The Story
This is a Long-tailed Sylph (Aglaiocercus kingii) that I photographed at the Río Blanco reserve near Manizales, Caldas, Colombia on June 24, 2017. It lives in open country such as scrub, clearings, forest edges and gardens, between about 900 and 3,000 meters. Andean populations move seasonally between lower and higher elevations. The male is 16 to 19 centimeters long, including outer tail feathers that alone measure about 12 centimeters. The Río Blanco reserve covers 4,932 hectares of cloud forest on the Central Andes, about 3 kilometers northeast of Manizales.
I photographed it with a Canon EOS 70D and the EF400mm f/5.6L USM, at 1/1000 sec, f/6.3, ISO 1000. IUCN lists the Long-tailed Sylph as Least Concern with a decreasing population, and Río Blanco, a protected forest reserve managed by the regional authority Corpocaldas, supplies about 35 percent of the drinking water of Manizales.
