I love it when I can capture the light glinting off of a hummingbirds gorget like I did yesterday afternoon with a male Rufous Hummingbird. It was simply gorgeous like the hummingbirds throat was on fire. The word gorget comes from the time when a knight-in-armor wore a metal collar or gorget to protect his throat during battle. In hummingbirds the bright intense glint is the result of iridescence, rather than colored pigments in the feathers. A hummingbird's gorget feathers contain very tiny, thin, layers of “platelets,” set like overlapping tiles against a dark background. The light waves reflect and bounce off the tiles, creating color in the manner of sun bouncing off droplets of water in a rainbow. Hummingbirds can angle their gorget feathers too turn the irridescence on and off like a light bulb. It is amazing when they turn towards you and flash their feathers to on! Blessings upon your day, chris All images created with a Canon 7D and a Tamron 150-600mm lens. Fill flash was provided by a Canon 500EX flash set to high speed sync.
