187. Vireo solitarius. Blue-headed Vireo. 



A transient visitant, not common. In 1900 it was detected only 

 in the fall migration. One was taken in shrubbery along the board- 

 walk September 27, and another was seen in a similar situation 

 October 1. Mr. Simpson reports having met with it on April 26, 

 1902. 



[ Vireo noveboracensis. White-eyed Vireo. 



This vireo is exceedingly rare throughout western Pennsylvania. The writer has 

 never met with it anywhere in this section, but it is as apt to occur at Erie as else- 

 where in the region. It is said to be fairly common at Jefferson, Ashtabula County, 

 Ohio (Jones, Birds of Ohio, 1903, 171).] 



188. Mniotilta varia. Black and White Warbler. 



Although not actually observed during the breeding season proper, 

 there can be no doubt that this species is a summer resident, not, 

 however, very common. In 1900 it was noted first on April 28, and 

 the last was recorded September 21. Mr. Bacon has taken specimens 

 on May 1, 1892 and 1894, and Mr. Simpson shot one April 26, 1902. 



[Helminthophila pinus. Blue- winged Yellow Warbler. 



Dr. Warren speaks of having met with this warbler in summer in Erie County 

 {Birds of Pennsylvania, 1890, 276), but the exact locality is not stated, and the 

 record cannot therefore be used. Moreover, in the absence of specimens it would 

 seem as if the record were open to doubt. This is one of the very rarest warblers in 

 western Pennsylvania, and that it should breed so far north as Erie County seems 

 highly improbable. 



Helminthophila chrysoptera. Blue Golden-winged Warbler. 



It was surprising not to meet with this warbler at Erie, in view of its comparative 

 abundance in the western part of the State in general. Doubtless future observations 

 will discover its presence. ] 



189. Helminthophila rubricapilla. Nashville Warbler. 



A transient visitant, possibly not uncommon, although it has been 

 definitely recorded but twice. Mr. Bacon secured two specimens 

 May 9, 1892, and Mr. Simpson shot one along the board-walk Sep- 

 tember 27, 1902. 



190. Helminthophila celata. Orange-crowned Warbler. 



One of the surprises connected with the work in this locality during 

 1900 was the discovery of this species — not an isolated record, as is 

 usually the case in the Eastern United States, but several occurrences, 

 seeming to indicate that it is a regular although uncommon fall migrant. 

 It was first brought to light by Mr. Simpson, who secured a specimen 

 near Big Pond on September 15. On October 6 one was observed
