FORAGING BEHAVIOR OF SURF SCOTERS (MELANITTA PERSPICILLATA)AND WHITE-WINGED SCOTERS (M. FUSCA) IN RELATION TO CLAM DENSITY: INFERRING FOOD AVAILABILITY AND HABITAT QUALITY

ABSTRACT Birds are known to modify their foraging behavior in relation to food availability. Once understood, these relationships can be used to draw inferences about relative food availability and habitat quality. We measured foraging behavior of Surf Scoters (Melanitta perspicillata) and White-win...
