MALE AND FEMALE REED WARBLERS AT HOME.
The nest is a very beautiful structure, formed of long blades of dead grass, seed, branches of reeds, and bits of wool lined inside with fine dead grass and hair. It is cleverly suspended between two, three, four, or even as many as five reed stems at varying heights above the water. I have, however, on several occasions seen it in willow and alder bushes at some distance from that element, and it has even been found in a lilac bush in such a very unlikely neighbourhood as Hampstead.
YOUNG REED WARBLER
The structure is very deep for the size of the builder, but this peculiarity of its architecture serves a very useful purpose, for when the reeds to which it is attached are violently swayed to and fro by strong gusts of wind, it prevents the eggs from rolling out and away to certain destruction.
The eggs, numbering from four to six, are of a dull greenish-white or greyish-green ground colour, spotted and blotched with darker greyish-green and light brown.
The male helps the female not only in the work of feeding the chicks, but in brooding, and it is a very pretty sight to see them exchanging places on the nest.
The song of this species somewhat resembles that of the Sedge Warbler in being full of chatter, but is not so loud or harsh, and is delivered, as a rule, whilst the singer is hiding amongst reeds. It imitates the note of the Starling, Wagtail, Swallow, and other birds, but is vastly inferior to the Marsh Warbler both as a musician and a mimic. I have heard it at its best during a calm summer evening on the Norfolk Broads, where it sings far into the night and early in the morning, excepting during windy weather, which seems to be greatly disliked by all feathered inhabitants of reed beds. The following extracts from one of my old diaries kept during a stay on Hickling Broad illustrate rather graphically the influence of wind upon the vocal activities of birds:
May 27.—“Windy, dark night; not a bird of any kind to be heard.”
May 28.—“Fine calm night. Reed, Sedge, and Grasshopper Warblers, Snipe, Water Rail, Coot, Moorhen, Peewit, and other birds all singing and calling until one o’clock in the morning.”
