EXPLANATION. 



The nomenclature used is that adopted by the American Ornitholo- 

 gists' Union. 



The first number given before each species is the serial number for 

 this list; the second number, enclosed in parenthesis, is that by which 

 it is indicated in the A. 0. U. Check List. 



No species is included in this list unless it is known to have been 

 reported, upon good authority, to have been observed within the State, 

 and no species has been reported as having bred within the State un- 

 less it is known, according to the same authority, to have done so. 



All measurements are given in inches and hundredths of an inch.
