Resumo: Observations on the foraging activity and diets of four sympatric rainforest lizards were used to test previous generalizations based mainly on studies on lizards from arid areas. In contrast to lizards studied in arid areas, an ambush predator (Uranoscodon superciliosa, Iguanidae) eats more hidden and slow moving prey than the most active forager (Kentropyx calcarata, Teiidae). Plica umbra (Iguanidae), an ant specialist, has similar foraging intensity to Anolis punctatus (Iguanidae) and is more active than U. superciliosa, which are generalist insectivores. Plica umbra does not have the behavioral and morphological adaptations for myrmecophagy that commonly occur in desert lizards. Uranoscodon superciliosa also does not specialize on large prey, as predicted for extreme "sit-and-wait" lizards in tropical rainforests. Differences in the consequences of foraging mode for the diet of lizards between arid and forest areas may be affected by differences in the availability of prey and their distribution in the environment.
