Diet and Foraging


The Guanay Cormorant feeds primarily on large schools of Peruvian silverside (Odonthestes regia regia), Peruvian anchovy (Engraulis ringens), and mote sculpin (Normanichthys crockeri) in the rich waters along the Pacific Coast of South America (Zavalaga and Paredes 1999). They forage during the daylight hours, usually in groups. The cormorants can dive to depths of up to 74 m, with a mean maximum of 33.9 ± 2.6 m, in search of food (Zavalaga and Paredes 1999).
