The same time distribution again occurred for aggression and courting acti- vities although, on hot days, they were seen even from the first observation hour (Fig. 5). A strict statistical comparison could not be done because of some discrepan- cies in the recording period during several days and in the number of observed active lizards per day. However, courting and aggressive behaviours seemed to be more frequent in the last study days (Fig. 5). A new behaviour pattern, ten- tatively assigned to a general behaviour category called "Egg-laying", was obser- ved in the last day of recording. This pattern consisted of a movement in which the animal (a female with a folded skin) seemed to be engaged in a sort of ground digging and using the four legs, the result appearing to be a spreading and/or flattening of the soft soil. As this activity was seen to be repeatedly performed by this animal, it was thought that perhaps it could correspond to a step in the later stages of egg-laying.
