INTRODUCTION The Chacoan cavy (Pediolagus salinicola) is an endemic species of the Chaco region, ranging from western Paraguay to central Argentina. It is closely related to another species, the mara (Dolichotis patagonum), with whose range it overlaps only slightly in central western Argentina (Cabrera 1961). In size, shape and cursorial adaptations, Chacoan cavies show close resemblances with rabbits (VaugMammalia, t. 56, n° 4, 1992. ban 1978). The Chacoan cavy prefers open, semiarid woodland and shrubland. It is diurnal and does not dig burrows, sheltering instead in hollow dead logs, rotten logs or in burrows dug by other animals. Aside from very general descriptions (e.g., Cabrera and Yepes 1960, Mares et al. 1981) there is no information on its biology and diet. Here we study seasonal changes in the composition of the diet of the Chacoan cavy in the western Chaco of Argentina. STUDY AREA Field work was conducted at Campos del Norte and Salta Forestal ranches, located near Joaquin V. Gonzalez, (25°05J S, 64° 10' W), Salta Province, Argentina. The climate of the region has two distinct seasons: a humid, hot summer (November-April) and a dry, cool winter (May-October). Total annual rainfall averages 500 mm. Annual average temperature
