The July issue of the Auk contains the 49th Supplement to the AOU 
Check-list. It is not yet on line, but will be soon, at 
http://aou.org/checklist/index.php3 . Few of the most anticipated 
changes have appeared (see a summary of these at 
http://aou.org/committees/nacc/proposals/pending.php3  , where a much 
longer version is available by calling up the PDF).
     For North America, species have been added, nothing subtracted. The 
flamingo has been moved up after the grebes. Changes affecting the Ohio 
list are even fewer. The hyphen has been removed from what is now the 
violetear. Research has resulted in a rearrangement of the taxonomic 
order among the gulls, and a number of them formerly in the genus Larus 
have been returned to older names in accordance with taxonomic principle.
Here is the revised list of Ohio gulls:

Rissa tridactyla  Black-legged Kittiwake
Pagophila eburnea  Ivory Gull
Xema sabini  Sabine’s Gull
Chroicocephalus philadelphia  Bonaparte’s Gull
Chroicocephalus ridibundus  Black-headed Gull
Hydrocoloeus minutus  Little Gull
Rhodostethia rosea  Ross’s Gull
Leucophaeus atricilla  Laughing Gull
Leucophaeus pipixcan  Franklin’s Gull
Larus heermanni  Heermann’s Gull
Larus canus  Mew Gull
Larus delawarensis  Ring-billed Gull
Larus californicus  California Gull
Larus argentatus  Herring Gull
Larus thayeri  Thayer’s Gull
Larus glaucoides  Iceland Gull
Larus fuscus  Lesser Black-backed Gull
Larus hyperboreus  Glaucous Gull
Larus marinus  Great Black-backed Gull
     True, they're not as easy to pronounce or spell as "Larus,"  but 
those are the cards we're dealt. If you're working on anything for 
publication, take account of these.  And practice your Greek.
