The Buffy Helmetcrest (Oxypogon stuebelii) is a short-billed hummingbird found only at extremely high elevations in Colombia’s central Andes. Adult male’s green and blue beard, black and buff head pattern, and shaggy crest. Female and younger males lack the crest and beard and have more subdued coloration, but they are still recognizable from their large size and relatively tiny bill. Often seen feeding from or perching on Espeletia plants. Espeletia, also known as Frailejón, is native to high Andean grasslands; it is characterized by its short, trunk-like stem, large, elongated leaves, and small, yellow flowers.
Habitats & Distribution
The Buffy Helmetcrest is endemic to Colombia, specifically found in the páramo ecosystems of the central Andes. These high-altitude grasslands, typically situated between 3,800 and 4,800 meters above sea level, provide the cold and wet environment that this species thrives in.
Behaviours & Reproduction
This hummingbird species is known for its territorial behavior, often aggressively defending its feeding and breeding areas from intruders. The Buffy Helmetcrest builds small cup-shaped nests from plant fibers, moss, and lichens, usually positioned on rock ledges or among dense vegetation. Breeding typically occurs during the rainy season when food resources are more abundant.
Diet
This hummingbird primarily feeds on nectar from high-altitude flowering plants, especially those with tubular flowers. It also consumes small insects and spiders for protein.
Colors
Gray with buffy crest and purple beard
Fun Facts
Adapted to high-altitude environments with a higher concentration of hemoglobin in their blood.
Males fan out their elongated throat feathers during displays.
Aggressively defends feeding and breeding territories.
Conservation Status & Efforts
The Buffy Helmetcrest is currently classified as Endangered on the IUCN Red List. Habitat destruction, primarily due to agricultural expansion and burning of páramo vegetation, poses a significant threat to its survival. Conservation efforts are focused on habitat protection and restoration, as well as raising awareness about the importance of páramo ecosystems. Initiatives include creating protected areas and working with local communities to promote sustainable land use practices.
