VIGORSS WARBLER. 



Sylvia Vigomsii. 



PLATE XXX, Male. 



I KEGRET that I am unable to give any account of the habits of a 

 species which I have honoured with the name of a naturalist whose mei'its 

 are so well known to the learned world. The individual represented in the 

 plate I shot upwards of twenty years ago, and have never met with ano- 

 ther of its kind. It was in the month of May, on a small island of the 

 Perkioming Creek, forming part of my farm of Mill Grove, in the State 

 of Pennsylvania. The bird was flittering amongst grasses, uttering an 

 often repeated cheep. 



The plant on which it is represented is that on which it was perched 

 when I shot it, and is usually called Spider-ioort. It grows in damp and 

 shady places, as well as sometimes in barren lands, near the banks of 

 brooks.
