Santa Marta Sabrewing

Campylopterus phainopeplus

FAMILY

Hummingbirds (Trochilidae)

LAST DOCUMENTED

2010

(13 years)

REGION

South America

IUCN STATUS

Critically Endangered

Background

One of four hummingbirds endemic to the isolated Santa Marta Mountains of northern Colombia. This species has now been rediscovered twice within the last century: once, briefly, in 2010 (after 64 years!) and again in 2022. Ongoing work following its most recent rediscovery will soon provide additional insight into this bird’s ecology, which we await with great anticipation.

Last Documented

Prior to its most recent rediscovery in July 2022, the last photograph (of a mist-net captured individual) hailed from the northwestern corner of the Santa Marta Mountains (March 2010).

  • Rare singing, emerald-green and iridescent-blue hummingbird unexpectedly rediscovered in Colombia

    Cameron Rutt / 1 May 2023

    An experienced local birdwatcher in Colombia rediscovered the Santa Marta Sabrewing (Campylopterus phainopeplus), a relatively large hummingbird only found in the country's Sierra Nevada de Santa Marta mountains. It's only the second time the species has had a documented sighting since it was first collected in 1946. The last time was in 2010, when researchers captured the first-ever photos of the species in the wild. The Santa Marta Sabrewing is so rare and elusive that it was included as one of the top 10 most wanted lost birds by the Search for Lost Birds.

    “This sighting was a complete surprise, but a very welcome one,” said Yurgen Vega, who made the rediscovery while working with SELVA, ProCAT Colombia, and World Parrot Trust to study endemic birds in the Sierra Nevada de Santa Marta. “As I was leaving the area where I had been working, a hummingbird caught my attention. I got out my binoculars and was shocked to see that it was a Santa Marta Sabrewing, and in an incredible stroke of luck the hummingbird perched on a branch, giving me time to take photos and video.”

    The male hummingbird was instantly recognizable by its emerald-green feathers, bright iridescent-blue throat, and curved black bill. It was perched on a branch, vocalizing and singing, which scientists think is a behavior associated with defending territory and courtship. However, Vega did not see any other hummingbirds in the area, though there have been sporadic reports of Santa Marta Sabrewing sightings during the past decade by other local birdwatchers. Researchers believe the population of Santa Marta Sabrewings in the Sierra Nevada de Santa Marta is very small and decreasing. The species is listed as Critically Endangered on the IUCN (International Union for Conservation of Nature) Red List of Threatened Species, though it was historically common in the southeastern part of the mountains.

    The Sierra Nevada de Santa Marta is the world's tallest coastal mountain massif and home to rich communities of wildlife, including 24 species of birds that are found nowhere else on the planet. It partially overlaps with five Key Biodiversity Areas, which are sites of global importance to the planet's overall health and the persistence of biodiversity. It is also an Alliance for Zero Extinction site due to the multiple species there that are found nowhere else.

    “This rediscovery is tremendous, and it makes me hopeful that we will start to better understand this mysterious and threatened bird,” said Esteban Botero-Delgadillo, Director of Conservation Science with SELVA: Research for Conservation in the Neotropics. “However, we found it in an area that is unprotected, which means that it is critically important for conservationists, local communities, and government institutions to work together to learn more about the hummingbirds and protect them and their habitat before it's too late.”

    Scientists know very little about the Santa Marta Sabrewing, except that it typically lives in humid Neotropical forests at mid-elevations between 4,000 and 6,000 feet. Ornithologists believe that the hummingbird may be migratory, moving up to even higher elevations in the páramo — an ecosystem of grass and shrubs — during the rainy season, in search of flowering plants. Much of the forest in the Santa Marta Mountains has been cleared for agriculture, and scientists estimate that only 15 percent remains.

    “Technology has made it much easier to gain and share knowledge about the Sierra Nevada de Santa Marta and its inhabitants,” said Diego Zárrate, Director of Conservation with ProCAT Colombia. “This is a great example of what we can learn about the biodiversity of this area when local communities and conservationists work together.”

    The rediscovery of the Santa Marta Sabrewing is being celebrated by ornithologists around the world, including those working as part of the Search for Lost Birds, a collaboration between Re:wild, American Bird Conservancy (ABC), and BirdLife International.

    “It's so incredible to see photos and video of the Santa Marta Sabrewing,” said John C. Mittermeier, Director of Threatened Species Outreach at ABC. “It's like seeing a phantom. When we announced the top 10 most wanted lost birds last year, we hoped that it would inspire birders to look for these species. And as this rediscovery shows, sometimes lost species re-emerge when we least expect it. Hopefully, rediscoveries like this will inspire conservation action.”
