--Spelling, capitalization, and punctuation of bird names was made
consistent (_e.g._, "Redhead" _vs._ "Red-head" _vs._ "Redheaded"). All
spelling changes were justified by usage elsewhere in the text.
Unambiguous abbreviated names ("American Sparrow Hawk" _vs._ "Sparrow
Hawk") were not changed.
--Note that the "Yellow Warbler" is also once called "Summer Warbler".
--The "Canvas-back Duck" was, apparently unintentionally, omitted from
the bird list, but is referenced several times in the text.
--Two tables, the "Identification Key" and "Tables of Arrival", were
reformatted for vertical scrolling.
--In the ASCII text file, an * (asterisk) indicates that the following
bird name or number was printed in *bold font.
