YOUNG, Birds of the Coal Regions of Pennsylvania. I o"t 



or four Bank, or Rough-winged Swallows on the Black Creek near Penn 

 Haven Junction. I cannot say which species they were, however. I also 

 saw them at Nescopeck, but failed to procure specimens there either. 



44. Ampelis cedrorum. Cedarbird.— Very common throughout the 

 region. I saw a flock of fifty or sixty of this species at Delano, on June 1, 

 and observed them flocking again early in August. 



45. Vireo olivaceus. Red-eyed Vireo. — Generally common. 



46. Vireo gilvus. Warbling Vireo. — Several seen at Nescopeck, but 

 at no other point. 



47. Mniotilta varia. Black and White Warbler. — Observed at 

 nearly every place visited. I found this species with large young at 

 Harvey's Lake, on June 9, while at Pottsville, on July 7, I found a nest 

 of four young just ready to fly. 



48. Helmitherus vermivorus. Worm-eating Warbler. — Noticed at 

 Pottsville on August 11, in company with a flock of Black and White 

 Warblers and Chickadees. 



49. Compsothlypis americana. Parula Warbler. — A few at Har- 

 vey's Lake, on June 9. A nest which I found was suspended something 

 over twenty feet from the ground, very like a Vireo's nest, from a crotch 

 in a branch. The moss must have been gathered by the birds as there 

 seemed to be but little of it on the tree where the nest was. It contained 

 one egg. 



50. Dendroica aestiva. Yellow Warbler. — Several were seen in 

 Pottsville and one or two in Hazleton. I heard them singing steadily till 

 about the end of July, when they ceased and were no more in evidence. 



51. Dendroica maculosa. Magnolia Warbler. — I found one family 

 at Pottsville. 



52. Dendroica pensylvanica. Chestnlt-sided Warbler. — -Much 

 commoner on the top of the mountains than lower down. At Delano I 

 found it breeding in the scrub oaks, and at Harvey's Lake I found a nest 

 in the laurel. 



53. Dendroica virens. Black-throated Green Warbler. — Pretty 

 generally distributed throughout the coal belt. I found it breeding at 

 Pottsville and saw one or two families near Penn Haven Junction. I also 

 saw it at Mt. Carmel and near Audenried, and found three or four at 

 Rock Glen. 



A nest, which I found at Pottsville on June 23, was situated on the limb 

 of a chestnut tree about thirty feet up and was covered by grape vines. 



^4. Seiurus aurocapillus. Oven-bird. — Pretty common throughout 

 the region. 



55. Seiurus motacilla. Large-billed Water-Thrush. — On June 16, 

 at Hamburg, I found a nest of this species containing four young but a 

 few days old. It was situated in a bank by a stream of running water. 



This record is of some interest as bearing out the experience of others 

 in finding the Water-Thrush breeding well up along our principal rivers 

 at Delaware Water Gap and one or two other points.
