THE GOLD-CREST 33 



a practised observer, they are likely to be mistaken for one another. 

 In song, however, they differ materially, and as this is begun early, 

 and continued tiU very late in the season, it affords ready means 

 of discriminating the species. The Wood- warbler, or Wood-wren 

 as it is now called, arrives in England towards the end of April, 

 and betakes itself to woodland districts, where it spends the greater 

 portion of its time among the upper branches of lofty trees, constantly 

 moving from place to place with rapid irregular flight, and fre- 

 quently repeating its short and peculiar song. It feeds exclusively 

 on insects, which it occasionally catches on the wing. Its song is 

 difficult to describe. The name by which it is popularly known 

 in some parts of France, TouUe, is derived from the syllable 

 ' tweet ' , which, rapidly and continuously repeated many times, 

 constitutes its song. These notes are uttered in a sweet tone, and 

 with a tremulous accent, and are unlike those of any other bird. 

 GUbert White, who appears to have been the first who noticed the 

 bird, describes it as " joyous, easy, and laughing". The last notes 

 of its strain are accompanied by a quivering of the wings and tail, 

 which accounts for their tremulous sound. 



The Wood-warbler is much less frequent than either the WiUow- 

 warbler or Chiff-chaff, and on a close inspection may be distin- 

 guished by its superior size, by the pure white of its under tail- 

 coverts, and by the bright yellow line above the eye. The nest 

 is composed of grass, ferns, and moss, and lined with fine grass and 

 hair ; it is covered with a dome, an entrance being left sufficiently 

 large to allow its contents to be seen, and is placed on the ground, 

 in or near a wood, among thick herbage, or against the stump of 

 a tree. The eggs are from five to seven in number, almost round, 

 and so thickly spotted with purple-brown that the ground is almost 

 invisible.
