In the discussion of the Florida Greenlet, the author used a ‘y’ with a breve above it to describe the song sound. As this character does not exist in UTF-8, a macron was used instead of a breve.
Obvious printing errors were corrected, such as duplicate words, upside down letters, numbers printed backwards, and letters or spacing in the wrong order.
Missing punctuation was added to ends of sentences and abbreviations. Unprinted letters and numbers were added, where appropriate. A description of the illustration on the title page was added.
