620 MIGRATION AND OTHER ORNITHOLOGICAL NOTES. 
Little Tern (S. minuta). — First few arrived at nesting- 
haunt on April 30th. Not so many bred near here in 1911 and 
1912 as in 1910 ; the reason for this is not obvious. 
Sabine’s Gull ( Xenia sabinii). — Mr. Patterson reported to 
me a bird which he saw and sketched at the Harbour's mouth, 
at Gorleston, on October 6th, which could have been none 
other than a young bird of this species. 
BLACK-HEADED Gull ( Larus ridibundus). — Many moving 
south on January 16th. Some here with brown heads on 
February 2nd. 
Common Gull (L. canus). — Some at Easton Broad by 
August 6th; many adults there on February 11th, but all had 
gone by March 10th. 
Herring Gull (L. argentatus). — Many arrived, coming 
from N.W., on July 27th. 
Guillemot {Uria troile). — On February 11th, I found two 
moderately fresh Guillemots in the tide mark, with black throats. 
As there was no sign of moult in these specimens, I am inclined 
to think that they had for some reason (disease ?) not performed 
a full autumn moult, or perhaps they had performed an abnor- 
mally early spring moult. 
Little Auk ( Mergulus alle). — The cold snaps and strong 
S.E. wind in January and February brought to our shores, dead 
and dying, more than an average number of Little Auks. The 
first was found on January 23rd, and between that date and 
February 11th, I have notes of more than twenty specimens 
found on the tide mark in this neighbourhood. It is noteworthy 
that it was not until five days after the strong winds and cold 
weather had subsided that the first derelicts drifted in. 
Great Crested Grebe ( Podicipes cristatus ). — Some on 
Breydon during the cold weather, February 2nd. From the 
stomach of one obtained in Yarmouth Market I took a Smelt 
5j inches long. 
Slavonian Grebe (P. auritus). — This was another cold- 
weather visitor to our coast. One at Pakefield, January 30th ; 
one on the tide mark, February 4th ; two at Easton Broad on 
the 11th, and one there on March 10th.
