234 BRITISH BIRDS. [vol. x. 



which generally shoAvs that in some seasons, and in certain 

 localities they are much more plentiful than in others. 



White and variegated Blackbirds, being very conspicuous, 

 are quite useful aids to the understanding of migration, 

 and another thing which they teach, is the extent to which 

 individual birds take possession of a given territory. We have 

 had several pied Blackbirds at Keswick these last few years, 

 which have led to these remarks. One Blackbird f, with a 

 white patch on its back, was in the grounds for the greater 

 part of the winters of 1914, 1915 and 1916, and generally 

 very near the same place ; it seemed to arrive from the 

 north in September, but its date of departure was more 

 difficult to verify. Another f with a white head, which made 

 its appearance on March 20th, 1916, and was seen until 

 May 4th, then disappeared, but turned up again on September 

 13th and continued near the same spot with intervals until 

 December 3rd. These observations agree with some made 

 on a nearly white Blackbird t at Northrejops in 1876, 1877, 

 1878 and 1879, which was fortunate enough to live several 

 years before it was shot. 



A white Reed-Bunting was received by Mr. Saunders 

 from St. Olave's in September, and another in December bj' 

 Mr. Roberts from Rockland. 



On March 7th, Mr. E. Gunn received a white Wood- 

 Pigeon from Costessay, and on September 12th I saw one 

 at Keswick in the identical field, where there was one a few 

 years ago. 



A very good example | of the silver-grey variety or 

 " Bohemian " Pheasant which has been persistent in Norfolk 

 for a great many years, was killed on January 19th, by 

 Mr. P. B. Ficklin.. 



CiAssiriED Notes. 



Apart from the Skuas and the novel fact, to be mentioned 

 presently, of Cormorants having bred at Hockwold, in south- 

 west Norfolk, the year 1916 has been a blank year, the only 

 rarities being the adult Sabine's Gull seen by Mr. Patterson 

 in April, a White Stork in May, and a Little Bustard in 

 December. The absence of any record of the occurrence of 

 the White-tailed Eagle or Honey-Buzzard should be noted. 



The following notes, taken in conjunction with Mr. Arthur 

 Patterson's observations in The Zoologist (1916, pp. 369-377), 

 comprise everything which is worth putting down. 



The rainfall for the year was 31.67 (E. Knight). 



A dagger (t) indicates that the bird was examined by the 

 recorder.
