The specimens in the case, both old and young, 

 were obtained near Heigham Sounds in Norfolk, in 

 July, 1871. 



GREY PLOVER (AUTUMN). 

 Case 22. 



This case shows the immature birds on their 

 first arrival in this country in the autumn, and also 

 the winter plumage of the adult. 



The specimens were obtained on Breydon 

 mudflats, in the autumn of 1872. 



GEASSHOPPER WARBLER. 

 Case 23. 



Though frequently found in the neighbourhood 

 of water, this Warbler is by no means so aquatic 

 in its habits as the more common Reed and Sedge 

 Warblers. Several pairs breed round most of the 

 broads in the east of Norfolk, and I have also 

 discovered their nests in hayfields and bramble- 

 covered banks in the more southern counties. 



When shooting in the Nook, at Rye, in Sussex, 

 early one morning in May, 1858, I found that the 

 samphire and other small weeds that grow on the 

 mudbanks completely swarmed with Grasshopper 

 Warblers. They had evidently only just landed, 

 and were on the point of making their way inland. 

 There must have been several hundreds in a small 

 patch of weed of a dozen or twenty acres. There 

 were probably some other small birds of passage 

 among them, but two shots which I fired into the 

 weeds produced about half a dozen, all of which 

 were of this species. 



I am unable to account for so many being 

 found together, as I have noticed that our spring 

 migrants arrive, for the most part, singly or in
