Eider Duck on the River Roding, in Essex.—Mr.
Colin Murray, writing in British Birds for March 1918, says :—
On 21 February 1917, I saw a flock of seven Eider Ducks
(Somateria m. mollissima) on the River Roding, and on 10
March 1917, saw ten at the same place. The stretch of river
on which I saw the birds is only a few hundred yards from
the Thames. It is now over forty years since I began to shoot
on the banks of the Thames (chiefly in Essex), and I am well
aware that the appearance of this species on fresh water is
quite exceptional, but I am quite confident that my identifica-
tion is correct. When last seen, they were on the wing, flying
south-east.
