Greetings All: Does anybody know (and this is Texas related, David, given some of the splits and such) what the initials CSi mean when appearing in a table of contents. Evidently one is supposed to peruse CSi for the 55th Supplement to the AOU Checklist in the October edition of The Auk but there is no explanation of what or how one is expected to do this ... and all computer queries about potential definitions lead to a popular television show. Will post some interesting birding highlights from Lubbock later today.
