As we have remarked in a previous notice, these yearly 

 Reports (of which this is the eighth) become more and 

 more valuable by continuity of observation on the same 

 lines. But in addition to this the present Report is even 

 fuller than previous ones, and this says much for the 

 keenness of observers, as well as for the untiring labours 

 of the Committee whose task it is to collate and report on 

 the mass of observations. 



March, 1912, was exceptionally mild, and the weather 

 during this month as well as in April and May was favour- 

 able to migration, " consequently . . . individuals of many 

 species arrived in various parts of the country on unusually 

 early dates." The weather in the autumn of 1911 was also 

 so favourable to the birds that they were not "held up," 

 and consequently moved away so gradually as to make 

 observation difficult. The winter of 1911-12 was chiefly 

 remarkable for the '-'invasion" of Little Auks, which was 

 well recorded in our pages, and of which a condensed report 

 is given. Other observations of special interest which have 

 not been previously referred to may here be mentioned. 



The Lesser Whitethroat {Sylvia c. curruca) is recorded 

 from Cumberland, Northumberland, and Anglesey in May, 

 1912. A considerable oversea immigration of Stonechats 

 occurred at the South Foreland Light on February 24th- 

 25th, while fourteen were killed at the Morecambe Bay 

 Light- vessel on May 5th-6th. A Nutcracker {Nucifraga 

 caryocatactes ? subsp.) is recorded from Broome (Kent), 

 about October 9th, 1911, at the time when several were 

 reported (c/. B.B., Vol. V.). A Golden Oriole {Oriolus o. 

 oriolus) was seen near Scarborough (Yorks.) on July 9th, 

 1911, and another during the summer and until August 28th, 

 at Cusop (Hereford). A Red Grouse {Lagopus I. scoticus) 

 was killed on Bardsey Island (Carnarvon) on April 

 20th.— H.F.W.
