Abstract
Abstract The Green Anole (Anolis carolinensis) has three stereotyped head bob displays (labeled A, B, and C) which it differentially uses during directed hetero- and consexual exchanges. We found free-ranging males advertise (i.e., nondirected signaling) with the same three displays in a complex but consistent manner. From videotapes of 10 adult males recorded across breeding and postbreeding seasons, we analyzed 2308 nondirected displays from two functional subsets of the advertisement context—”monitor” (stationary males signaling from monitoring sites) and “travel” (males signaling while moving between monitoring sites). Using five hypotheses to guide the analysis, we found breeding males (1) used all three display types during both monitor and travel; (2) averaged mostly C displays during monitor (ratio of C:A + B = 4:1); (3) increased A and B displays four-fold during travel (C:A + B = 1:1); (4) averaged a four-fold lower display rate during monitor than during travel (displays/min = 0.8 vs. 3.5, resp...
