If you go to the site for Journey south, you can post your sightings of any kind of hummingbirds. It puts it on a map and also list the sightings so you can post how many, make, female, juvies, etc. It is fun to watch the trip south and lets you know when you should be ready with your feeders.

I will try to link it here. http://www.learner.org/jnorth/humm/fall2012/update090712.html
