Abstract

The article presents the study which examines the diet and trophic position of breeding populations of Double-crested Cormorants from three different lakes in Saskatchewan using stable carbon and nitrogen isotopes. The study aims to determine whether cormorant dietary niche varied by lake and characterize long-term patterns in cormorant diet. It is concluded that cormorant have little economic impact where food webs are diverse in abundant prey species and niches.
