Diet preference
Grains were most preferred by weavers throughout the eight weeks of the experiment followed by fruits and then insects. The number of birds foraging on fruits versus insects differed significantly only at week five while fruits versus grains differed significantly except in week 5 (Fig. 1A, Table 1 & Table S1). More males foraged on fruits and insects than females, but sexes foraged similarly on grains (Fig. 1B, Table 1 & Table S1). Insects had the highest GUD throughout the eight weeks followed by grains and fruits (Fig. 1C), but the GUD of fruits was only significantly lower than grains in weeks 1 and 4 (Fig. 1C, Table 1 & Table S2).
