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.

Rusty-faced Parrot

A medium-sized parrot of the high-altitude cloud forests and Andean slopes of Colombia and Venezuela, rusty-faced parrots have green plumage with a distinctive orange-rufous face and forehead. They inhabit humid mountain forests between 1,500–3,000 meters and are little studied due to their remote, steep habitat. Listed as Vulnerable due to ongoing deforestation of Andean cloud forests. They move seasonally with food availability across forested ridges.
