For the Northeast the changes are basically nothing. The Northwest Crow
was lumped with the American Crow and the Mexican Mallard (now Mexican
Duck) was split from the Mallard. More changes in the west and Mexico
and points south. There were a number of sequence changes but most are
minor. Only the Turkey / Grouse / Pheasant sequence changes for us.

There are many more changes, lots in hummingbirds. But we got off mostly
for free.
