When Will Your Hummers Arrive?
Look at wind maps to predict which days hummers will cross the Gulf of Mexico, and then watch the Journey North map to see when and where sightings are reported from the Gulf States. Once in North America, migration proceeds at an average rate of about 20 miles per day, generally following the earliest blooming of flowers hummers prefer. When your hummingbirds arrive they will be eager to eat from your nectar-filled feeders and flowers!
