similar form, but invariably, we believe, lined more or less 

 with feathers. The eggs of the "Wood Wren, six or seven 

 in number, are white, with purplish-red spots. 



WILLOW WARBLER, OR WILLOW WREN. Sylvia trockilus. 

 This is an abundant species, and its nest, also built on 

 the ground, is concealed with amazing skill, and probably 

 seldom found except by the flight of the bird to or from it. 

 On some open furze-covered lands in the neighbourhood of 

 our dwelling many of these nests were found, at the foot of 

 furze or other bushes, during the last summer. The nest 

 is domed, like that of the preceding species, but differs from 

 it, as already stated, in being lined with feathers. The eggs 

 are six or seven in number, white, spotted with pale-red, by 

 by which they may be distinguished from those of the Chiff- 

 chaff, which are spotted with dark-purple. (PL IX. fig. 58.) 



THE CHIFF-CHAFF WARBLER. Sylvia rufa. We often 

 hear this little bird with its characteristic and cheerful, but 

 somewhat monotonous, note, yet its nest and eggs appear 

 to be seldom found, certainly not nearly so frequently in 

 this locality as those of the Willow Wren. The nest is not 

 placed invariably on the ground, but occasionally a little 

 above it, and is globular and lined with feathers, having a 

 small aperture for the entrance : the eggs, usually seven in 

 number, are white, with purple-red spots. (PL IX. fig. 57.)
