ANOLIS LINEATOPUS — RAND 49 



No. 6 down into brush heap out of sight. 



No. 6 moves directly toward brush heap, stops one foot away; it 



No. 1 dewdaps. No. 6 is now 3 feet NNW of stake. 

 No. 6 runs by stake, but angling toward No. 1, to 2 feet northeast 

 of stake; No. 6 dewlaps, crests full up; No. 1 dewlaps. 

 1625 hrs. Both display. 



1631 " No. 6 moves diagonally a short distance towards No. 1. 



1632 " No. 1 dewlaps; No. 6 bobs. 

 1634 " No. 1 dewlaps. 



1637)i>" No. 1 twitches tail, jumps down into brush heap away from No. 6; 

 No. 6 moves a bit closer; No. 1 jumps back to stake obliquely approaching No. 6; 

 both disi:)lay dewlapping. 



1639 hrs. No. 6 moves a bit closer, mouth open, tongue out; they are now 

 about 1 foot apart, No. 1 on stake. No. 6 on a branch in brush heap.

1653 " No. 6 moves about 6 inches further away. 



1656 " No. 6 moves back to the north part of the brush heap, then down 

 into brush heap, bobbing. 



No. 1, apparently as a result of this encounter, established his claim to the 

 stake and thereafter visited it frequently without being challenged by No. 6, 

 which I did not again see on the stake. 



17 January — 0900 hrs. No. 1 is on stake. No. 6 on his perch in north part 

 of brush heap. Neither has crest up nor is displaying more than usual. 



Anolis lineatopus may expand its activity range slightly at the 

 expense of another as did the adult male in the case above, or it may 

 drive the original lizard out completely as did the juvenile female in 

 the following example. 



(4) 27 January— Barbican brush heap [fig. 5], 900-1020 Ilrs. No. 148, small 

 female, invaded the activity range of No. 163, small female, and drove her out 

 of it. These lizards have occupied adjacent activity ranges for at least a week. 

 Until today I had seen no conflict between them. 



Two small females, Nos. 163 and 161, have divided the small brush heap 

 between them. No. 161 on the west side and No. 163 on the east side. No. 148 has 

 spent its time both north and south of this brush heap, passing without hindrance 

 through it along a central branch which lies between the activity ranges of Nos. 

 163 and 161. 



This morning No. 148 entered the activity range of No. 163 and bobbed 

 at her. No. 163 bobbed back. No. 148 jumped in No. 163's direction and 

 No. 163 retreated east and eventually out of her activity range. 



Between 900 and 1000 hrs. while I watched. No. 163 tried twice to re-enter 

 her old activity range and each time No. 148 drove her out. They never came 

 to grips or even displaying at close range. A dash by No. 148 in No. 163's 

 direction sent No, 163 fleeing.
