The amount of food eaten by lizards at high altitude is less during the monsoons compared to the non-monsoon months. Temperatures are lower during the monsoons and lizards were observed to spend much of their time thermoregulating. At low altitude, adult males and immatures ate no less food during the monsoons. In spite of increased cloud cover, ambient temperatures were high enough that there was no need for protracted ther- moregulatory activity. Low altitude adult females, however, showed a marked decrease in amount of food eaten. Ten of the 12 individuals in the sample were gravid with nearly mature oviducal eggs, but the two nongravid females also had eaten little. Fig. 21. Diet of hatchling high and low altitude A. tuherculata. Sample sizes as in Tables 6-7, symbols as in Fig. 18. DAILY AND SEASONAL ACTIVITY Hourly censuses throughout the day for differ- ent months revealed varying degrees of activity (Figs. 22-27). Counts included all visible indi- viduals regardless of the type of activity. Most observations were of inactive individuals; adults engaged in few prolonged periods of active forag- ing. Rather, they occasionally dash out from a favorite basking place or look-out point and promptly return to it or another point after each sortie. Juveniles we
