Red-tailed comet

The red-tailed comet is a hummingbird species primarily found in the mountainous regions of South America, specifically in Bolivia and Argentina. They thrive in high-altitude environments, including the Andes slopes and scrublands. Birdwatchers often spot them in these areas due to the male's brilliantly colored, long tail.

Taxonomists classify the red-tailed comet (Sappho sparganura) as the sole member of its genus due to its unique morphological traits, such as the male's extraordinarily long, forked tail. The bird was first officially described by English zoologist George Shaw in 1812. Its distinct physical separation from other hummingbirds warranted its own genus, Sappho.

Like most hummingbirds, the red-tailed comet feeds primarily on high-sugar nectar from native flowering plants in the Andean regions. They use their specialized bills to extract nectar while hovering in mid-air. They will also occasionally catch small insects on the wing to supplement their diet with necessary proteins.

The male red-tailed comet is famous for its spectacular, elongated, iridescent tail feathers that range in color from shimmering purple to fiery red. These extremely long tail feathers trail behind the bird during flight and are used in elaborate mating displays. This striking visual feature is what inspired its classification by George Shaw.
