233. Sitta carolinensis carolinensis White-breast- 

 ed Nuthatch, "sapsucker," "woodpecker." Toler- 

 able common resident, less frequent in the nesting 

 season. Dr. W. E. Rotzell and the writer took 

 a set of nine eggs near Berwyn, Apr. 27, 1889.

235. Beeolophus bicolor Tufted Titmouse, "blue- 

 bird," "little jay," "tit." Rare resident, noticed more 

 often during the spring migrations, especially Feb- 

 ruary, March and April. Wilson reports it a win- 

 ter or spring visitant in Highland Twp. ; Hunt has 

 dates for every month in the year in Honeybrook 

 and Nantmeal Twps. Jackson informs me that 

 it undoubtedly breeds along the Brandywine below 

 Downingtown, but he has never actually located its 

 nest. Pennock, apparently, has found it breeding 

 but gives no dates ; Thomas found a nest at Kennett 

 Square in the summer of 1908, date not recorded.

 dee, "chickadee-dee," "sapsucker," "tit," "titmouse," 

 "tomtit." Tolerable common winter visitant. All
