Individual exploratory responses are not repeatable across time or context for four species of food-storing corvid.

摘要: Exploration is among one of the most studied animal personality traits (i.e., individual-level behavioural responses repeatable across time and contexts). However, not all species show clear evidence this trait, particularly so for members Corvidae family. We assessed exploratory behaviour four food-caching corvid species: pinyon jays (Gymnorhinus cyanocephalus), Clark’s nutcrackers (Nucifraga columbiana), California scrub (Aphelocoma californica), black-billed magpies (Pica hudsonia). Contextual repeatability was through examining measures during Novel Environment task Object task, whereas temporal by changes in these over repeated trials. Our results suggest that, corvids, an individual’s contexts or time. Hence, we found no that exploration constitutes a trait corvid. did find differences behaviour, at level, may be explained relative reliance on cached food.
