Our paper on how orangutan mothers plan and alter their space use at personal costs so their offspring may play with similarly aged offspring (independent of kinship and fruit productivity) has transitioned from preprint to peer reviewed publication doi.org/10.1073/pnas...

Maternal ranging strategies facilitate offspring social play at energetic cost in the most solitary ape | PNAS

In most vertebrates, social play among peers is considered essential for behavioral development. Yet in solitary species bearing single offspring, ...

Introducing disappR. The shiny app made by @krishsanghvi11.bsky.social and I to help diagnose and model selective [dis]appearance!! github.com/EIvimeyCook/... Please do try it out and let us know how you get on! (and if you spot any bugs!).

Kākāpō numbers pass 300 for the first time in 75 years. New Zealand’s flightless, nocturnal parrot now totals 325 birds, after a record 90 chicks fledged this season, built on the Department of Conservation’s recovery programme, which started with just 51 birds in 1995. DOC buff.ly/7YIOBd9

Kākāpō population reaches new milestone

The official population of the critically endangered kākāpō has reached a recovery-era high of 325 birds.

🎉🦜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
