GRASSHOPPER-WAEBLER.— DARTFORD WARBLER. 69 



to ascertain from whence the sound proceeds, which may 

 perhaps be accounted for by the habit Avhich the bird has 

 while uttering its note of turning its head in all directions. 

 I once watched a Grasshopper- Warbler from a seat in a 

 summerhouse, not more than eight or ten yards distant from 

 it, and was surprised to see that, while pouring forth its 

 note, its mouth appeared to be wide open, and I could not 

 detect the slightest movement of either mandible, but it 

 might have been too rapid for my eye to follow. During all 

 this time it kept up a constant quivering with its wings. 



DARTFORD WARBLER. 



Melizojihilus undatus.

Mr. Knox mentions a nest having been taken on the 

 3rd of May, ISI^i, on the '' Broyle," near Chichester. 



In the 'Zoologist' (p. 3113) Mr. EUman gives an in- 

 teresting account of the manners of the Dartford Warbler, 

 and mentions a female shot by him on the 12tli of October, 

 and a male, on the 7th of November, 1851. Mr. Wilson 

 states, in the same journal (p. 6606), that in the neighbour- 

 hood of Worthing, a male and female were taken in the 

 summer of 1853, a male in 1857, and young in 1858. At
