Why do some animals have many social partners while others invest in a few strong relationships? Our new @royalsocietypublishing.org paper suggests the answer may be: it depends on the weather ☀️🌧️ 🐑 tinyurl.com/mry3mtpf

Animals are known to prefer kin as social partners. But non-kin bonds are surprisingly common too. So, who forms them, how stable are they & what drives them? In our new @animbehsociety.bsky.social paper we tackle these overlooked questions in free-living rhesus macaques: tinyurl.com/mwsbkjve (1/5)
