Click on Species at the top and choose one in your area. Then scroll down and click on ``species account``, from there click on BBS(Breeding Bird Survey) on the left of your screen and a map will pop up showing the birds` range. If they are in your area and your feeder is up they will most likely find it - sometimes within minutes!

Here is a link that might be useful: Hummingbird Migration

Thanks for the information about how to use the migration site, shilla. Very interesting.
