Addressing variability in estuarine food density for American black ducks

ABSTRACT Habitat limitation and availability of food energy may be the cause of decline in American black duck (Anas rubripes) populations. Estimating food availability is a critical step in developing winter carrying‐capacity estimates for black ducks. Recent research has estimated the biomass and...
