The Story
This Golden-faced Tyrannulet (Zimmerius chrysops) was at Fincas Verdes in San Antonio, Tolima, Colombia when I photographed it. The female builds a domed nest with a side entrance, usually inside hanging moss on a tree trunk. The female alone incubates the two eggs, for about 17 days. It is highly vocal. The sexes have the same plumage. In Colombia it seldom joins mixed-species flocks. San Antonio lies in southern Tolima, about 109 km from Ibagué. Birds recorded around San Antonio include threatened species such as the Yellow-eared Parrot and the Spot-winged Parrotlet.
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 400. IUCN lists the Golden-faced Tyrannulet as Least Concern, with a stable population.
