234 BRITISH BIRDs. [voL. XI. 
EIDER DUCK ON RIVER RODING IN ESSEX. 
On February 21st, 1917, I saw a flock of seven Eider Ducks 
(Somateria. m. mollissima) on the River Roding, and on 
March 10th, 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 [ am quite confident 
that my identification is correct. When last seen they were 
on the wing, flying south-east. Cotin Murray. 
GANNET IN RADNORSHIRE. 
A Ganner (Sula bassana) was seen flying over Knighton 
in a south-westerly direction on June 6th, 1911, and was 
captured by a farmer close to Penybont (13 miles from 
Knighton). When caught it was in company with a flock 
of domestic geese. The farmer killed it and brought it in 
to a bird-stuffer at Knighton, where it was seen by me.

RED-NECKED GREBE IN SHROPSHIRE. 
On September 14th, 1917, Mr. James G. Lang watched 
for some time an adult Red-necked Grebe (Podiceps gq. 
griseigena) on the Teme near Ludlow. Concealed by an alder- 
bush, he was able to observe it whilst himself unseen. The 
bird came so close to him that he was able to note every detail 
of the plumage, and particularly noticed the rich red neck 
and conspicuous white patch on the wings. There are always 
several Little Grebes on the water here, but his attention 
was first drawn to the bird in question by its being about 
double the size, though not so large as the Great Crested 
Grebe. The Red-necked Grebe has only twice before been 
recorded in Shropshire—an example in the collection of the 
late ThomasBodenham obtained on the Severn,near Wroxeter, 
about 1850, and another close to Shrewsbury in 1888.

RED-THROATED DIVER INLAND IN LINCOLNSHIRE. 
My brother, the Rev. H. F. Allison, Vicar of Scothern, 
six miles from Lincoln, writes to me: ‘* On December 30th, 
1917, I heard in my stable-yard, in the middle of the village, 
at 4.360 p.m., a harsh ‘Cark, cark,;’ twice repeated. It 
was a Red-throated Diver (Colymbus siellatus) in immature 
plumage: I think a male by its size. As it could not rise,
