Led by @hanjabrrr.bsky.social, @damienfarine.bsky.social, and I, we combined ECG and GPS tracking from a whole group of vulturine guineafowl to show that collective movements, and especially attempting to lead under disagreement greatly increased Heart Rates.

Animal research revisited – the case of behavioural studies
Animal research is a matter of intense public debate, with some people supporting and some opposing it. Drawing from examples of behavioural biology, we argue that such an ‘all-or-nothing’ debate fall...

Social transmission of stress in zebra finches bird: "Effects were stronger in colonies with a greater proportion of stress-treated individuals. Stressors can reach beyond directly exposed individuals by also affecting their group mates."

🚨 Evidence for social transmission of stress in zebra finches

In this huge experiment, Hanja Brandl experimentally stressed zebra finches in replicated colonies, and found that their group mates (who were not exposed) showed similar behavioural responses.
