Memory for options’ metrics is independent from context. a Interval timing in the experiment shown in Fig. 2a. Pecking rates peaked at the veridical time of reinforcement in all four options. Notably, although starlings preferred C(10 s) to B(10 s) (see Fig. 2a), the temporal location of reward was unaffected.

Options were defined by their profitability (n pellets / t seconds of delay), as indicated in the ratios shown in the legend. Rate of responding in probe trials (mean ± SEM, n = 9 birds) differed between options with different delays, but not between options with different food amounts.
