Yesterday, I watched a hummingbird at the feeder, curious to note that each time he moved his head, the color of his throat changed – from the ruby red of his name, to greenish, to orange, to brown. Was that really happening or was it the angle I saw the bird, a reflection from my window or the glass container holding the sugar nectar?
The photos below are an even better example of the throat color changing. Is it live or is it Memorex?
Any bird brains out there know?
