My wife Kathy and I love to see the hummingbirds arrive at our house in Roscommon! We put feeders out all over the place. We really see all kind of birds that I NEVER see at our place in Canton (in the same county as Detroit
) Anyway, this is a great link to watch the hummers fly north from the Carribbean, plus it has a lot more info if you want it. On this map, if you spot a hummingbird, let them know right away and they will plot it right on there! They should start in the next week or two to arrive in the south.
