RED-THROATED DIVER. 243 
BLACK-THROATED DIVER. 
CoLYMBUS ARCTICUS, Linnzeus. 
We only know of one record of the Black-throated 
Diver on the Cheshire coast. In December 1876, 
Mr. J. Bushby of Formby killed one when shooting 
from a boat at the mouth of the Dee, and he was told 
that another had been shot the week before.! 
RED-THROATED DIVER. 
COLYMBUS SEPTENTRIONALIS, Linnzeus. 
In autumn and winter the Red-throated Diver is not 
infrequently met with off the Wirral coast and in 
the estuaries. Brockholes states that, previous to the 
year 1860, it was common in winter at Hoylake;? and 
Mr. L: Jones has a bird in his collection which was shot 
in October 1894, at Hilbre. There is a bird in summer 
plumage from the Dee Estuary in the Grosvenor 
Museum, Chester; and Dr. Dobie has one, still retaining 
a good deal of red on the throat, which was caught in 
a tishing-net in the estuary near Flint on November 
22nd, 1886. In September 1888, a red-throated bird 
and an immature example were shot off the Point of 
Air, at the mouth of the Dee;* and Mr. R. Newstead 
tells us that one was killed on the Dee at Saltney Ferry 
in February 1895. 
We have no record of the Red-throated Diver on 
any of the Cheshire meres, although we have seen
