Current 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 کاملCalifornia Storms as Viewed by Sacramento Radar
The WSR-57 radar a t Sacramento provides an opportunity to observe mountain effects on precipitation and on radar echo patterns. Radar patterns representing a wide range of weather situations are described and interpreted in light of concurrent gage precipitation measurements. The frequent underestimation by radar of rainfall on windward slopes is attributed to the small drop size and low forma...
متن کاملDifficulties when using video playback to investigate social cognition in California scrub-jays (Aphelocoma californica)
Previous research has suggested that videos can be used to experimentally manipulate social stimuli. In the present study, we used the California scrub-jays' cache protection strategies to assess whether video playback can be used to simulate conspecifics in a social context. In both the lab and the field, scrub-jays are known to exhibit a range of behaviours to protect their caches from potent...
