A Jewel in the Understory
The Band-tailed Barbthroat (Threnetes ruckeri) is a medium-sized hummingbird, a shimmering marvel measuring only 10-11 centimeters. While not as common as some of its flashy relatives, spotting it is a guaranteed thrill.
A Glimpse of Its Plumage
The male Band-tailed Barbthroat is a sight to behold. Its upper parts shine with a bronzy-green glow, contrasting sharply with a dark patch on the ear and chin. A dark stripe runs along its cheek, adding a touch of intrigue. But the true star is the tail. Black feathers with bright white tips create a striking barred pattern, a namesake feature that flashes when the bird takes flight.
Un Festín para los Sentidos
The Band-tailed Barbthroat prefers the shaded embrace of the understory, flitting among Heliconia and other tubular flowers. Its long, slightly curved bill (yellowish underneath) is perfectly adapted to probe deeply into these flowers, extracting the sweet nectar that fuels its frenetic energy.
But the Band-tailed Barbthroat is not just a nectar lover. This tiny hunter also supplements its diet with small arthropods, especially spiders. It employs a fascinating technique called «trap-lining,» visiting a circuit of flowering plants it knows offer both nectar and potential prey.
A Whirlwind of Activity
Unlike some hummingbirds that hover gracefully, the Band-tailed Barbthroat tends to visit flowers in brief bursts. You might catch a glimpse of its vibrant plumage as it darts among flowers, its wings buzzing with a characteristic high-pitched trill.
A Fortuitous Encounter at the Retreat
While the Band-tailed Barbthroat is not as widespread as some hummingbirds, guests venturing to the higher elevations of our mountain retreat might be lucky enough to spot this dazzling jewel. Keep your eyes peeled near patches of Heliconia in the understory and listen for the telltale buzz of its wings.
If you are fortunate enough to encounter this little marvel, take a moment to appreciate its beauty. The Band-tailed Barbthroat is a living testament to the vibrant tapestry of life woven into the Costa Rican mountains.
