Green-fronted Lancebill

A medium-sized hummingbird with a distinctively long, slightly upturned bill, green-fronted lancebills inhabit the mid-strata of humid montane cloud forest in the Andes from Costa Rica through Colombia and Ecuador to Bolivia at elevations of 1,000–2,400 meters. Their elongated bill is specialized for probing the long tubular flowers of Centropogon and other Andean bell-flowers inaccessible to shorter-billed hummingbirds. Males are glittering green throughout; females have white-spotted underparts. 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.
