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).
