10 February Singers 



sometimes a marked decrease in the song of all 

 the birds of the garden when a spell of mild, dull 

 weather succeeds brilliant days with a sharp morn- 

 ing frost. Their spirits are quickened by the light, 

 but it is the softer weather which sets them actively 

 to nesting. Even the missel-thrush, which often 

 sings the more ardently and persistently the wilder 

 the March wind blows, is not induced to nest the 

 earlier by the turbulent weather which rouses it 

 to such a passion of song.
