The Story
This Buff-rumped Warbler (Myiothlypis fulvicauda) was at Fincas Verdes in San Antonio, Tolima, Colombia when I photographed it. Single birds and pairs hop along the forest floor and fallen logs, constantly pumping and wagging their tails. It forages along streams, wet patches of forest floor and puddles on forest paths. Pairs defend a long, narrow territory along a watercourse all year. Its nest is a bulky domed cup with a side entrance. Birds recorded around San Antonio include threatened species such as the Yellow-eared Parrot and the Spot-winged Parrotlet. San Antonio lies in southern Tolima, about 109 km from Ibagué.
I made this frame with a Pentax K-1 and the HD Pentax-D FA 150-450mm f/4.5-5.6, at 1/100 sec, f/5.6, ISO 6400, +1 EV. IUCN lists the Buff-rumped Warbler as Least Concern, with a decreasing population.
