Appearance: The White-whiskered Hermit is a medium-sized hummingbird with distinctive features. It has a white or light-colored supercilium (eyebrow) and long, white or buff-colored malar stripes (whiskers) on its cheeks, giving it its name. The upperparts of the bird are typically green, and the underparts may vary from buffy to cinnamon in color. These birds have a long, slightly curved bill adapted for feeding on nectar from flowers and a dark tail.

Habitat: White-whiskered Hermits are commonly found in humid forests, including montane forests, cloud forests, and forest edges in Colombia. They prefer habitats with dense vegetation and an abundance of flowering plants that provide a nectar food source. These hummingbirds may also occur in secondary growth, plantations, and gardens near forested areas.

Behavior: White-whiskered Hermits display typical hummingbird behaviors like feeding on nectar from flowers using their specialized bills. They are agile fliers with the ability to hover and access nectar from a variety of flower species. These birds may also supplement their diet with small insects and spiders for protein.

Breeding: The breeding behavior of the White-whiskered Hermit likely involves courtship displays by males to attract females. Nests are usually cup-shaped and constructed using plant fibers, moss, and spider silk, positioned on tree branches or vines. Female White-whiskered Hermits generally incubate the eggs and care for the young, with both parents participating in feeding and raising the chicks.

Conservation Status: The White-whiskered Hermit is currently categorized as "Least Concern" by the International Union for Conservation of Nature (IUCN).
