126 THE BIRDS OF ^NORTHAMPTONSHIRE 



late, or perhaps later, than any of our summer visitors, 

 as I sometimes notice one or more of these little 

 birds haunting our thick fences at the end of Sep- 

 tember, and occasionally in October. The song of 

 this species is, to my ear, much more agreeable than 

 that of the Common Whitethroat, and is continued 

 throughout the month of August. I believe this 

 to be the bird, or one of the birds, to which our 

 country people give the name of "Hay-bird" or 

 " Hay-tit " ; but this I know is a somewhat vague 

 appellation, and is applied to several of our summer

 I have found one at a height of at least five feet 

 therefrom : a thick bramble bush is often chosen ; 

 and a very favourite locality is the thick young thorns

 strips of ground adjoining some of our old untrimmed 

 fences, the said thorns growing apart from the fence 

 in low, thick clusters, often interspersed with nettles 

 and other summer-growth. The eggs are very 

 peculiar, and can hardly be mistaken for those of any

 blotches, and giving the eg^ the appearance of having 

 been touched with a hot needle or with caustic. I 

 find it always somewhat difficult to describe varie- 

 gated eggs, as the colours, shades, spots, blotches, 

 speckles, and streaks are often so mingled as almost to 

 defy accurate description, and no written account of an
