Abstract

Spring body condition is an important determinant of reproductive success in arctic-nesting geese. However, greater snow geese (Chen caerulescens atlantica) are unlike other geese in that they feed during the laying period and rely minimally on stored nutrient reserves. Because laying is a period of high nutrient requirement for females, I determined the amount, species composition, and nutritional quality of food consumed by geese while nesting at Bylot Island, Northwest Territories. I assessed diet and food consumption by examining esophageal contents and measuring the ingesta mass of geese collected by shooting. I also evaluated food quality by determining protein and fiber content of food plants collected at the same time
