June 13, 1886, Mr. Jackson writes me: "A week ago to-day S. B. Ladd and myself 

 met H. G. Parker * * * and we put in the day collecting. The most im- 

 portant find of the day was a nest and five young birds of the black and white creeper. 

 They were nearly ready to leave the nest, and together we fully identified the parent 

 birds at close quarters. We also saw a female feeding a young bird from another nest, 

 that was just able to fly. This, I believe, adds another species to our county breeders, 

 does it not ? 



176. Protonotaria citrea (prothonotary warbler). Rare; migrant. (M. & B.) 



177. Helmi^ierus vermimrus (worm-eating warbler). Rare; summer resident; two 

 or three nests have been taken by Mr. T. H. Jackson, near West Chester; 1 saw a pair 

 of birds last of June, 1885, evidently with nest; nest on ground in woods. Mr. Jackson 

 and Mr. Ladd took several nests with eggs during the season of 1886.

 bushes; frequents vicinity of streams; eggs, 4-5. The nest of this bird usually contains 

 one or more eggs of the cow bunting. I have found a nest of this species that had been 

 remodeled l)y the parent birds twice, each time by building the sides higher and putting 

 in a new bottom to cover under an egg of the cow bunting.
