It is not that easy to capture all the nuances of the plumage of a Green-throated sunbird. As with many other sunbirds, the colors change depending on the light and angle. In some positions, the male appears to be completely black. In other positions, the shimmering forehead spot is visible, usually green, but as in the picture, it can shift to blue and violet. A small and narrow cheek spot also shines in green. In most of the range, such as here in Uganda, the bird also has a greenish-shiny chin. In the picture, you can also guess (but barely see) the narrow, violet border band under the chin spot.
