The Story
This Purple-backed Thornbill (Ramphomicron microrhynchum) was at Murillo, Tolima, Colombia when I photographed it. It is found in Bolivia, Colombia, Ecuador, Peru and Venezuela. It has often been seen robbing nectar through holes that flowerpiercers have made in flowers. It also feeds on insects caught on the wing and gleaned from flowers. Both sexes have a white spot behind the eye. Cortolima lists Murillo among Tolima’s birding routes. Murillo, at about 3,000 meters, is the highest town in Tolima, close enough to Nevado del Ruiz that the volcano is easy to see.
I made this frame with a Pentax K-1 and the HD Pentax-D FA 150-450mm f/4.5-5.6, at 1/320 sec, f/5.6, ISO 3200. IUCN lists the Purple-backed Thornbill as Least Concern, with a decreasing population.
