Female Red-billed Emerald

The Story

This female Red-billed Emerald (Chlorostilbon gibsoni) perched on a twig near San Pablo de Borbur, in Boyacá, Colombia. The species lives only in Colombia and Venezuela, and the nominate subspecies is found in the Magdalena River valley. It usually feeds close to the ground, at small flowers that are less attractive to larger hummingbirds. Males have a mostly red lower mandible, the feature behind the name. IUCN lists it as Least Concern.

I used a Canon R5 with the RF 800mm f/11 plus the RF 1.4x extender for this one, at 1/90 sec, f/16, ISO 800, −0.5 EV. The Fura and Tena hills near town are promoted for hiking and birdwatching, with a local association running ecological tourism built around their ancestral legend.
