With the late morning sun to my back, the gorget feathers flashed like signal beacons, the iridescence looking more golden than ruby colored. Definitely worth trying to capture in a photo. After some patient waiting, I caught some images of a male showing a nice "flash" in the gorget. Note the black chin under the bill that distinguishes this common species from the Broad Tailed Hummingbird which is rare here in Georgetown.
I used a Canon 60Da camera and a Canon EF 100-400mm f/4.5-5.6L IS lens. With the lens fully extended and the camera set to ISO-400, I adjusted the aperture to f/7.1 giving me enough depth-of-field to focus the full bird but keep the rock wall, about 3 ft behind the feeder, out of focus. In this light, the shutter speed of 1/1600s was adequate for perched poses. I set the camera to high-speed burst imaging to assist in getting some shots that had interesting poses. I decided not to use a flash to keep from creating either "steel eye" or "feather sheen". Like some earlier pictures, I can see details of the yard behind me reflected in the the bird's eyes! However, not using the flash required some post-processing work to raise the brightness of the head shadows and reduce the noise in those dim parts of the image.
