 Americana, Spilosoma Virginica, S. acrcra, and

The note of the Long-billed Marsh Wren is a 

 harsh, grating cry, lacking in power and harmony, 

 and resembling more nearly the sounds of an 

 insect than those of a bird. 



It is an early, autumnal migrant, usually retir- 

 ing to its winter quarters in the beginning of 

 September, long anterior to the growing scarcity 

 of food-stuffs. 



The eggs of this species range from six to nine 

 in number, are oval in shape, but occasionally 

 spheroidal. They are thickly marked with blotches 

 of a deep chocolate-brown, so as to present an 

 almost uniform appearance. The average length 

 is .65 of an inch, and breadth ,50.
