A large-scale study across the avian clade identifies ecological drivers of neophobia
Neophobia (the aversive response to novelty) varies considerably across species and individuals, and can impact adaptability and survival. This study assesses neophobia in 1400 subjects from 136 bird ...

Investigating the relationship between heat-mediated cognitive impairment and antipredator response in a wild bird | Royal Society Open Science
Increasingly frequent heatwaves require animals to spend more time thermoregulating
at the expense of other fitness-related behaviours. Emerging evidence also indicates

@dutourmylene.bsky.social ‘s talk was wonderful, so great to see her back in Perth again!
At CEB seminar today, @dutourmylene.bsky.social walked us through 10 years of her research at the crossroads of animal cognition, behavioural ecology, bioacoustics — exploring how animals code & decode information, use syntax & vocal mimicry, & engage in intra- & interspecific communication 🐦🦅🐓🐍🚶♀️
