Receiver foraging effort represents mean time spent foraging at per individual. Cells marked in bold represent 'response errors' where individuals exerted more foraging effort in the incongruent field. Details of how cumulative values were calculated are found in Figure 3. (B = bark, P = peep, PY = peep yelp, Y = yelp). CVO: Cumulative value (ordinal); CVC: Cumulative value (cardinal); Kiwi bias: Relative bias towards the kiwi field.
