This swallow is very numerous on the low marshes on the southern shores of Long island. 

 They are slaughtered by thousands and sent to market, and are much esteemed by gour- 

 mands as some small species of snipe. It feeds partly on insects and partly on berries, par- 

 ticularly the fruit of the Myrica cerifera, or Wax-berry, on which it becomes exceedingly 

 fat. It builds in hollow trees, and also occupies boxes in the neighborhood of dwellings. 

 Eggs from 4 to 6, pure white. It ranges from the Gulf of Mexico to the 60th parallel of north 

 latitude. A few, according to Audubon, winter in the neighborhood of New-Orleans. It 

 appears in this State about the middle of April, and leaves us on its southern migration in 

 the early part of September. Boie has made it the type of his genus Chelidon. It is 

 peculiar to America.
