolated habitat patches than in continuous habitat patches for both species. We found no direct evidence that habitat fragmentation decreased productivity in ...
متن کاملThe domain specificity of intertemporal choice in pinyon jays.
When choosing between a piece of cake now versus a slimmer waistline in the future, many of us have difficulty with self-control. Food-caching species, however, regularly hide food for later recovery, sometimes waiting months before retrieving their caches. It remains unclear whether these long-term choices generalize outside of the caching domain. We hypothesized that the ability to save for t...
