There is a very nice site called Hummingbird Central that allows you track the progress and location of hummingbirds who are migrating. Visitors to the site can report the sighting of a hummingbird which updates the site.
They been seen in both South and North Carolina. In NC they’ve been seen in Wilmington so they are on their way to Cary. I’ve got my feeder out and none of my potted hummingbird plants are blooming yet but I ordered some flowers from Almost Eden, that should arrive Wednesday. So I expect to see a hummingbird in the next 2 weeks (fingers crossed).
