NB, Statistics were performed using one-way ANOVA with Tukey–Kramer multiple comparison test; before foraging is abbreviated as BF; after foraging is abbreviated as AF; time points 0–120 are in minutes. p < 0.05 are considered significant and multiple comparison post-hoc test was performed to control the chances of resulting increase of statistical significance due to running many tests simultaneously. “ns” stands for not significant (p > 0.05).
