Good pics. Over here on the west side we are just seeng the Anna's and Rufous.
Nice photos!On the color change, many birds have colors that occur from diffraction of the light off of the feathers rather than the feathers having color of their own (most often blues and reds). For example, a bluejay feather will look blue when in the sunlight, but if you hold the feather up so that the light passes through it, it will appear gray. The throat feathers of these hummingbirds is similar. When the light is not shining right on it they appear gray or black. This allows them to hide when in the shadows or display when out in the sun. Biology lesson of the day complete....
