The following TABLES are divided into two Sedions. The firfl: fe6:ion contains an enumeration of the Spring 
and Summer Birds of Paffage. All thefe, with the exception of a very few, which may be called Resident Birds, 
come from the fouth. The greater part of them are known to build and breed in Pennfylvania. At the clofe of 
the fummer and in the autumn, they retire again to the fouth, and vifit us in the Spring. 
The fecond feftion is devoted to the Autumnal and Winter Birds of Paffage. Thefe paffengers may be di¬ 
vided into two claffes : viz. I. The Spring and Summer Birds of Paffage, which are nov/ on their return to the 
fouth. In ftridt propriety, thefe ought not to be confidered as Autumnal and Winter Paffengers: for they leave us 
in cold weather, either becaufe they are incapable of fupporting the feverity of the winter-feafon, or becaufe they 
cannot, during this feafon, procure a fufficiency of their proper and favourite food. Perhaps, for both thefe caufes. 
II. The fecond clafs comprehends the real Autumnal and Winter Birds of Paffage. Thefe, compared with the Spring 
and Summer Birds of Paffage, are very few in number. They all come from the north, and either winter with us 
or in the fouthern ftates. In the fpring (frequently very early in the fpring), they retire northerly, where they 
build, breed, and rear their young.
