Communication in the Service of Coordinated Action by Spotted Hyenas
summary
A field project fits GPS collars, microphones, accelerometers and magnetometers to every member of a hyena clan and records GPS every second plus continuous audio, and the collars work in real conditions. Pilot on six then 25 collared animals yields concrete results: hunting groups average 1.6 individuals while clan wars and lion interactions average ~15–16, playback of neighbor whoops produces individualistic responses including long patrols, and demographic data show high‑rank sons survive dispersal far better than low‑rank sons. whoops are individually unique
