 ave. 9 yrs. Aug. 23. 



214. Oporornis agilis Connecticut Warbler. Rare 

 transient. Dr. Montgomery collected specimens 

 Sept. 20 and 28, 1889, and saw another Sept. 25, 

 all in West Goshen ; and I took single birds on Sept. 

 II, 1893 and Oct. 7, 1897 (Nos. 423 and 636, coll. 

 F. L. B.). There are no spring records. 



Fall arrival — Sept. 19 (1893) — Oct. 7 (1897); 

 ave. 5 records Sept. 26. 



215. Oporornis Philadelphia. Mourning Warb- 

 ler. Rare transient. Michener gave it as a summer 

 resident, extremely rare. Four specimens have been 

 taken by Josiah Hoopes and Witmer Stone (Bds. 

 E. Pa. and N. J., 139) ; and according to Warren, 

 Harry Garrett of Willistown has also taken speci- 

 mens. Pennock states that on June 19, i886, a 

 female, which had been found a few days before, 

 was brought to him, and a male was seen in the same 

 vicinity about June 12. The inference is that the 

 pair would have nested in the neighborhood (Ool., 

 iii, 46).
