THE BIRDS OF BRECONSHIRE. 125 
Mr. Crawshay tells me that he has 
seen a flock of twenty females fishing 
together on the Usk at Buckland but the 
males were scarcer. I see small flocks 
often in the spring near this house on 
the Usk, and it has been killed on the 
Wye, near Gwernyfed, by Col. Wood’s 
keeper. Two, both females, were sent by 
the Colonel to me for identification. I 
need hardly add that it is an exceedingly 
swift flyer. Williams gives the Welsh, 
Hwyad ddaneddog. 
GREAT NORTHERN DIVER, 
Colymbus glacialis. 
Many years since the late Mr. Duncan, 
of this town, shot a beautiful male bird 
on Newton Pool, close to Brecon. The 
late Mr. David Thomas had also a pair 
from the Usk near Brecon. Mr. A. 
Crawshay has observed it at Llangorse, 
and in the winter of 1881 one was killed 
there and two others seen. Some speci- 
mens have also from time to time been 
obtained on the Wye, near Hay and 
Glasbury.
