A common hummingbird in California. About 3.5" (9 cm) in length
Most of the bird's color is not from pigment but from refraction, so the same area (the throat for example) can
appear black when incident light if from one angle but iridescent  red when the light is from a different angle.

Celestron C6 (150mm aperture, 1500mm FL, a small astronomical telescope)  and Canon XTi
The bird was about 30 meters from the camera
Note the imaged has been binned (reduced in size) to about 35% of original image size to fit webpage.
The image of the head/eye give you an idea of the detail in the original image.
