The Irish Nahirahst.

Black-headed Gull as a breeding species at the present day 
is explained by the want of lakes and bogs, where immense 
colonies exist in Ireland. It is abundant in Man during all the 
year except summer. In the body of the book Mr. Ralfe says 
of the Common Gull, " It does not seem probable that any nest 
in Man, though it has colonies very near our coasts," but from 
a note in the Addenda (p. 315) we learn that on 23rd June, 
1904, an undoubted egg of the Common Gull was taken on the 
Manx coast from a nest containing three eggs. The date is 
very late ; in Ireland the young are sometimes hatched the first 
week in June ; and further confirmation of this very interest- 
ing and important point will be looked for. Although the 
Lesser Black-backed Gull breeds in some numbers in Man, the 
Greater Black-backed is not yet kno\vn to do so, though 
there must be many suitable places for it. In Ireland both are 
resident, the latter in very much smaller numbers however. 
In Man there is only one comparatively small colony of Kitti- 
wakes, on the Calf, although suitable nesting places must be 
numerous. In Ireland, though local, it breeds in some vast 
colonies. The Herring Gull seems to be the dominant sea 
bird of Man. 
The Razorbill, Guillemot, Black Guillemot, and Puffin all 
seem to occupy relatively the same position in Man that they 
do in Ireland. The lyittle Grebe is as plentiful in Man as 
could be expected. 
If we now take the Types of Distribution " as detailed by 
the late A. G. More in his valuable paper " On the Distri- 
bution of Birds in Great Britain during the nesting season' " 
we get the following result, taking only those birds which 
u7idoubtedly breed in both islands and leaving out all " not 
proven " cases.
