Nuttall made but slight mention of this species, supposing it to 
be a straggler from the Pacific. He reported it as visiting the 
Middle .States in winter, and stated that the gunners of New Jersey 
and Pennsylvania called it the Sand-shoal Duck. The flesh, he 
add.s, is dry and unsavory. 
The majority of the ornithologists of the present day believe 
that the species has become extinct, though some forty years ago 
it occurred regularly all along the coast from Labrador to Dela- 
ware, and nested in the lower fur countries. 
The last example known to have been taken was shot near 
Elmira, N. Y., in 1878. Previous to that date one had been taken 
on Long Island in 1874, and another at Grand Menan in 1871. 
As the bird was shy and difficult to approach, a strong swimmer 
and of rapid flight, its extinction is a curious phenomenon, and 
unaccountable. There are only thirty-three specimens known to 
be preserved in the museums of America.
