Tue following list embraces the species of birds procured by 
7, and with a few exceptions within five 
miles of the ti Carlisle, during a period of four years. 
ed whilst living in our fields, woods and mountains, by our run- 
ing streams and marshes, and in no instance are apy placed in 
the list upon the authority of other persons. Probably but few 
remain to be found in the county, as every part of it has been 
searched, and if any have escaped observation, it is likely they 
are species belonging to the Sylvicolide or Fringillide, which 
from their habits, small size, and generic features of resemblance, 
may have been confounded with others which are well known. 
Our object in giving this list is to show at one view the season 
of migration, the comparative variety or abundance, &c. of the 
birds found in the interior of Pennsylvania. As might readily 
be imagined, land-birds largely predominate, there being no large 
tivers in Cumberland County, if we except the Susquehanna, 
which forms the eastern boundary, and which at this place flows ” 
rapidly over a rocky bed, serving only asa resting place for a few — 
aquatic species when forced to alight whilst migrating, from bad 
weather or other causes, and affording no mud-flats or sand-bars, 
favorite resorts of the waders. Residing, as we do, eighteen 
miles from the Susquehanna, possibly some species pursue that 
tiver’s course in travelling north or south which may have escap- 
ed our observation, and would have been noticed had we been 
living on its banks. 
Much has been done towards elucidating the habits of our birds 
by Wilson, Audubon, and our other writers on the subject, and 
When the vastness of their field of observation is taken into con- 
sideration, no one will be inclined to deny that their success has 
fn very great. But the greatness of their undertaking, the 
Whole of the United States and parts of Texas having been ex- 
Plored by them, has prevented minute attention to the ornithology
