Taxonomically

 * Many of the tanagers, e.g. scarlet, summer are now in Cardinalidae. However, it is possible that the book was printed before this was changed.


 * The gnatcatchers are listed under Sylviidae. It should be in Polioptilidae.


 * The Lanceolated Warbler and Middendorf's Grasshopper-warbler are listed under Sylviidae. They should be in Locustellidae.


 * The same thing happened to the Dusky Warbler, Arctic Warbler, Willow Warbler and Wood Warbler (albeit the last two are in the Accidentals, Extinct Species section) are listed under Sylviidae. They should be Phylloscopidae.

Typos

Taxonomic errors

 * Many species (e.g. Baikal Teal) are still in Anas.
 * White-faced Storm-Petrel and Wilson's Storm-Petrel should be in Oceanitidae, not Hydrobatidae.
 * Band-rumped Storm-Petrel should be in Thalobata; Fork-tailed Storm-Petrel should be in Hydrobates; Wedge-rumped Storm-Petrel, Leach's Storm-Petrel, Least Storm-Petrel, Black Storm-Petrel should be in Halocyptena while Ashy Storm-Petrel should be in Cymochorea. Oceanodroma'' is essential dissolved.
 * American Egret is split from the Great Egret - its scientific should be Casmerodius egretta, not Ardea alba.

The taxonomic order of birds

 * Loons are still placed near the grebes, when they should be placed after cranes and before Procellariiformes. Grebes should be placed after the flamingos (and before flamingos, the gamebirds) - note: as I was flipping through the book, the Procellariiformes comes after the grebes.


 * Tropicbirds should be closer to flamingos and grebes.


 * New World vultures and Accipitriformes should come after Charadriiformes, not flamingos.


 * Falcons should come after woodpeckers and before parrots.

Corrections

 * The two bean-geese are split into two species.
 * Spot-billed Duck is now Eastern Spot-billed Duck.
