dozen specimens of this species in Chester and Lancaster counties previ- 

 ous to 1882, but have not seen any since that time. 



" Olive-sided Flycatcher, Contofus borealis. — In looking over my 

 Entomological notes I find in reference to this species : Sept. 30, '87, 

 secured two males near Coatesville along the Brandywine road, feeding 

 upon Red Ants, Formica sanguined. Upon examination of the stomachs, 

 I found them to contain besides the Red Ants : Black Crickets, Acheta 

 nigra; MosquitoeSj Culex fifiiens and two House Flies, Musca do- 

 me stica. 



"Yellow-bellied Flycatcher, Emftidonax flaviventris. — I remem- 

 ber collecting this bird upon one occasion during the breeding season, and 

 have no doubt that it would be more frequently met with but for its 

 resemblance to C. virens at a distance. 



" American Crossbill, Loxia curvirostra minor.- — Several secured 

 during the great blizzard of March, 1888. Dr. A. K. Fisher took them 

 during this storm, as far south as Washington, D. C. 



"White-winged Crossbill, L. leucoftera. — One taken during the 

 same storm. 



' ' Bohemian Waxwing, Amfelis garrulus. — I shot two specimens during 

 the same blizzard. Climatic conditions have so much to do with bird life 

 that in order to be posted upon each species, one must have the necessary 

 field experience. If we fail to look for northern species during the cold 

 and stormy days we will never secure them. 



" Pa'rula Warbler, Com-fsothlyf>is americana . — In 1883 I found this 

 bird breeding along the Octoraro creek which borders the county. Turn- 

 ing to such high authority as Mr. H. Nehrling and Prof. Ridgway, we 

 find them saying : ' From Maine and Canada to Texas it seems to make 

 itself at home where ever it can find a nesting place ; ' and further ' It 

 ranges from the Atlantic to the Plains, north to Canada. In Conneticut, 

 Wisconsin, Illinois, Pennsylvania, Michigan New Jersey and most of the 

 states bordering on the Atlantic it seems to be common.' 



" Cape May Warbler. Dendroica tigrina. — Mr. Wood, of Philadel- 

 phia, took this species near Coatesville. This specimen is now owned by 

 Mr. Thomas Windle, of the firm of Windle and Doan, Coatesville. 



" Blackburnian Warbler, D. blackburiiioe. — I have met with this 

 species in the county as a transient visitant only, but met wi^h a single 

 pair in Lancaster county, north of Columbia, along the Susquehanna, 

 late in June, paired and the male in full song. 



"Pine Warbler, D. vigor sii. — I have met with it on two occasions, 

 once in the spruces south of Coatesville, and the second time in what is
