So grateful for my amazing collaborators who made this project possible. And of course our cockies—especially Heidi (wing tag 48, on pic below) who helped supervising this pandemonium 🦜

Does proximity of breeding hollows influence foraging associations in wild cockatoos?

The behaviour spread to neighbouring roosts located between 2-10 km apart within days.
(🧵4/6)
Age and sex did not influence whether individuals socially learned, but did influence *how* they learned:
- juveniles were conformists, disproportionally preferring the most chosen colour
- adults preferentially copied members of the same roost
(🧵3/6)
At 2 roost sites, we trained 2 birds to eat dyed almonds (red/blue). Once presented to the group, naïve individuals ate almonds within minutes. In the control group, almonds were only eaten after a visiting bird introduced the behaviour (>99% of solves through social learning 🤯)
(🧵2/6)
Finally, how individuals extracted almond kernels ?
(>500 videos, 147 birds, 5 roosts)
Openings were more similar :
- between close-by roosts,
- between highly connected roosts
- between social associates
This indirectly suggests that openings are likely to also be socially learned.

We find that male—but not female—winter social associations are correlated with breeding location; males bred closer to their winter associates, and more socially connected males tended to breed closer to the roost location.

Which social learning biases underly the acquisition of novel food in wild parrots ?
We (@lucymaplin.bsky.social, @bjjbarrett.bsky.social, @sonjawild.bsky.social, @drjohnmartin.bsky.social) presented >700 cockies with a novel, artificial food (🧵1/6)

Hi all! I am new to Bluesky so I am just posting some of my earlier research.

Adopting novel food is vital to colonize novel environments, but what is the role of social learning? Study of urban #cockatoos by @clevercockierp.bsky.social shows them to rapidly adopt novel food via #SocialLearning, with juveniles showing conformist preferences @plosbiology.org 🧪 plos.io/4uq6NVq

GPS is relatively new. So how can we study long-term animal movements? Our approach in @Ecology_Letters transforms historic location records (pre-GPS) into valuable data, revealing capuchins' responses to #climate and demographic change. #openaccess...
