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.
