PhD studying playful Goffin's cockatoos 🦜

Opportunity to pursue a doctoral thesis in the Goffin Lab and the Kea Lab The research will focus on play, exploration, and problem-solving abilities in cockatoos and kea. If exploring the minds of other species fascinates you, I highly recommend this opportunity.

NEW PAPER! 🐒 Cooperation experiments in animals are often done with one cooperation apparatus, creating a specific highly monopolisable setting. We found that presenting multiple apparatuses significantly changed macaques' partner preference compared to one apparatus. doi.org/10.1016/j.an...

Our “Bird Research at Schönbrunn Zoo” day went super well! We had an official guided tour, talks by Barbara Steininger on bald Ibis and @guillmcivor.bsky.social on crows, “Bird Behaviour Bingo,” a picnic and a photo contest 😍🪶☀️

There and back again... A year ago, I started a new field study with long-tailed macaques in tropical Bali, Indonesia. Then, I visited the snowy prairies in Alberta, Canada. I've met many great people and playful monkeys along the way. I'm very thankful for all the support during this adventure 🗺🐒

🎉🦜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
