Did you know? Grebes can compress their feathers to reduce buoyancy, helping them dive easily. 📍Mai Po Nature Reserve

Our latest feral cattle paper “Seasonal changes in coat colour and sexual size dimorphism in a subtropical ungulate” is out today in open access @royalsociety.org Royal Society Open Science royalsocietypublishing-org/doi/10.1098/... by myself, Kate Flay, @ghodgson.bsky.social & @amcell.bsky.social

We present the first evidence of seasonal coat colour changes in cattle, with paler individuals in the wet season and darker ones in the dry season, suggesting plastic phenotypes. The main driver of seasonal coat colour appears to be thermoregulation, supporting the thermal melanism hypothesis.

You can find out more about HK feral cattle phenotypes in our paper royalsocietypublishing-org/doi/10.1098/..., and learn more about this unique populations on our website hkcattleresearch.org And let us know your thought about our findings 😀

Water buffalo by birth, supermodel by attitude😅🐃

new In Press from us - "Adaptive behavioural strategies to seasonal challenges by a semi-urban feral ungulate" [water buffalo, Bubalus bubalis]. in Animal Behaviour. very well done @debottam1991.bsky.social & rest of the team! www.researchgate.net/publication/...

Back in Hong Kong after attending #Behaviour2025 in Kolkata and very glad we got to see some of the city's wildlife before our return - some lovely langurs and striped palm squirrels!

This was fun, even if my knees were shaking the whole time! And if anyone at #Behaviour2025 wants to know more about the feral cattle, check out Tania Perroux's talk at 11:19 today in Hall 7 👀 Last day today!

🌿 Native to tropical coastlines, the Sea Mango (Cerbera manghas) thrives where few plants can tolerate salt, heat, and shifting sands. But beneath its fragrant flowers and mango-like fruit lies a potent danger: cerberin, a toxic cardiac glycoside that has caused fatal poisonings across Asia.

Male fiddler crabs show sexual dimorphism, with one claw much larger than the other. This oversized claw helps attract mates, defend territory, and even cool the crab down by releasing body heat while it's active on hot tidal flats

"Allogrooming duration increased with bystander number, suggesting that cattle potentially advertise relationships and status to peers." I absolutey love that cattle are showing off their friendships in front of others royalsocietypublishing.org/doi/10.1098/...

Very excited to announce that our latest feral cattle paper “Strategic third-party interventions in feral ungulate affiliation” is out today in @royalsociety.org Proceedings of the Royal Society B royalsocietypublishing.org/doi/10.1098/... by myself, Kate Flay, Tania Perroux & @amcell.bsky.social

This indicates that cattle pay attention to their social surroundings, and selectively interrupt bonding behaviour. These nuanced social relationships and third-party effects are often only associated with non-human primates, and not usually with livestock such as cattle.

Understanding how ungulates maintain #socialbonds is important for #positiveanimalwelfare and highlights the complex social lives and cognitive abilities of cattle. To learn more about the study, visit royalsocietypublishing.org/doi/10.1098/... or our website hkcattleresearch.org 🐂
