Hummingbirds migrating back to Central America

I had about 8 hummingbirds born here this summer now I have about 45 of them and all have white tips on their tails indicating that they were born this summer. They are traveling through my southern state on their way to winter in central america. I guess someone told them that Sheri has a bed and breakfast and stop by to get some sugar water and get stronger for their flight across the Gulf of Mexico ocean towards Central America.
