THIS familiar species is a summer inhabitant of New 

 England : it arrives from the South about the second 

 week in May. Its habits are not well known, as it is not a 

 very common species, and it inhabits the most secluded spots 

 in the deep woods ; but its song is well known to all, a^ are 

 its nocturnal wanderings in search for insect food. This 

 bird, as also the Night-hawk, is, to the farmer, one of the 

 most valuable among the feathered tribes : its food consists 

 almost entirely of night-flying Lepidoptera, and the number 

 of these insects destroyed is immense.
