through the summer, mostly immature, with a few adult non-breeders. Blotched individuals, assuming the mantle, not unfrequently seen. 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 occasionally 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 formerly.
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. 20th, "one game-dealer had thirty Skuas at one
