Figure 2.

Foraging and aggressive behaviours for group members (a,c,e) and index birds (b,d,f) at low (light grey) or high (dark grey) feeder density throughout the course of an experimental epidemic. Asterisks indicate weeks with significant differences across feeder densities in post hoc tests (see Results). Feeding behaviours were log₁₀ transformed for analysis, but raw data are shown here. Error bars represent standard error. Asterisks indicate a significant difference between treatment groups.
