Enter a checklist for Birds Of Florida or even the USA.
Is it possible to have a Florida specific or USA list rather than using the whole world list?

Yes it is. Create a custom Checklist and copy existing list and edit it. If you do not see a list you can copy check the Library section and install one that is as close as possible, e.g. Birds of the United States (IOC).
