22 The Ornithology of Chester County 



material to a large extent was obtained in the town- 

 ships of Willistown, Pocopson, Newlin, and those 

 bordering West Chester. With the assistance of 

 his friend, Benj. M. Everhart, he compiled a num- 

 ber of interesting local names. As the list was 

 prepared for a newspaper, the technical names were 

 omitted, though the species are checked with num- 

 bers to correspond to those used by Ridgway in his 

 Nomenclature of 1881, for the benefit of scientific 

 contemporaries. 



C. J. Pennock 30 of Kcnnett Square, in March, 

 1886, published his original list, which apparently 

 had a very limited circulation among ornithologists 

 and is now quite scarce. This paper is compiled 

 from the writer's own observations and the published 

 lists of his predecessors, and adds one new species 

 to the county: the Wood Ibis, taken by his uncle, 

 Vincent Barnard. In common with Michener, Pen- 

 nock appears especially concerned in the economic 

 value of the bird as revealed by its food habits, and 

 his oological inclination given expression in brief 

 notes on nidification. The list, though meritorious, 

 exhibits every evidence of haste and is unequal to 

 the high standard of his later papers. He has in- 

 cluded Michener's hypothetical species, 37 the ques- 

 tionable Mississippi Kite, White Gyrfalcon and Red- 

 cockaded Woodpecker, of which there appears no 

 satisfactory record ; as well as several other species 

 without indicating that they had long since become 

 locally extinct; on the other hand the Black-throat- 

 ed Green Warbler has doubtless been omitted unin- 

 tentionally. The list embraces 236 species, of which
