Abstract
The feeding ecology of a population of the Wall Lizard Podarcis muralis was studied in the West of France from 1982 to 1983. The consumption and the availability of prey have been compared considering taxonomic categories and size classes. The wide taxonomic spectra, the great size range of ingested prey, and the important temporal variability of the diet stressed the opportunistic feeding behaviour of this species. However, a detailed comparison between the consumption and the availability of prey, and the comparison with another population (Mou et Barbault, 1986) reveal some degree of prey selection, which modulates the trophic opportunism characteristic of this species.
