The abbreviations used in the first column of each county list classify 

 the birds under the following heads. Residents (res) are those species 

 which are found at all seasons of the year and breed within the county. 

 Summer residents (sr) spend only the warmer part of the year in the county, 

 coming from the south in the spring, returning to the south to pass the winter. 

 Transient visitants (tv) are species which merely pass through the county 

 in the spring or fall, or both, on the way to their breeding grounds. Winter 

 visitants (wv) are those which come from their homes in the north to pass 

 the winter with us. Summer visitants (sv) are species which breed farther 

 south but visit us in considerable numbers during the summer after the breed- 

 ing season is over. Accidental visitants (av) are species which live so far 

 from our borders, and are found here so rarely, that their occurrence may 

 be regarded as accidental. 



In the second column the relative abundance of species is indicated 

 by the terms Abundant (ab), applied to such birds as the Robin and Song 

 sparrow, which are very common in the locality. Common (c) indicating 

 a less degree of abundance. Fairly common (fc) birds are such as are found 

 in limited numbers at the proper place and season, like the Scarlet tanager, 

 or Migrant shrike in western New York. Uncommon (unc) birds are such as 

 can not be called rare and yet are of unusual occurrence. Birds of Occasional 

 occurrence (oc) are those which are not observed each season but appear at 

 intervals of a few years. A rare bird is one which has been recorded only 

 a few times and yet can not be regarded as accidental. We have also 

 found it convenient in these tables to use such expressions as local, referring
