Thanks! I'm not bad with the books. I have Peterson's A Field Guide to the Birds, 2nd ed (1947) with all the helpful color plates and detailed sections by family.

I was wondering if an app could have better local suggestions because I'm out of practice. I sometimes feel betrayed when the range map shows like 60% of North America, but I need to know if it's the right season for migratory birds. Maybe I should hit up the bookstore for a Michigan/Midwest birding book for stuff like that.
