Abstract

Feeding of high Pyrenean mountain brown frogs were studied in the pre-wintering period. The main prey is beetles (44'97o), two-winged flies (12'9%) and bees, wasps, ants, etc (11'4%). For the whole of the frogs, the most frequent prey size is the small (smaller than 10 mm). Big frogs tend to consume bigger prey in not ,o. many quantity, while small frogs consume more quantity of preys but smaller in size. From prey way of life, frogs eat mainly terrestrial and aerial preys, although capture of aquatic prey was observed (11'5%) and these preys were eaten inside the water.
