🎉🦜NEW PAPER ALERT 🦜🎉 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)

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

There is order in pandemonium 😜 1- We show that wild SC-cockies have sex & age structured hierarchies, stable for at least 3 years 🏆 2- We provide guidance on how to choose the right threshold for your data when using rElo.

It turns out there is order in the apparent cockie chaos! In a new paper from the Clever Cockie Research Group; @julia-penndorf.bsky.social and co-authors show how roost of wild SC-cockies exhibit linear dominance hierarchies that are stable over 3+ years. www.sciencedirect.com/science/arti...

New paper alert! 🦜 We gave wild cockatoos puzzle boxes across Canberra’s urban gradient. The finding? Urban birds approach faster, but are not better solvers. Our results suggest that urbanization shapes neophobia independently from cognitive performance. Read it here: doi.org/10.1093/behe...

Cities are challenging places for wildlife, but some species, like sulfur-crested cockatoos, adapt by finding new ways to feed and solve problems. We studi

A few days short of my 8(!!) year anniversary in the Aplin lab, it‘s time to say goodbye to a truly amazing lab & start a new, exciting, chapter! R: 1st day of PhD fieldwork &1st time having a bird land on me (2018). L: soaked through (but happy!) postdoc with the same bird, Tobruk (103).
