FEMALE WOOD WREN ABOUT TO ENTER NEST.
Its nest is built on the ground amongst thick herbage, is oval in shape, and domed. The outside consists of dry grass, dead leaves, and moss, with an inner lining of fine dead grass and horsehair. Although in general appearance the structure is almost exactly like those of the Willow Wren and Chiffchaff, it may always be distinguished with certainty from them by the absence of feathers.
The eggs, numbering five or six, are white, thickly spotted all over with dark purplish-brown and violet-grey.
The song, although short, is clear, loud, sweet, oft repeated, and sounds something like sit-sit-sit-sit-sit-see-eeeeeze. Each of the opening notes of the song is uttered more rapidly than that which preceded it, until they develop into a kind of trill, rising in pitch all the time, and finally end in a long, shaky, thin one. The melody is accompanied by rapid vibrations of the wings and tail, as if the loud voice shook the body of the wee singer.
The call note is a plaintive twee or tway tway, frequently used as a kind of alternative to the song described above.
Although such a small bird, the Wood Wren is very courageous at the nest. The individual figured in our illustration repeatedly attacked my hand with bill and wings when I attempted to disturb her in her maternal duties. She was very angry with me when the photograph was secured, and incidentally it shows the great length of wing in this species.
This Warbler is a late arrival upon our shores, coming about the end of April and departing again in September. It lives entirely upon insects.
