“…Headbobs are stereotyped, which means that they present a defined structure of sequential behavioural units. However, they can show some degree of variation in the duration and/or amplitude of their units among sexes and individuals (Rothblum and Jenssen, 1978;Martins, 1991), social contexts (Martins, 1993;Decourcy and Jenssen, 1994) and populations (Martins et al, 1998;Macedonia and Clark, 2003;Macedonia et al, 2015). Therefore, headbob displays would inform identity, sex, and a social function.…”

Animal communication has a key role in animals and identifying the signals’ function is crucial. Most lizards communicate with each other through visual signals with headbob displays, which are up-and-down movements of the head or the anterior part of the body. In the present work, I described and analysed the headbob displays ofLiolaemus pachalizards in their natural habitat. Specifically, the objectives were to describe the form of headbobs, to analyse their structure and to compare between sexes and social contexts. Adult lizards were video-recorded, registering the sex and the social context, classified as broadcast, same-sex and female-male interactions. The form and structure of sequences and headbobs were obtained. To evaluate the effect of sex and social context on the structure of headbob sequences and on headbob bouts, generalized linear mixed models were made. Intersexual differences were found in headbob display frequency and in the structure of headbob sequences. Lizards in same-sex context made sequences with more bouts, shorter intervals, headbob bouts of longer duration and higher amplitude than broadcast and female-male context. Presence of concurring behaviour such as lateral compression, gular expansion, and back arching occurred simultaneously with headbobs in same-sex context.Liolaemus pachamade four different headbob bout forms, and males were characterised by using bouts A and B, whereas females used bouts D more frequent. Sex and social context influenced only the structure of bouts A and B. The results showed that bouts A and B might be multi-component signals and non-redundant.

“…Several studies suggest that this behavior represents an honest signal that provides reliable information about the sender, such as endurance capacity, bite force, and/or dominance (Baird and Slone, 2003;Perry et al, 2004). Whereas the headbob's structure is stereotyped, the duration and/or amplitude of headbob's units can show variation between sexes and individuals (Rothblum and Jenssen, 1978;Martins, 1991;Vicente, 2018), social contexts (Martins, 1993;Decourcy and Jenssen, 1994;Vicente, 2018) and populations (Martins et al, 1998;Macedonia and Clark, 2003;Macedonia et al, 2015), having a key role in signaling the species, sex, social function, and individual identity.…”

Headbobbing represents one of the primary sources of communication in Iguanian lizards. Here, we describe and analyze for the first time the form and structure of the headbob display in a species of the Phymaturus genus, and compare it across sexes, social contexts, and with other species of its family. We video-recorded Phymaturus palluma adult lizards, obtained the form and structure of headbobs and evaluated the effect of sex and social context on their performing generalized linear mixed models. We found that in P. palluma, headbob is a complex display composed of several units. Headbob pattern is stereotyped, with less than 35% of variation between individuals, suggesting that it is species-specific. Moreover, units vary among sex and social context, revealing that this display is multicomponent and non-redundant following the multiple-message hypothesis. We also found that the headbob pattern was more complex than in other Liolaemidae lizards, which probably is related to the social systems registered in Phymaturus.
