The diet of Sorex coronatus (Millet, 1828) was studied by the analysis of digestive tracts from 178 individuals collected in Quinto Real Massif, western Pyrenees (north of the Iberian Peninsula). In total, 28 different types of food were determined. The most important prey species, as determined by numerical presence (N) and Simpson's do­minance index (D"), were Chilopoda (%N = 12.8; D" = 21.4), Diptera larvae (%N = 22.0; D"= 17.7), Oligochaeta: Opistopora (%N = 11.3; D" = 12.2), Gastropoda (%N = 7.0; D" = 8.7), adult Coleoptera (%N = 6.9; D" = 8.0) and Hemiptera (%N = 6.0; D" = 5.3). Diets of both sexes were similar. The diet of S. coronatus in the study area was similar to the diet of S. araneus described in the literature.
