Bruce Anderson of Winter Parkreviewed this season’s 246 rare-bird doc-umentation forms, for which I am mostgrateful. I deleted 55 reports submittedwith little or no documentation, and Iappended with the “DD” (DetailsDesired) annotation 43 other reports.The number of deletions remains steadyat around 0.5 percent of all reports sub-mitted, an amount that seemsimpossible to improve upon. Dates andlocations for all Florida CBCs, alongwith my letter of instruction to compilers,are posted to the website of the FloridaOrnithological Society (http://fosbirds.org).

Correction: In my summary for the108th season (American Birds 62:67–69), I failed to note that the SarasotaCBC attained 161 species.
