(1) Smooth newts (Triturus vulgaris L.) and palmate newts (T. helveticus Razoumowsky) are similar in morphology and frequently coexist in the same water body. To determine whether food partitioning occurred during the aquatic phase, their diets were investigated, using a stomach-flush technique, and were compared with food resource availability in a pond in mid-Wales during the months March, April and May. (2) Both numerical and volumetric analyses of the gut contents showed that the two species displayed low food selection and that different prey categories were consumed appr. in proportion to their availability. Food niche breadths were similar in the two species. Stomachs contained fewer prey items but more skin sloughs in March than in April or May. Aquatic crustaceans were the most important prey items in all 3 months, and both species displayed some preference for smaller amphipods and isopods. (3) High food niche overlap was observed between the two species, and between males and females within each species. Niche overlap indices suggest that rather than partioning the food resources, the two species display a convergence in diet. Such a situation may occur when food resources are not limiting for two species with similar morphology.
