70 GRASSHOPPER WARBLER. 
Its stridulous note, from whence its name, strikingly 
resembles the chirruping sound of the large green grasshopper, 
or rather locust, to be heard so loud and shrill in the southern 
counties in the fine summer evenings. It is often continued, 
particularly in the earlier portion of the year, for two or 
three minutes without cessation, and may be heard at a 
considerable distance. Farther on in the season it is most 
heard at night, but is not continued in general later than 
July or August. The note is faint at its first commencement, 
but it ‘vires acquirit eundo,’ and gradually becomes louder 
and louder, till it is audible at a considerable distance. It 
is suspended on the slightest alarm, and the bird vanishes 
into its cover, from whence, when the danger has passed, it 
emerges again to ufter its chirping cry from another bush. 
At times they utter it in the air, hovering over the bush 
which contains their nest. It has been suggested that the 
object of this note may be to decoy the large grasshoppers, 
who may mistake 16 for the call of their own species. In 
the earlier part of the day it sometimes sings perched. on- 
the top of a twig, and shivering its wings. ‘Nothing,’ adds 
Gilbert White, ‘can be more amusing than the whisper of 
this little bird, which seems to be close by, though at a 
hundred yards distance, and when close to your ear is scarce 
any louder than when a great way off.’ This ventriloquistic 
power is certainly very remarkable, but in many cases the ~ 
sound has, in all probability, proceeded from a Grasshopper 
Warbler of the insect species. 
The nest, of a cup shape, is formed in a rather firm manner 
of grass, with sometimes a little moss, lined with finer portions 
of the same. It is difficult to find, owing to the careful 
habits of the bird, and is placed on the ground, and has 
been met with at the foot of a small bush by the road side; 
it is completely hidden in the middle of some large tuft, 
through which there is no entrance but such as the bird 
threads for herself, creeping along like a mouse to and into it. 
The eggs are from five or six to seven in number, of a 
pale reddish white colour, freckled all over with specks of 
darker red; they seldom vary much. 
The young soon quit the nest on being disturbed, trusting 
by imstinct to their habitual powers of concealment.
