Jimmy I am wondering if you saw a hummingbird moth especially since you say it was brown. Not saying you did not see a hummingbird but it doesn't sound like a Ruby-throated hummingbird and those are the ones aound the southeast right now.

I've lived in Orlando 30 years and only recently have I had hummingbirds - ever since I started growing flowers they are attracted to. Depending on how the sun reflects off them, their color changes.
