Illustrations moved to prevent splitting paragraphs. Minor typos
corrected. Hyphenation was standardized to the most prevalent used
except those in the Bibliography which were left as printed. The
Index entry _Seiurus noveboracensis_ (Northern Waterthrush) points to
page 52 where the _Seiurus aurocapilla_ (Ovenbird) is described. The
species name in the Index is likely a typo and has been changed.
