Mississippi Valley, although it breeds locally near Baltimore, 

 Maryland. In winter it ranges as far south as Peru and Bolivia. 



20. Dendroica pensylvanica (Linn.). Chestnut-sided 

 Warbler. 



Mr. Loomis found this species breeding sparingly at Mt. Pin- 

 nacle' and abundantly on Caesar's Head, 1 while he has noted 

 it as a spring and fall migrant at Chester, where it occurs during 

 the last week of April and remains until the 15th of May. In 

 autumn it was observed from August 16 to October 19. 



The Chestnut-sided Warbler winters as far south as Panama. 



21. Dendroica castanea (Wils.). Bay-breasted Warbler. 

 The only well authenticated records of the occurrence of this 



warbler in the State were furnished by Mr. Loomis,' who procured 

 a specimen on May 14, 1887, and another on May 5, 1888, at 

 Chester. This species is evidently very rare in the South At- 

 lantic states. It breeds in northern Maine, New Hampshire, 

 and northward, while its winter range appears to be restricted 

 to Panama and Colombia. 



22. Dendroica dominica albilora Ridgw. Sycamore Warbler. 

 This is another western form which Mr. Loomis* has taken in 



the migrations at Chester, where it is common as a migrant, 

 while in Pickens county he procured a pair of adults and one 

 young bird on June 23, 1887, which proves that this subspecies 

 breeds locally and sparingly in the northwestern portion of the 

 State. Mr. Loomis did not, however, detect it at Caesar's Head. 

 This form breeds in the Mississippi Valley and winters south- 

 ward to Costa Rica. 



23. Oporornis agilis (Wils.). Connecticut Warbler. 



I have never seen this shy species in South Carolina, but Mr. 

 Loomis took a specimen at Chester on May 10, 1889. 5 The 

 capture of this bird in spring is noteworthy, as its route of migra- 

 tion at that season is to the westward of the Alleghanies. 



The Connecticut Warbler breeds, as far as is known, only in 

 Manitoba • and Minnesota, 7 and winters in northern South America .
