(a) Vision experiment. Number of visits made by the birds 2 and 5 min after their first choice to the cylinder with the systemically herbivore‐induced branch and to the cylinder with the uninfested control branch (2 min: S = 79, p = .072; 5 min: S = −16, p = .79), and (b) the total time spent by the birds (2 min: S = 134.5, p = .11; 5 min: S = −14.5, p = .86) on either type of cylinder during the 2 and 5 min after the first choice. (c) Olfaction experiment. Number of visits made by the birds 2 and 5 min after their first choice to the cylinder with the systemically herbivore‐induced branch and to the cylinder with the noninfested control branch (2 min: S = −39.5, p = .37; 5 min: S = −0.5, p = .99), and (d) the total time spent by the birds (2 min: S = 30, p = .66, 5 min: S = 16, p = .77) on either type of cylinder during the 2 and 5 min after the first choice.
