Ornithological Notes. 
Old Dalby Woods, North Leicestershire, both species exist 
together and have done so ever since the grey appeared, the 
keepers tell me. They do not intermingle, but there is no 
noticeable enmity, and in the former case the keeper tells 
me the red squirrels are increasing though he still shoots 
them. The increase and decrease of the red squirrel thus 
seems, as Middleton indicated in his paper on the grey squirrel 
in the Proceedings of the Zoological Society of London , 1930^ 
to be one of cycles and not connected with the grey squirrel, 
for areas where the grey squirrel does not occur, as all the 
red squirrel haunts around Liverpool show this periodic 
increase and decrease. Red squirrels were on the decrease 
in this area eighty years ago after fairly wide distribution 
(see Byerley’s ‘ Fauna of Liverpool ’ in Proceedings of 
Liverpool Literary and Philosophical Society, 1853-4,) but 
within recent years appear to have reached the end of the 
decrease cycle and are on the increase again. 
ORNITHOLOGICAL NOTES FROM SCARBOROUGH. 
W. J. CLARKE. 
A late House Martin was seen hawking for flies in the shelter 
of the cliffs at Cloughton Wyke on November 27th, 1932. 
On January 23rd, 1933, a melanic variety of the House 
Sparrow visited my garden to feed with other birds ; it 
remained about until February 3rd. Its plumage above and 
below was a uniform sooty black which gave no indication of 
its sex. That it was not coloured by dirt was evident from 
the gloss to be seen on the feathers in certain lights. The 
legs also appeared to be black, but the beak was of the normal 
horn colour. 
An Albino Thrush, all white with the exception of a few 
dark feathers on the rump, has been seen by several observers 
at Scarborough during early February. 
Waxwings appear to have visited Yorkshire in some 
numbers during recent months. I have notes of the following 
occurrences in or near the Scarborough district : — 
Five at Scarborough on November 26th, 1932. 
One at Scalby on November 28th. 
Two at Scarborough on December 1st. 
Five at Rillington, last week in December, 1932. 
a Several ’ at Scarborough, January 19th, 1933. 
One at Scarborough, January 21st. 
Five at Cloughton, January 26th. 
Four at Scalby, January 26th. 
Some of these birds have been seen far within the bound- 
aries of Scarborough, where they visit gardens and feed on 
the berries of the Cotoneaster. Others have been seen eating 
the fruit of the Wild Rose.
