The Story
This Long-tailed Sylph (Aglaiocercus kingii), of the subspecies emmae, was at the Recinto del Pensamiento in Manizales, Caldas, Colombia when I photographed it. The Long-tailed Sylph feeds on nectar and insects, usually hovering at flowers but sometimes clinging to them or piercing the base of a flower to rob nectar. It catches insects by flying out from a perch. The reserve’s trails pass a hummingbird viewpoint, a butterfly house, an orchid forest and the Pabellón Zeri, built of guadua and regional woods. IUCN lists the Long-tailed Sylph as Least Concern, with a decreasing population.
I made this frame with a Pentax K-1 and the HD Pentax-D FA 150-450mm f/4.5-5.6, at 1/200 sec, f/7.1, ISO 100, +1 EV. The reserve belongs to the Comité Departamental de Cafeteros de Caldas and is run by the Corporación para el Desarrollo de Caldas to promote nature tourism in Manizales.
