Birds I hope to see in Ohio - Midwest Birding Symposium

In my excitement to attend the Midwest Birding Symposium, I scoured eBird to create for myself a list of birds that I can hope to see.  I ran a report in eBird to show me all the bird sightings for September for the Lakeside area and adjacent counties.   Then I downloaded the data into Excel so I could view it on a week-by-week basis and focus on the middle two weeks of September.  Then I narrowed down the list so that it only shows my potential life birds.  After that, I sorted the bird species by the frequency reported, to create this silly little probability chart:

This chart establishes the list of species I need to study.  Using my arsenal of birding field guidebooks I hope to be prepared to identify them correctly in the field.

Now, I am open to advice from birders familiar with this area that can steer me in the right direction or tell me that my chart is completely useless.  This chart is based off of fellow eBirder sightings only, so it may not be perfectly accurate - we just need more eBirders!!!

I plan on birding intensely on Friday and Saturday mornings before the presentations begin.  I understand that the Symposium organizers have volunteer bird guides stationed at local hotspots.  I hope that they too can help me.  If you are planning to attend and think you can help show me the ropes, please let me know!

P.S.  I only need 14 birds to hit the 400 Life Bird mark, which is likely to happen during the Midwest Birding Symposium.  It will be an exciting time!  Come and see the life bird dance for yourself when I hit 400!!!
