Use this hummingbird migration map to follow the progress of the Ruby-throated hummingbird.
Once in the US, the Ruby-throated hummingbird migration will continue at a rate of about 20 miles per day following the early blooms of the flowers that the Ruby-throats prefer as a food source. The northern migration is usually completed by the end of May. Banding studies have shown that each bird will return to the area where it hatched, even returning to the same nesting sites nesting sites year after year.
Be sure to set your hummingbird feeders hummingbird feeders out a week or two before the estimated arrival date. That way when the hummers arrive they will find you first and hopefully hang around all summer.
