Abstract
Major foods of six species of sympatric shrews from Sagamook Mountain. New Brunswick, in order of importance by percentage of total volume were Blarina brevicauda: earthworms, slugs and snails, and insect larvae; Sorex palustris: insect larvae, spiders, slugs and snails, and flies; Sorex gaspensis: insect larvae, spiders, flies, and beetles; Sorex fumeus: insect larvae, earthworms, and moths; Sorex cinereus: insect larvae and spiders; Sorex hoyi: insect larvae, beetles, and spiders. These rather striking differences in the diets of the various species of shrews in this study suggest that the food resources were being differentially exploited.
