330 ORNITHOLOGY AND OOLOGY. *fc| 



The habits of this bird are pretty well known. 5| is a 

 very fine songster, and is hardly excelled by Zjty of our 

 other species; its notes being uttered, not only through 

 day, but also during the night, as I have heard on te- 

 occasions. The song is difficult of description : it TjTT 

 sweet warble, with various emphatic passages, and some* 

 times a plaintive strain, exceedingly tender and affecting. ^ 



The Grosbeak feeds upon the seeds of the birches and 

 alders, which it obtains very expertly. It also is very fond 

 of various berries and buds, and it occasionally searches 

 among the fallen leaves for insects and worms. 



After the young birds have become capable of providing 

 for themselves, the whole family sometimes visit the orchards 

 and gardens, where they eat a few berries and currants. 

 By the middle of September, they proceed leisurely on their 

 southern migration.
