Scaup (Greater / Lesser) · State-by-state

Scaup (Greater / Lesser) hunting regulations.

Greater and lesser scaup are diving ducks (also called "bluebills") with similar appearance — medium-sized birds with iridescent green or purple heads (drakes) and a powder-blue bill. Greater scaup are slightly larger and prefer larger water bodies. Continental populations have declined over decades, leading to conservative bag limits.
