Spatial Learning and Memory, Cognitive Flexibility, and Rule-Learning in Food-Caching Mountain Chickadees (Poecile gambeli) Across an Elevational Gradient
… flexibility, and rule-learning in wild, food-caching mountain chickadees ( Poecile gambeli ). I found that chickadees updated information about their environments more frequently in harsher, less predictable winter environments than in milder, more predictable ones. I showed that …

The Causes and Consequences of Complex Behavioral Trait Variation in a Resident Montane Bird
… mechanisms. In this study, I found that food-caching propensity and nest building propensity are not only highly repeatable behaviors within individual female chickadees but also highly correlated. This suggests that food caching, a trait under selection that has a strong underlying …

Sex and seasonal variation in hippocampal volume and neurogenesis in the eastern chipmunk, Tamias striatus
… in tandem with spatial behaviours such as food-caching and mating. However, few studies have simultaneously compared across sex and season, and the literature contains inconsistencies. The present study examined sex and seasonal differences in HPC volume and neurogenesis in the eastern …

I See, Therefore I Think - The Role of Observed Realities on Cognition in Rooks (Corvus frugilegus) and African Grey Parrots (Psittacus erithacus)
… in other corvids, which display advanced OP and food caching. Secondly, another ability requiring secondary representation is mirror self-recognition (MSR), but evidence from birds is contested and contradictory: Often, they do not behave consistently with either self-recognition or perceiving a …

Recovery of cached food by captive blue jays (Cyanocitta cristata)
… nut dispersers in North America. To date, the caching and recovery behaviors of four North American Corvids have been documented, n10st notably Clark1s Nutcracker (Nucifraga columbiana). Blue Jays (Cyanocitta cristata) are important dispersers of Quercus, Fagus, and Castanea nuts in eastern …

Elements of episodic-like memory in non-human animals: theory, methodology, and evolution
… with experimenter made ‘caches’ (i.e., food underneath cups), thus providing converging lines of evidence across multiple paradigms that caching corvids possess an episodic-like memory ability. As such, episodic-like memory is often thought to be an adaptation to the cognitive demands of …
