Graphical representation of the behaviours recorded for A. Tachymenis peruviana and B, C. T. chilensis coronellina, which correspond to videotapes 1, 2 and 3, respectively. The head wobble and tongue-flick behaviours were measured as occurrence or the number of times, and the head backward, rest and displacement, as the total time that snakes exhibited these behaviours at videotapes, which can be accessed at https://doi.org/10.34691/FK2/VSB4D4.
