1 8 The Ornithology of Chester County 



individual flying over on Oct. 20, 1852 ; is also prob- 

 ably erroneous, since the date is well within the 

 period when the Marsh Hawk frequents the county, 

 and as the author does not include the latter species 

 in his list, it is possible that he may have mistaken 

 it in the gray plumage of the male. Michener's 

 Warbler appears to have been an immature Con- 

 necticut Warbler, though there may be a reasonable 

 doubt since the type taken by Michener in Chester 

 county in the autumn of 1839, cannot be found. 

 Barnard's collection was purchased by the Swarth- 

 more College. 



Dr. Ezra Michener" 3 of "Sylvania," Avondale, 

 practitioner, poet and naturalist; was one of the 

 earliest of our local ornithologists, though he did 

 not publish his first list until two years after Bar- 

 nard. The material, however, he informs us later, 

 was collected mostly between the years of 1834 an d 

 1840. He omits the water birds for want of space, 

 and one species, the Red-winged Blackbird, doubt- 

 less unintentionally. The list of 186 species is freely 

 annotated and while it contains some mistakes, rep- 

 resents by far the best efforts of the author. Red- 

 cockaded Woodpecker and Gray-cheeked Thrush are 

 probable errors since they do not appear in his later 

 list; while the Black Hawk, Mottled Owl, Mich- 

 ener's Warbler and Wood Wren appear identical 

 with well known species, as he suspects. 



Dr. Michener made the following quaint record 

 on comparison of his own and Barnard's lists: "29th 

 of ist mo., 1861. There have been discovered in 

 the County, to this time Two Hundred Species; and
