Abstract
Compared diets of Aythya americana collected from nearshore and offshore zones during winters at the Chandeleur Islands. A greater proportion of redheads from nearshore had food in their esophagus and proventriculus than redheads from offshore. Feeding redheads in the offshore zone consumed more animal matter (42% in esophagus) and less plant material (58%) than conspecifics feeding nearshore (13% animal, 87% plant). Contents of proventriculi showed the same trend. -from Authors
