Activity of Black Ducks nesting along streams in northeastern Nova Scotia

Norman R Seymour

Birds used the associated estuary to feed and females took broods there. Males defended territories along streams but left territories and mates early in incubation. The pursuit flight was the main mechanism of territorial defence.
