320 PHILOMELA. NIGHTINGALE. 



to the fifth, the third longest, the fourth scarcely shorter. Tail 

 rather long, straight, even, or slightly rounded, of twelve rather 

 broad feathers. 



The Nightingales differ from the Warblers chiefly in being of 

 a more slender form, and in having the bill, tarsi, and tail more 

 elongated. They are very intimately allied to the Turdinge 

 by means of some of the smaller Thrushes, especially Turdus 

 Wilsoni and Turdus minor, which in form and colour, with 

 the exception of the spots on the breast, are very similar to the 

 common Nightingale. They are insectivorous, migratory in 

 temperate and cold countries, plainly coloured, and remarkable 

 for their song, which excels that of the other Sylvianae. One 

 species occurs in England, but has not hitherto been with cer- 

 tainty observed in Scotland.
