Birders

and there's always eBird, which is a good way to contribute to citizen science while managing your checklists. There are some things about it that are quirky in terms of listing (at least to me) - such as it doesn't seem to distinguish if a bird is acceptable on a state list. I've told the Ohio reviewers for eBird not to expect any Trumpeter Swan reports from me, since the bird is not on our state list as an introduced species and I don't want my personal state list count to be screwed up. Same thing with ABA (American Birding Association) area list - I have to mentally subtract a couple of birds I saw in Florida that are on the state list but not on the ABA list.

I suspect you aren't at that level of listing yet!
