The 49th Supplement to the AOU Check-list of North American birds is now

Here are some interesting changes:

Flamingos are now placed immediately after the grebes (Podicipediformes) in the check-list sequence and Old World Phoenicopterus roseus is split from
New World Ph. ruber; the latter is now called American Flamingo.

Herring Gull - proposal to split smithsonianus and vegae from argentatus did not pass muster

Latin name of following gulls
Chroicocephalus philadelphia Bonaparte’s Gull
Chroicocephalus cirrocephalus Gray-hoodedGull
Chroicocephalus ridibundus Black-headedGull

Also, several New World thrushes in the genus Turdus
that were formerly called "robin" (eg Clay-colored and White-throated) are now called "thrush". However, Rufous-backed Robin along with American Robin are excluded.

Any thoughts or complaints?
