A Record-Breaking Male Ruby-throated Hummingbird

In the tapestry of nature, few creatures capture the imagination quite like a hummingbird. With their iridescent plumage, impossibly rapid wingbeats, and boundless energy, these diminutive birds seem touched by magic. Yet, beyond their well-known feats of aerial agility and long migrations, a more subtle marvel has occurred in Dover, Tennessee, the record-breaking lifespan of an adult male ruby-throated hummingbird. This tiny bird, defying all odds, has rewritten the limits of longevity for males of its species much to the delight of the hummer’s dedicated and longtime hummer host, friends and Southeastern Avian Research.

The story of this record-breaking male hummingbird began on a sunny summer morning in July of 2017 at the home of Mrs. Bonnie Crutcher.  Southeastern Avian Research had been invited to band hummingbirds at her residence as part of our migration study because as we were told by other Stewart County residents, “Ms. Bonnie had lots of hummingbirds…”

So, on July 14, 2017, we set up our traps and we banded 78 ruby-throated hummingbirds including adult male ruby-throat K78219 at Ms. Bonnie’s feeders.  By all accounts a very  successful first morning up on top of Crutcher ridge.  We saw male K78219 again in 2018, 2020, 2021 and then not again until 2024.  When we re-caught him in August of 2024, he was 8 years, 2 months old.   Knowing the longevity record for ruby-throated hummingbirds was 9 years and 2 month and that bird was a female, our excitement began to rise, and we began to wonder if perhaps he was a male record?  A quick email to the Bird Banding Laboratory and we were informed there were a few a ‘bit older’.

We thought about K78219 all winter and again as I worked on the schedule for summer/fall migration banding with anticipation.

On July 22, 2025, we once again arrived at the Crutcher home.  Ms. Bonnie had lemonade and cookies waiting for us and a sense of excitement filled the air.  Family and friends began arriving, traps went up and shortly after 8am K78219 was ‘in-hand’!   At 9 years, 1 month, I held in hand the oldest known male ruby-throated hummingbird.  Ms. Bonnie, herself a young, spry 96 years old, couldn’t believe it. But there he was, itching to get loose and head back to the feeders.  Which he did and was re-caught 2 other times that morning.

The reasons behind extraordinary longevity in hummingbirds are still being unraveled. Hummingbirds face an array of dangers: predatory birds, inclement weather, habitat loss, collisions with windows, and the immense physical demands of their daily routines. For a hummingbird to survive for nearly a decade, every factor must align in its favor.

Genetics may play a significant role. Some birds may be born with naturally robust constitutions, superior immune systems, or metabolic quirks that help them weather the trials of life more successfully than their peers.

Habitat quality is another major influence. Birds living in locations rich in flowers, with abundant food and suitable nesting sites, are more likely to thrive.

Behavioral strategies might also contribute. Older, more experienced birds tend to become adept at avoiding dangers, finding the best territories, and timing their migrations to coincide with favorable conditions.

The discovery of such a long-lived hummingbird is more than a scientific curiosity; it has practical implications for conservation. If some individuals can survive so much longer than previously thought, it suggests that under the right conditions, population longevity can be enhanced. Protecting critical habitats, ensuring connectivity across migratory routes, and minimizing human-caused dangers may make a profound difference.

For SEAR, this remarkable bird, along with others, offers a living laboratory. By studying the life history—diet, movements, nesting success, migration patterns—we can gain valuable insights into the factors that promote avian longevity. This knowledge can then help plan strategies to protect not just hummingbirds, but a wide array of migratory birds facing similar challenges.

Beyond science, the story of this male hummingbird resonates on a deeper level. Across cultures, hummingbirds symbolize resilience, joy, and the triumph of spirit over adversity. The idea that such a tiny creature can endure and flourish through almost a decade of storms and migrations is a powerful metaphor.

It also underscores the importance of long-term research and community science.  It was the collaboration of an enthusiastic hummingbird host who for years created a wonderfully rounded habitat for her hummingbirds, dedicated SEAR volunteers, and years of record-keeping that allowed this discovery to be made.  And as technology advances with the advent of light radio-tracking devices, who knows what else we might discover?

As climate change and habitat destruction threaten all bird populations worldwide, maybe the story of this remarkable little hummingbird will help remind us that even tiny measures, such as planting native flowers or preserving migration corridors, can yield outsized rewards.

In the end, the hummingbird’s story is one of hope—hope that with care, attention, and respect for nature, life can flourish in all its dazzling diversity and tenacity. And perhaps, as we watch these tiny jewels flit from blossom to blossom, we are reminded of the boundless possibilities that await when life is given the chance to endure.

CTT Radio tagging update…

On June 12^th we announced deployment of 15 BluMorpho Cellular Tracking Technology radio tags on ruby-throated hummingbirds on June 11^th at 3 locations; a first for Tennessee!  Since then, our hosts have reported both daily ‘pings’ and visual sightings of our tagged hummers at their feeders.  We have also visited each location with our SideKick antenna allowing us to search a bit further away from the feeders to try and locate our tagged birds.

We had the opportunity to do some regular banding at all 3 locations since then and we were able to track the movement of one of our males as he moved around his territory at Woodlands Nature Center and at The South Welcome Station of LBL we were able to capture one of our CTT tagged females.

 I’m happy to report the female we captured is in fine condition and weight with evidence of nesting.  The tag is still firmly in place and did not appear to hinder her movement or her ability to eat, chase off the competition at the feeders, or zip off into the canopy nearby.

We will continue to monitor these 15 ground-breaking hummingbirds daily and update you on our findings once we analyze the data.

THANKS to all who supported this effort as we continue to work together to learn all we can about these fascinating little birds!
