Male hummingbirds are usually bright and have various colours to attract female hummingbirds. The different colours are the result of prism like cells which are located at the top of the humming bird and the pigmentation of the feathers. The changing colours are due to the combination of pigmentation and refraction. The cells in the feathers act as diffraction grating. Therefore just by changing position, the humming bird would seem as if its changing colour from dark green to red.
One example to understand this concept would be oil in water would have various colurs when sunlight falls on it.

Color First Peck Frequency Blue 16 Green 9 Yellow 6 Red 3 Birds use color to select and avoid certain types of food. The authors of a particular article studied the pecking behavior of 1-day-old bobwhites. In an area painted white, they inserted four pins with different colored heads. The color of the pin chosen on the bird's first peck was noted for each of 34 bobwhites, resulting in the accompanying table. Do these data provide evidence of a color...

1. Do "early birds" (people who tend to get up early in the mornings) live longer than "night owls" (people who tend to stay up late at night)? A recently published study in Chronobiology International surveyed a representative sample of more than 150,000 UK citizens between the ages of 38 and 73, and asked them whether they identified as "night owls" or "early birds," and to what degree (moderate or definite). The re Ohe data are then recorded whether leveloped...
