The last time I drove straight through from central Florida to my home in


northeastern Kentucky the trip took 17 hours. Actually my late brother-in-law,


Ross Wright, did all the driving, refusing any relief from me. I think he took


one of those little “truck-driver” pills upon leaving the Sunshine State.


My late father, Bruce, was with us on this 1977 fishing trip to Florida, but he


hadn’t driven a car in more than 50 years, not since he rolled his 1923 Ford


over an embankment after drinking a little too much liquor and shooting a hole


in the dance floor at a local gathering.


He never tasted an alcoholic beverage again and never climbed behind the wheel


of a motorized vehicle again.


But I’m getting off the subject, which is hummingbird migration. These little


birds, weighing less than a nickel, on their migration from here to South


America, fly nonstop across the 500 miles of water making up the Gulf of Mexico.


Their trip takes 18-22 hours, depending on the weather.


Some hummingbirds have been seen landing on offshore oil rigs or fishing boats


to rest.


I attracted only three hummers to my feeder hanging in the front-yard dogwood


tree where I can enjoy watching their activity from the front porch. Yesterday,


only one remained, and he seemed to be feeding up on the red “nectar” my wife


Bonnie mixes, like he was packing his suitcase for the long trip south.


Researchers tell us that some Ruby-throated, one of several species that


frequent our feeders here from late April to early September, remain along


the Gulf coast each winter instead of continuing to Central America, perhaps


because they are too old or sick to make another trans-Gulf flight or too young


(from very late nests) to have had time to grow fat and strong enough to


migrate. Another small population winters in the Outer Banks of North Carolina.


Some hummingbirds live as long as 12 years.


Here’s a few facts I learned about hummingbirds from reading about them on the


Internet. The readers could have done that for themselves, but it’s a fact that


not all readers have computers. There are people in this world who can still


live without one, even without an iPhone.


Some of this remaining column will rate as pure plagiarism, as pure as I can


write it. Plagiarism leaves a bad taste in my mouth. If I was aware of who to


give credit for the writing, I certainly would do so.


INDIVIDUALS

Hummingbirds lead solitary lives and neither live nor migrate in flocks, such as


geese do. Most Ruby-throated Hummingbirds winter between southern Mexico and


northern Panama.


On the return trip, Ruby-throats begin moving north as early as January and by


the end of February they are at the northern coast of Yucatan, gorging on


insects and spiders to add a thick layer of fat in preparation for flying to the


U.S. Some will skirt the Gulf of Mexico and follow the Texas coast north, while


most apparently cross the Gulf, typically leaving at dusk for a nonstop flight.


Individual birds may make landfall anywhere between southern Texas and central


Florida. Before departing, each bird will have nearly doubled its weight, from


about 3.25 grams to over 6 grams; when it reaches the U.S. Gulf coast, it may


weigh only 2.5 grams.


It’s also possible that a few Ruby-throats island-hop across the Caribbean and


enter the U.S. through the Florida Keys.


Sometimes we worry that ants or other insects get into the nectar, but a


hummingbird would probably like that. The nectar they lap up with fringed,


forked tongues is just the fuel to power their fly-catching activity. They are


carnivores, something I certainly did not know.


RETURN TRIP’

The northward migration is complete by late May. Banding studies show that each

bird tends to return every year to the same place it hatched, even visiting the

same feeders.


There is evidence that fewer Ruby-throats cross the Gulf in fall than in spring,


most instead following the Texas coast back into Mexico


The number of birds migrating south in late August and early September may be


twice that of the northward trip, since it includes all immature birds that


hatched during the summer, as well as surviving adults.


For a hummer that just hatched, there’s no memory of past migrations, only an


urge to put on a lot of weight and fly in a particular direction for a certain


amount of time, then look for a good place to spend the winter.


Once it learns such a route, a bird may retrace it every year as long as it


lives. The initial urge is triggered by the shortening length of sunlight as


autumn approaches.


It’s not necessary to take down feeders to force hummingbirds to leave, and in


the fall all the birds at your feeder are already migrating anyway. If you


remove your feeder too soon, birds will just feed elsewhere, but may not bother


to return to your yard the next year.


Immature females may have much lighter streaks in their throats, but no red.
