Cooke — Birds of the Washington Region. 3 



species which occur regularly; (3) Rare, Irregular, or Accidental 

 Visitants, those which are stragglers or occur only in small 

 numbers; (4) Hypothetical Species, those concerning which 

 the data is insufficient to allow their inclusion in any other 

 division. For convenience, the table of migration dates of 

 regular migrants is placed at the end of the present paper. 



As far as possible the authorities for all records are given. 

 Several years ago, Dr. Charles W. Richmond kindly loaned to 

 the Biological Survey his manuscript notes on the birds of this 

 vicinity which were then copied for the dates only. As the 

 original notes are not just at present available, in many cases it 

 is impossible to tell which are from his own observations, and 

 which from other sources which he considered authentic. In 

 such instances, the records are quoted as "Richmond MS." 



I desire to express here my gratitude to those persons, many 

 of whose names appear as authorities for records, whose reports 

 on the birds about Washington have made my work possible. 

 I am especially indebted to Dr. Harry C. Oberholser and Mr. 

 Francis Harper for much valuable advice and assistance.
