NO. "505 ANOLIS LINEATOPUS — RAND 71 



branched at the ground into six trunks, each about three inches in 

 diameter. It also included part of an adjacent brush heap and a 

 small log and three nearby fence posts. 



We started observations at 6:05 a.m., when it was just light enough 

 to make notes. The nocturnal frogs were still calling but the cocks 

 had started to crow and mockingbirds were singing. It was still 

 cool (19° C at 6:15). I could see no anoles yet, though I knew from 

 previous nights that many were asleep in the small tree, stretched 

 out along the twigs or leaves near the ends of branches. 



At 6:17 a.m. I located the first A. lineatopns, an adult male, still 

 in his sleeping position on top of a leaf at the end of a branch but 

 already awake with his eyes open. It was light now and, three 

 minutes later, he left his sleeping site for the inner branches of the 

 tree. During the next 20 minutes, there was considerable movement 

 in the tree as anoles moved about and departed for the adjacent 

 brush heap. The individual we had decided to observe, no. 1, ap- 

 peared at 6:22 a.m., moving down one of the tree trunks and then 

 across to the brush heap. After about 10 minutes he moved down 

 into the brush heap so that he was almost completely concealed by 

 the tangle of branches above him. He ignored the other anoles 

 moving about him, including a large male that came down the tree 

 and jumped into the brush heap. 



By 7:00 a.m. both tree and brush heap were quiet again and none 

 of the A. lineatopus were sitting up on the perches where we usually 

 saw them during the day. They had all left their exposed sleeping 

 sites for more concealed spots, where they were waiting quietly. 



The sun rose and at 7:16 a.m. its rays struck the brush heap, but 

 no. 1 was still in the shade. He waited only a minute and a half 

 before moving out into the sun and, three minutes later, climbed up 

 onto the surface of the brush heap to sit in partial sunlight for a few 

 moments before moving toward the tree and into full sunlight. About 

 the same time other A. lineatopus also began to move, and the area 

 that had appeared empty moments before was now fuU of anoles 

 basking in the sun. Two large males began displaying to each other 

 across the boundary of their home ranges in the brush heap. Though 

 they continued this for about 20 minutes and were less than five feet 

 from no. 1, they were outside of his home range and he ignored them. 



By 8:00 a.m. it had warmed up considerably (24° C at 8:10 a.m.) 

 and no. 1 was moving about frequently and displaying, both dew- 

 lapping and bobbing. Though I saw him bob once shortly after he 

 first appeared (6:23 a.m.), he did not display again for over an hour 

 and did not begin displaying frequently until ho had been sitting in 

 the sun for some minutes. 



About 8:30 a.m. no. 1 dashed for the tree, ran up and, with pauses
