RESULTS Signature Display Pattern-Cybotes Anolis cybotes has but a single stereo- typed head bob display in its repertoire. This display pattern is used during non- directed displaying while a male patrols his territory; during male-female court- ship, copulatory, and postcopulatory dis- playing; and during male-male agonistic disputes. The head bob pattern is pro- duced by action of the forelimb and neck muscles (Fig. 2). The bobs of the signa- ture display are rapidly sequenced and of relatively low amplitude. Without bene- fit of frame-by-frame analysis, the display does not appear to have much pattern to it. However, once the pattern is known, it is readily recognized and quite predict- able. The cybotes signature display is com- posed of two sequences of bobbing (the A and B Elements), with the second se- quence repeated during some perform- ances (Fig. 3). The A Element begins with three large bobs (Units 1, 3, and 5). Occasionally a fourth was included (Fig. 4B). This variation was performed by five of the eight subjects and involved 23% of the displays. The A Element concludes with a variable number (3-9, x = 7) of small rapid bobs (Unit 7). If a male began a signature display, it always stopped at the end of an element. Usually the dis- play concluded after a B Element, but 12 displays (18%) finished after the initial A Element (Fig. 5). The B Element is similar to the A, but tends to have one less large bob and fewer smaller rapid bobs (Fig. 3). The B Element is initiated with two large bobs (Units 9 and 11); occasionally two lizards of my sample performed three (16% dis-
