Whilst living in a house-boat on the Norfolk Broads, studying Nature, I have had many excellent opportunities of observing the habits of this interesting bird, and have often heard it singing at night when the stars were reflected on the dark, still water around me and not a breath of wind stirred the balmy air. The best time of all, however, to hear a Grasshopper Warbler in full song is at sunrise. When the first gleam of rosy light tints the dead brown reeds with coppery red and dewdrops twinkle on every blade of grass, the bird mounts to the topmost twig of some stunted alder bush or blade of sedge, and standing quite still, with widely opened mouth and quivering body, pours forth his strange song in one incessant stream. Whilst the music lasts the head is turned from side to side, and it is this action which appears to give it a ventriloquial effect. [Illustration: GRASSHOPPER WARBLER ON NEST.] If the bird be disturbed it instantly ceases to sing, and dropping stealthily into the undergrowth waits in silence until the danger has passed; then it recommences. When the singer is not seen, the exact locality from which the sounds are proceeding is very difficult to discover. This arises from two facts--the shrillness of the tones, as in the case of a mouse squeaking when running about amongst grass, and the movements of the head already mentioned. The sound, although somewhat similar to that made by a grasshopper, is much more sustained, and always appears to me far more machine-like. In fact, it is known in some parts of the country as the “Reeler,” in recognition of the fact that its notes resemble the sounds made by a reel used during the last century by hand-spinners of wool. Once the bird has been heard, its song can never be forgotten or mistaken for that of any other British Bird. Its call note is a sharp _tic, tic_. The Grasshopper Warbler builds upon the ground, or very near to it. Its nest is well hidden, and is composed of dead grass and bits of moss, with an inner lining of fine, fibrous grass. The eggs, numbering from four to seven, are of a pale rosy-white ground colour, very thickly spotted and speckled, especially at the larger end, with reddish-brown. The bird approaches and leaves its nest in the most mouse-like manner. I have frequently taken it for one running through the rough matted grass, even when I knew the exact whereabouts of its home which I was approaching.
