that a skunk or other depredator had destroyed the whole 

 family. 



The Oven-bird feeds principally upon small insects and 

 smooth caterpillars, which it obtains usually on the ground, 

 among the fallen leaves : when berries are in season, it feeds 

 occasionally upon them ; and it seems particularly fond of 

 small spiders, with which I have sometimes found its stom- 

 ach filled. About the 12th or loth of September, after the 

 young birds have become capable of providing for them- 

 selves, the whole family leave for the South.

This bird is not very uncommon in New England in the 

 spring and fall migrations (arriving about the 1st of May, 

 and departing about the last week in September) ; and I 

 have sometimes seen it in summer in Massachusetts. It 

 undoubtedly breeds in the three northern of these States, 

 and probably in them all. In its habits, it much resembles 

 the preceding species ; but it is seldom found in any but a 

 wet locality. 



Wilson says, " This bird is remarkable for its partiality 

 to brooks, rivers, shores, ponds, and streams of water;
