18 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. Mlichener’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?* 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 and 
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 Iwo Hundred Species; and
