among underbrush. Seemingly it prefers conceal- 

 ment, if its actions afford any criteria. But later, 

 when the buds begin to burst and the leaves to 

 expand, it becomes less suspicious, and emerges 

 from its obscurity and charms us by the sociability 

 of its manners and the variety and loveliness of 

 its melodies.

 feeding it is both arboreal and terrestrial, but 

 chiefly the latter; never gleaning among the 

 topmost boughs of tall trees, but among low

 of the apple and cherry are often visited for the 

 insects which lurk in them; possibly, the authers

 Pangus caligiuosus, Harpalus pcnsyhanicus, H. 

 cornpar, Platyuus cupripcunis, Ptinus humeralis, 

 BostricJius piui, Formica sanguinea Luuibricus 

 tcrrestris and a species of Tulis. The above 

 insects constitute its food early in the season ; but

 lepidopterous types of articulate existences come
