The green-tailed trainbearer (Lesbia nuna) is a species of hummingbird in the "coquettes", tribe Lesbiini of subfamily Lesbiinae. It is found in Bolivia, Colombia, Ecuador, Peru, and possibly Venezuela. The taxonomy of the green-tailed trainbearer is not settled. The International Ornithological Committee (IOC) recognizes these six subspecies:
Though the green-tailed trainbearer shares its genus with the black-tailed trainbearer (L. victoriae), they might not be especially closely related. All of the subspecies except the nominate (and boliviana) have at various times been suggested as separate species. Two additional subspecies have been proposed as well, but the weight of evidence is that they are hybrids of the two trainbearers.

Rare
Under 5% of wildlife watchers report a Green-tailed Trainbearer sighting in Podocarpus National Park on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 264th most-seen of the 446 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Green-tailed Trainbearer in Podocarpus National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Green-tailed Trainbearer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Green-tailed Trainbearer sightings, Podocarpus National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Chingaza National Natural Park (Colombia, under 5%).
Same family: Trochilidae
The closest relatives of the Green-tailed Trainbearer that you can see in Podocarpus National Park (family Trochilidae, Hummingbirds) are Collared Inca (about 40%), Amethyst-throated Sunangel (about 40%) and Chestnut-breasted Coronet (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green-tailed Trainbearer is recorded against all the birds logged in Podocarpus National Park (31 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
