INSESSORES. 63 



Kingsbury, and succeeded in shooting three of the 

 birds, two males and one female, and very kindly 

 gave me one of the males. Mr. Bond also told me 

 in the spring of 1843, that he had again seen one 

 example near Kingsbury Keservoir." 



In the spring of 1859, Mr. Spencer obtained two 

 specimens at the same place, and another pair was 

 observed there in the spring of 1862. I have noticed 

 this species at Harrow Weald, in May. 



Mr. William Borrer, of Cowfold, Sussex, has so 

 clearly pointed out the leading features by which 

 this bird may be distinguished from the Pied Wag- 

 tail, and the two species are so frequently con- 

 founded, that it may not be out of place to quote 

 his words here. In the White Wagtail, he says, 

 " the head is covered with a distinct hood of pure 

 black, perfectly defined, and not mixing either with 

 the grey of the back, or with the white of the fore- 

 head ; the white on the cheeks and sides of the 

 neck completely separates the black of the head 

 from that of the throat and breast, there being no 

 black before the shoulders ; the sides also are much 

 lighter, and the tail somewhat longer. In the female 

 there is no mixture of black on the back and nape, 

 which there is in all the females of the Pied Wag- 

 tail that I have examined." 



GREY WAGTAIL, Motacilla boarula. An uncertain 

 winter visitant ; in some years tolerably numerous, 

 in others scarce. I have seen it at Kingsbury
