Factors influencing wintering turfgrass field use in Atlantic brant
Wildlife Biology, EarlyView.Atlantic brant Branta bernicla hrota increasingly use turfgrass fields, such as baseball fields and golf courses, throughout their wintering range. Most studies have focused on their primary food source, submerged aquatic vegetation, while studies of other goose species worldwide have examined field use in different contexts, including agricultural ...
