ORNITHOLOGICAL REPORT FOR NORFOLK (1905). 

 By J. H. Gurney, F.Z.S. 



(Assisted by several Norfolk Naturalists.) 

 (Plate II.) 



The year 1905 produced two birds new to Norfolk, but it 

 was a year devoid of much visible migration, except for the 

 extended nocturnal movement of Aug. 25th, and that could hardly 

 be called visible. There was not enough windy and unsettled 

 weather to bring the movements of the birds under notice. The 

 Corvidce, which are always a criterion with us, have not been 

 noticed in any such great numbers as sometimes occur. The 

 chief autumn passage was that observed by Mr. F. Boyes in South 

 Lincolnshire on Oct. 9th and 10th, which evidently extended to 

 Norfolk, where it was recognized by the Rev. M. C. Bird. 



Vernal Migration. — The spring migration of 1905 into England 

 was studied by a Committee appointed by the British Ornitho- 

 logists' Club, which has published a valuable Report, in which, 

 referring to the east coast, it is pointed out (p. 58) that there is 

 evidence of a departure northwards (probably to Norway) of 

 Willow- Warblers from the coast of Norfolk at the end of April, 

 and of Sedge-Warblers (p. 69) and Redstarts in the beginning of 

 May. This I can readily believe, and should be inclined to add that 

 the destination of spring migrants, which pass through Norfolk 

 without halting, mainly depends on the wind, those which get a
