An email from Bristol resident Ralph Beamer offered a timely reminder about the need to keep a watchful eye on our sugar water feeders even as most of the ruby-throated hummingbirds depart the region.
“For the past week, I have had a red humming bird coming to the feeder,” Ralph explained in his email. He added that he had never seen a hummingbird like this recent visitor.
“Have you had any reports of a similar sighting?” Ralph asked.
Ralph is the first person to make such a report this fall, but sightings of a species of hummingbird other than the expected ruby-throated hummingbird are becoming more commonplace each year. Once the numbers of ruby-throated hummingbirds are reduced as these tiny birds migrate from the region, noticing an unusual hummingbird at a feeder becomes even easier.
In a reply to Ralph’s email, I sought more information on the hummingbird’s coloration. He confirmed that the bird’s feathers looked more reddish brown than bright red, which supports my belief that he has received a visit from a rufous hummingbird.
I speak from personal experience. My yard has attracted rufous hummingbirds on a couple of occasions. In October of 2016 I received my most recent visit from a rufous hummingbird, which lingered into November and was banded by Mark Armstrong. A former curator of birds for the Knoxville Zoo, Armstrong has devoted several years to studying the phenomenon of rufous hummingbirds that appear to migrate on a regular basis through the eastern United States every fall and early winter. Mark’s efforts have largely focused on Tennessee reports of rufous hummingbirds, but other banders operating from the Gulf Coast to New England have confirmed rufous hummingbirds in their respective regions.
The possibility of attracting a rufous hummingbird is the reason I encourage others to keep a sugar water feeder available into October and November. Experts who have studied the matter note that the presence of a feeder will not encourage ruby-throated hummingbirds to linger. These tiny birds know instinctively when it’s time to depart. Without the attraction of a feeder, however, a visiting rufous hummingbird might reject any extended stay in your yard.
Selasphorus rufus, or the rufous hummingbird, is about the same size as the ruby-throated hummingbird. Both species reach a body length of a little more than three inches and weigh only a few grams. In fact, one of these small hummingbirds might weigh the equivalent of a dime. Female rufous hummingbirds are slightly bigger than males, so a well-fed female rufous hummingbird might weigh as much as a nickel. So, to get an accurate impression of this sort of size, simply think of these tiny birds as weighing less than some of the spare change in your pocket.
Although hummingbirds are not known for their longevity, the website for Tennessee Watchable Wildlife notes that the oldest rufous hummingbird on record reached an age of eight years and 11 months. For the most part, hummingbirds blaze like tiny comets and enjoy typically brief but fast-paced lives. Despite a prevalent impression, hummingbirds are not delicate creatures. For instance, the rufous hummingbird’s tolerance for cold allows it to survive temperatures that dip briefly below zero. This adaptation has allowed the rufous hummingbird to breed as far north as Alaska.
The Selasphorus genus of hummingbirds consists of the rufous and six other species. Of those species, the Allen’s hummingbird, broad-tailed hummingbird and calliope hummingbird are known to also migrate through the eastern United States although with less frequency than the rufous. The remaining Selaphorus hummers — scintillant hummingbird, glow-throated hummingbird and volcano hummingbird — range in the tropical regions of Costa Rica and Panama. Those rufous hummingbirds that don’t spend the fall and early winter in the southeastern United States choose to overwinter in the region of Mexico around the city of Acapulco. This majority of the rufous hummingbird population migrates north again in the spring to claim nesting territory that can range from the Rocky Mountains of the western United States, as well as the Pacific Coast states of California, Oregon and Washington, all the way north to southern Alaska, as well as British Columbia in Canada.
Those rufous hummingbirds that continue to migrate through the southeastern United States each autumn constitute more evidence that we still have a lot to learn about birds. Even an abundant species like the rufous hummingbird offers mysteries that curious humans can attempt to understand.
While I can’t guarantee hummingbirds, I want to remind readers of the bird walks at 8 a.m. each Saturday in October at Sycamore Shoals State Historic Park in Elizabethton, Tennessee. Remaining walks, which are free and open to the public, are scheduled for Oct. 21 and Oct. 28. Meet at the parking lot at the park’s visitors center. Bring binoculars to increase your viewing pleasure.
