New paper from the lab by Angela Pitera (last chapter of her PhD dissertation!) showing that food-caching chickadees rely on their own spatial memory when learning a spatial task and not on social learning.

Social group membership does not facilitate spatial learning of fine-scale resource locations - Behavioral Ecology and Sociobiology
While many animals use social information to discover novel food sources, the importance of social information availability in the process of learning and remembering specific, fine-scale resource locations remains unclear. Benefits of using social information may vary with an individual’s ability to learn and remember resource locations and environmental conditions. We experimentally tested whether animals use social information from group mates to find and learn resource locations using wild, food-caching mountain chickadees (Poecile gambeli). We tested spatial learning and memory performance by tasking birds with learning the location of one rewarding feeder out of eight using two treatments: (1) birds in the same social group shared the same feeder and (2) social group members had to learn different feeders. We found no evidence that access to social information from close social associates facilitates spatial learning and memory as there were no differences in performance between treatments. Most chickadees used personal information to find their feeder, but there were low and similar rates of social information transmission for both treatments. Our results suggest that chickadees use social information from conspecifics regardless of group membership or familiarity but primarily rely on independent learning and personal information when foraging in a familiar area.

My take on the amazing paper by Hanna Payne and Dmitriy Aronov on activation of hippocampal place codes by gaze in food-caching chickadees.

Congratulations Dr. Sanjay Prasher (recent Hobson Lab PhD) on a new publication! We explored how memory, attention, and social preferences affected social plasticity, using an agent-based modeling approach. doi.org/10.1093/icb/... (or message me if you want a pdf!)

Image shows a photo of first author Sanjay Prasher, Hobson Lab and University of Cincinnati logos, and three images of figures from the paper (a flow diagram of the agent-based model, heatmaps showing how social interactions towards a focal individual changed as a function of memory, attention, and social preference, and lineplots showing how group size modulated these effects)

When we have so many painful and dangerous things to grapple with, it makes the joyful things that much more precious. Seek them out, save them, share them!

Here’s one I’m *really* excited about: www.okaybutbirds.com by the hilarious & charming @drscottataylor.bsky.social

Adult mountain chickadees are molting heavily - but juveniles look much ‘cleaner’

New publication! 🚨

If you're looking for a paper on what great tits eat then this is for you! 🦋🐛🐞🪲🐦

We looked at variation in diet using DNA metabarcoding and found lots of differences between adult and young birds and between habitat types.

Schematic of the structure of the paper. We looked at dietary differences between ages and sexes, seasons and habitat types. We looked at the identity of prey in the diet and the number of dietary items.
