（单词翻译）

 The glittery blues1 seen on bird wings are often caused not by pigment2, but by the way light waves interact with the feather. Physicists3 call this “structural4 color”. Because of the layered structure of the feather, light waves entering it bounce back at different times and thus collide, or “interfere” with each other. Certain wavelengths5 get cancelled out while others become reinforced. The reinforced colors that come back strongly to your eye are mostly in the blue range. The result is that eye-catching display of blues. As it turns out, there aren’t many blue pigments6 used by birds in general. So any time you see blue or purple on a bird’s wing, you can suspect that at least some of it is structural color. Especially if it’s got that razzle-dazzle effect.
