Glowing Puffleg

A brilliantly colored puffleg hummingbird of the northern Andes from Colombia to southern Ecuador, glowing pufflegs display vivid iridescent green plumage that glows with an almost luminescent quality in bright light — inspiring the species' descriptive common name. Found in humid montane forest at elevations of 1,800–3,500 meters. Males have characteristic white leg puffs and a shimmering violet-blue tail. They are important pollinators of high-Andean flowering plants. Listed as Least Concern.

Long-tailed Sylph

One of the most strikingly ornamented hummingbirds, male long-tailed sylphs have iridescent green plumage and dramatically elongated, ribbon-like outer tail feathers reaching up to 22 cm — over three times the body length. Found in Andean cloud forests of Colombia and Venezuela, they inhabit humid montane forest between 1,400–2,800 meters elevation. Males perform elaborate display flights to attract females. Their extravagant tails are a classic example of sexual selection via female preference.
