Some lovely hummingbird images…Janet.
Male Anna’s Hummingbird. Gilbert Water Ranch, Gilbert, Arizona. December 2015.
I saw a few hummingbirds when I went to Arizona last December. And when I looked through my photos, they were all male Anna’s hummingbirds. Male Anna’s have fancy magenta feathers on both their crown and throat. The colour is not a pigment, but a structural property of the feathers. When light hits the feathers at a certain angle, they appear magenta because this is the wavelength that is reflected. The magenta waves are also amplified by the feather surface, which is composed of layers of tiny air bubbles. When light meets the feathers at other angles, no light is reflected so they appear black. I didn’t photograph any hummingbirds whose crown and throat feathers were angled for full magentic splendor. Maybe some other time! You can read more about hummingbird iridescence on the Sibley Guides website.
