through the summer, mostly immature, with a few adult non- 

 breeders. Blotched individuals, assuming the mantle, not unfre- 

 quentiyseen. Birds of the year {local, "Grey" Gulls) numerous 

 during herring fishing and in winter along the shore, at which time 

 there is in the early morning a movement southward, and again at 

 eventide, northwards. 



L. glaucus. Glaucous Gull. — N. U. A regular *' hard- 

 weather" species. Numbers brought in by fishing-smacks, Jan. 

 1881 ; I know of twenty-seven offered for sale in one lot, of which 

 seven were fine adult birds. Several have been killed in the 

 neighbourhood, odd birds being met with in ordinary winters. 

 Example killed at Caister, Feb. 1899. 



L. leucopterus. Iceland Gull. — R. An example killed in 

 Nov. 1852 (B. of S.). A second obtained at Caister in Nov. 

 1874. Two others at Yarmouth and Scratby, respectively, 

 Dec. 6th and Dec. 28th, 1892. I saw, and crept to within a few 

 yards of, one near Breydon walls on Jan. 14th, 1899 ; it was 

 subsequently shot. On May 3rd, 1899, I observed a white Gull, 

 which I believed at the time to belong to this species. It remained 

 with other Gulls two or three days, and was unmolested ; but was 

 afterwards shot, and identified as a variety of Larus canus. 



Rissa tridactyla. Kittiwake Gull. — F. C. A peculiarly marine 

 species, spending much time far out at sea. Is well known to 

 the herring fishers. It inshores in stormy weather, and appears 

 sometimes to perish in heavy gales, after which I have occasion- 

 ally picked up several. On Feb. 16th, 1890, I found no fewer 

 than thirty, with sixteen dead Razorbills at intervals, in a walk 

 along the beach. It may be identified at sea by its erratic flight. 

 Is not so common locally as formerl}'. 



Stercorarius catarrhactes. Great Skua. — R. R. A rare bird 

 on our coasts. Messrs. Paget state that four were shot in the 

 Roads, Oct. 7th, 1827. Mr. Stevenson enumerates several for 

 Yarmouth (B. of N. vol. iii. p. 346). One at Yarmouth, 

 Oct. 3rd, 1881. 



S. 'pomatorhinus. Pomatorhine Skua. — R. R. This species 

 is the most frequent of the Skuas on the east coast of Norfolk. 

 Several have been recorded during the century during gales, 

 chiefly in October. Many were met with in 1874 ; after a heavy 

 gale on Oct. 2Uth, " one game-dealer had thirty Skuas at one
