NO. 3595 ANOLIS LINEATOPUS — RAND 73 



any particular lizard, several times we saw him unsuccessfully court 

 a female, chasing her and displaying to her. 



No. I's acti\dty reached its highest peak in the earlier part of the 

 morning, perhaps because he was moving frequently to take advantage 

 of patches of sunlight and shadow to thermoregulate. During the 

 heat of the day all the A. lineatopus were less active than they had 

 been in the morning, and they spent longer periods sitting in the same 

 places in the shade avoiding both the direct sun and the perches that 

 had been warmed by the sun. Later in the afternoon, they all again 

 became more active but perhaps not as active as they had been in the 

 morning. 



It was midafternoon before no. I's routine of waiting and Avatching 

 M as markedly interrupted. At 3:48 p.m. he mated with a female that 

 also used the tree as one of her perches. He moved around the tree 

 trunk and came upon her as she rested head downward. He moved 

 up along side of her and attempted to seize the skin on the back of 

 her neck with the tips of his jaws; she moved her head from side to 

 side as if avoiding tliis but did not run. Shortly after he secured the 

 grip and twisted his tail under hers to bring their cloacas into contact. 

 They copulated for about three minutes and then separated. As 

 usual the successful courtship was casual and with little display. 



No. 1 returned to his usual routine until 5:00 p.m., when he moved 

 to the brush heap to display \igorously to another large male that 

 had moved to a stake on the boundary between their home ranges. 

 The resulting dispute lasted about 20 minutes; both Uzards dewlapped, 

 oriented laterally, and bobbed at each other. Eventually both 

 retreated, leaving the stake unoccupied. Several days later, no. 1 

 was able to expand his home range to include this stake but only after 

 a prolonged dispute with the other male. (Details of this dispute are 

 given on p. 48.) 



Soon after this dispute the sun set at 5:44 p.m. and shortly after- 

 ward no. 1 climbed up the tree into the higher branches. He moved 

 out onto the smaller branches and appeared to be selecting a sleeping 

 site. 



Suddenly he came back to one of the main trunks and bobbed at a 

 small unmarked adult female and ran toward her. She jumped to a 

 branch, he followed and seized her by the skin on the neck and walked 

 with her a few steps. They then copulated for two and a half minutes 

 and separated. 



No. 1 displayed and then moments later climbed out among the 

 small branches and foHage. At 6:11 p.m. he was stretched out on a 

 very small branch about 10 feet above the ground, apparently ready 

 to go to sleep. It was already quite dark and by 6:13 it was too dark 

 to see him or to make notes.
