VOL X.] ORNITHOLOGICAL NOTES FOR 1916. 241 



Gargane Y ( A . querquedtUa ) . 



Only one pair reported this year on our principal Broad, 

 which is not good. Last year the keeper knew of two pairs, 

 but they certainly are not so common on the eastern side 

 of the county, as the}?" used to be, yet this is not from per- 

 secution, because they are protected. 



Smew {Mergus albellus). 



On January 1st a female was brought into Norwich (E. T. 

 Roberts), and on the 6th Dr. Long saw an adult male on 

 Langmere. Norfolk has not had a Smew year since the 

 hard winter of 1890-1, when the frost lasted fifty-one days, 

 and many Swans and other wildfowl were shot as well. 



Cormorant {Phalacrocorax carho) . 



At the end of August IVIr. H. E. Upcher discovered a pair 

 of Cormorants nesting in Hockwold fen near Brandon, at a 

 spot about twenty-two miles from the sea (c/. antea, p. 120), 

 very near where his father and I saw the Great Bustard in 

 1876. This is the second occasion on which Cormorants 

 have bred of recent years {cf. Vol. VIIL, p. 130), and is 

 indicative of a return to old habits. 



Fulmar Petrel (Fulmar us g. glacialis). 



Mr. Richards picked up an adult on the sand on September 

 21st. In this species the trachea is divided by a septum, 

 which gives it the appearance of a double windpipe. 



Black-necked Grebe {Colymbus n. nigricollis). 



On April 27th, Mr. Vincent saw a Black-necked Grebe at 

 Hickling, where it remained until May 14th. It probably 

 did not find a mate, but there is good reason for supposing 

 that on some former occasions this species has bred with. us. 

 The last which were reported on this Broad were a pair in 

 May 1911. In 1892 there was one on Rocldand Broad as 

 late as July 28th {Zoologist, 1892, p. 358), but the supposition 

 that it had young ones {i.e., p. 400) was probably without 

 foundation. 



Black-throated Diver {Gavia arctica). 



Mr. E. T. Roberts announced a Black-throated Diver "f 

 on the small Broad at Rockland on January 19th. On 

 February 22nd there was one "j" on Selbrigge pond, which 

 seemed uneasy as if just arrived ; the woodman drove it to 

 where I was hidden, but it evidently suspected danger. The 

 next dsij was very coarse with blizzards of snow, which
