The foraging behaviour of a group of semi-wild Red Wattlebirds
Anthochaera
carunculata was examined using a series of experiments. It was found that the birds (a)
had no colour preference for those colours offered; (b) could distriminate between
different sugar concentrations. and (c) rapidly modified their feeding techniques to exploit
new food sources. It could not be determined whether the birds used visual cues or cross
sampling to locate higher concentration solutions. Weaker solutions were still consumed,
partly because some birds were excluded from the richer solutions.
