Rhoads and Pennock, Birds of Delazvare. IQ7 



(3) Marsh region, maritime and fresh, belonging to the Dela- 

 ware Basin. 



(4) Chesapeake Basin, comprising the bottom-lands of the 

 Choptank and Nanticoke Rivers. 



The list subjoined is far from complete and is based on notes 

 of a Preliminary List which was presented by the authors at the 

 annual meeting of the American Ornithologists' Union held in 

 Philadelphia in November, 1903. Much work remains to be done 

 in the State in this line, and it is attractive because so nearly 

 pioneer. The writers desire to acknowledge their obligations for 

 valued assistance in connection with the accompanying list, to the 

 late Walter D. Bush, Esq., of Wilmington, Del. ; Mr. E. W. Wool- 

 man and R. F. Miller of Philadelphia, Pa. ; and to Mr. Witmer 

 Stone of the Academy of Natural Sciences of Philadelphia, who 

 have so cordially assisted, by the loan of specimens, field notes, 

 and otherwise, in presenting a First List of the Birds of Delaware. 



Annotations here given on the occurrence, etc., of species have 

 been confined for the most part to such as are of unusual interest.
