1) Paragraphs split by illustrations or tables were rejoined.
2) The illustrations were placed above the section describing the species illustrated.
3) The following errata notes displayed on the bottom of pages 112, 114 and 116 in the original publication have been applied:
"In the make-up of a few pages on the shore birds, the scientific names have become transposed.
They should read:
[Page 112]: Dowitcher (Macrohampus scolopaceus).
[Page 114]: Yellow-legs (Totanus melanoleucus).
" " : Marlin (Limosa fedora).
[Page 116]: Red-backed sandpiper (Tringa alpina pacifica).
" " : Willet (Symphemia Semipalmata inornata)."
4) There appears to be text missing under the description of "WILSON'S PLOVER" in the "Measurements" section on [page 125].
A note was inserted to that effect
5) The Æ ligature which was used in the caption of the image on [page 122] has been changed to the letters "AE" for consistancy with the way those names are displayed elsewhere in the book.
