The Story
I photographed this Western Emerald (Chlorostilbon melanorhynchus) at the Jardín Botánico del Quindío in Calarcá, Quindío, Colombia, on July 17, 2018. The male has a glittering green crown with gold highlights and a steel blue tail. The female has a blackish face with a pale gray spot behind the eye. It readily accepts man-made habitats and is fairly common across its range. The garden’s butterfly house is a large open-air vivarium, home to more than 30 butterfly species native to Colombia. IUCN includes the Western Emerald in its assessment of Chlorostilbon mellisugus, which it lists 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 1/250 sec, f/5.6, ISO 800. The regional environmental agency, the CRQ, has also entrusted the garden with eight hectares of natural forest in the Barbas Bremen forest reserve, near Filandia and Circasia.
