The ruby colored throat feathers of the male are very odd in that they show up different depending on the angle of the shot and the lighting. Sometimes the color appears to be black and then other times only partially ruby colored. This one is a good close up that shows the real color and the details of the feathers.
This image shows how sometimes the ruby colored neck show up as Black.
