GLMs of group hunting probability. In all three communities, there was a strong positive association between hunting probability and the number of adult males present at a red colobus encounter. At Mitumba, there was an additional positive effect of adult females on hunting likelihood. At Kanyawara, hunts were significantly less likely to occur if at least 1 swollen female was present. Bold italics indicate parameters that were statistically significant (p < 0.05).
