All birds were over 80% correct during their last 10 training trials. In both species, performance did not decline when novel stimuli were used without reward (probe trial 1), but performance dropped significantly and to random levels when UV was removed from the ambient light (probe trial 2).
Statistics show one sample t-test on difference in performance between the last 10 training trials and probe trials.
