This used to be the Green Violet-ear Hummingbird, which distinguished it from the closely related Brown Violet-ear of slightly lower elevations, but in the wisdom of the bird name gods, it is now the Lesser Violet-ear. (Can it be long before the Brown Violet-ear becomes the Greater Violet-ear? Who knows.) The Lesser Violet-ear was by far the most common hummingbird around Savegre Mountain Resort and the Batsu Garden in San Gerardo de Dota this year. You can see in the first image where they get the Violet-ear name. They often flare the ear patch in a dominance display. Each of these images deserves a full screen view. All were taken at Batsu Garden on the mountain side above Savegre Mountain Resort. Sony RX10iv at 600mm equivalent. My birds and wildlife modifications of Program mode. Processed in Polarr. (In the last two, there was a visually distracting over-exposed leaf in the bottom right corner which I edited out in Touch Retouch.)
