Least-squares mean net return rates for sand monitor hunting (s.e., 95% CIs) derived from LS mixed model with forager ID as random effect, controlling for rainfall, season and cooperation, n = 750 bouts; use rank effect test F-ratio = 4.16, p = 0.0062. Values connected by the same letter are not significantly different (Student's post-hoc t-test, p < 0.05).
