In some old charts, particularly by the Dutch, whose name for a headland is kappe, it is also called skape and scaup.
Another of the sea-ducks, the scaup, is also taken in large numbers in this way.
These ducks are perhaps better known as Blue-bills, than as scaup Ducks.
In flight, the dark wings are different from the white-edged wings of scaup.
The scaup is so called from its feeding on 'scaup', a northern word for a bed of shellfish.
scaup Ducks begin to arrive off our more northern coasts in September, but not until a month later in the south.
The scaup came down the sky in dark masses, giving a rippling purr as they flew.
The food of the scaup Duck consists largely of molluscs, but crustaceans and marine plants are also eaten by this species.
All of the first three species are abundant, as are also the scaup, baldpate, redhead and Bahaman pintail.
In its habits generally, it very closely resembles the scaup Duck, a species whose company it often keeps.
