Long-tailed Sylph

The Story

I made this photo of a Long-tailed Sylph (Aglaiocercus kingii), of the subspecies emmae, at Finca Alejandría at Km 18 above Cali, Valle del Cauca, Colombia. The male builds the nest, a bulky dome of moss and plant fibers with a side entrance. It lives between about 900 and 3,000 meters and has a complex pattern of movements. Finca Alejandría sits in cloud forest at Km 18 on the road from Cali to Buenaventura, and it is an eBird hotspot with more than 340 bird species recorded, about 40 of them hummingbirds. IUCN lists the Long-tailed Sylph as Least Concern, with a decreasing population.

I used a Pentax K-1 with the HD Pentax-D FA 150-450mm f/4.5-5.6 for this one, at 1/200 sec, f/5.6, ISO 800. The finca has run as a birdwatching ecotourism project for more than twenty years, and visitors’ support helps keep its feeders stocked with bananas, sugar and water.
