fully feathered. It takes to the water early in August, 
having become very fat; this condition is manifest even in 
the downy stage. 
There are several breeding-stations south of the Isle of 
Man, notably on the islands off Pembrokeshire, on Lundy, 
and on the Scilly Islands. It would appear that this species 
does not breed anywhere along the eastern side of Great 
Britain. 
On many of the Scottish Islands, including the Inner 
and Outer Hebrides, the Orkneys, and the Shetlands, it 
nests abundantly. 
In Ireland, it breeds on many of the islands off the 
north, west, and south coasts, and more sparingly on the 
east side.! 
I found the Manx Shearwater extremely plentiful in 
summer off the Kerry coast, where the largest Irish colonies 
exist. Regarding its distribution as a_breeding-species 
round the Irish coast, Mr. Ussher states, ‘‘ There are prob- 
ably many unknown breeding-haunts on remote spots, 
especially in the West, as a bird which never shows itself by 
daylight on land is difficult to discover; but as evidence of 
its general distribution in June and July, I may mention 
that during the cruise of Mr. H. Evans’s yacht ‘“‘ Aster ”’ in 
1899 Mr. Barrett-Hamilton noticed some on every section 
of the Irish coast ’’ (‘ Birds of Ireland,’ p. 392). 
Geographical distribution.—Abroad, the Manx Shear- 
water breeds on the Faroes, and is common in the south- 
west of Iceland; it may also be met with along the 
Norwegian coast and the North Sea generally. It is dis- 
tributed over the Atlantic in summer, though along the 
American side it would seem that it is rare.” Southward it 
1 On May 15th, 1889, a man brought me a Shearwater which he 
pulled out of a hole on Bray Head, co. Wicklow. On dissection I found 
an egg ready for expulsion with the shell fully formed, This appears to 
be strong evidence that the bird was taken from its nesting-burrow, and 
it is a matter of regret that it was not captured some hours later when 
the egg would have been laid, and another breeding-locality added to the 
few on the mainland on the east coast of Ireland. 
2 Mr. Saunders’ remarks (Man. Brit. Birds, 2nd Edit., p. 742) that 
he saw two birds, which might have been Manx Shearwaters, outside 
the Straits of Belle Isle, on August 13th—14th, 1884. On August 15th 
—16th, and on the return journey on September 3rd—4th, 1906, I passed 
through the Straits, outside of which were large numbers of Great 
Shearwaters, and not a few Sooty Shearwaters, but I failed to detect 
« single Manx Shearwater among their number.
