You can read all of the observations people have submitted at this link. Here are some of the highlights:

"Jeepers! I had to put up 14 more feeders yesterday!" moaned Meridian, Mississippi.

"Ten days ago we had an average of 10 birds now we have 25 to 30," noted New Hope, Alabama.

"At times they sound like a swarm of bees there are so many," says Somerset, Kentucky.

"They're eating over a gallon a day out of 5 feeders, and this is how it looks," tattled a chap from Chappel Hill, Texas. (See picture.)

In Arcadia, California there were: "Hummers, hummers EVERYWHERE, all day, from early morning to dusk. Zipping, chirping, chasing, fighting, displaying, posturing and whirring feathered bodies filled the skies. The numbers are staggering. I don't believe I've ever had so many energetic and hungry guests before."

Meanwhile, times looked tough in Texas where Tropical Storm Hermine packed 70 mph winds. When the weather cleared the next day, the news looked good in at least one backyard:

"The extreme wind and rain around has come to an end, and we still have Ruby-throated hummingbirds in good numbers. For a few hours yesterday morning there were only three or four hummers around after the 70 mph winds but, by late afternoon, there were 12 to 15 in the backyard."

Way up north in Nova Scotia, it's time to say goodbye:

"It was a wonderful summer here and the hummers had good weather and good feeding. I had 18 here with the new hatchlings, and still have 4 here this morning. Am not looking forward to their leaving and no longer hearing the whir of their wings and the 'cheep, cheep, cheep' of their calls."

Further south along the migration trail came this reminder:

"Keep your feeders fresh! Here in Vermont we still have traveling hummers passing through and stopping for a drink. We are seeing more transients this year than ever before (and this was our 23rd hummer summer)!"
