When you see a flash of color, as a hummingbird zooms past it seems to be a color flash from the human eyes. As I looked at this photo,some dark colors but some very vivid,I had forgotten the reason for this, so I did some research.Most birds attribute their color to pigmentation,but the hummingbird is said to have special cells within the top layer of the feathers. These cells diffract the light into different wavelengths(i.e. producing different colors),depending on the viewing angle, only specific colors,at that angle, are seen by the human eye.Guess I have a lot more questions as to why this specie of bird was made this way? Nature is fascinating!!!!!!

Like to photograph a variety of subjects,the Bullfrog was well hidden and hard to see in the water. The light colored butterfly in geranium flower also is partial hidden. Don't know specie of butterfly,we used to call them Cabbage butterflies ,back on the farm.
