Does anyone know why when new breeding groups are formed they typically pick 1 male and 3 females? Just a pattern I’ve noticed and been curious about why the SSP does that!
Females feel supported when other females are present; but with regards to having three females in a troop specifically, the silverback will often have a favourite female. Having three females rather than two ensures one single female isn’t on the outside.
It also safeguards against the reduction of a troop to 1.1 adults should one female unexpectedly die (which unfortunately happened in an Australia Zoo earlier this year).
