Oh, what's up w/ the color coded list? The color scheme shown in the summary above is based on documentation requirements for the individual species:
Category 1: No documentation required, unless (a) new to your count or (b) observed on fewer than 10% of your counts, in which case documentation may be as little at 3-4 sentences describing the bird and where found.
Category 2: Documention must be at least a paragraph or two describing the bird in detail, as well as location and circumstances of the observation.
Category 3: Full documentation is required, including all of the information requested on the enclosed rare bird documentation form.
