The effect of gaze on the response time and the second response distance measured in 13 foraging magpies.

*Statistical results after removing the data from 3 magpies that were tested with either one of the treatments were qualitatively the same. The interaction between the gaze treatment and type of response was not significant for either response time (F1,17 = 0.12, P = 0.729) or second response distance (F1,17 = 0.21, P = 0.656). Similar to the results in the table, the effect of the treatment (i.e. gaze or non-gaze) was significant for response time (F1,17 = 10.48, P = 0.005) but not for second response distance (F1,17 = 1.69, P = 0.211).
