Refusing Overthinking: Trusting Yourself
D
An Anna’s Hummingbird (蜂鸟) was seen in the forest in California recently. As it moved its head, its feathers changed colors in the sunlight. The Anna’s Hummingbird is a small hummingbird found along the west coast of North America. The male Anna’s Hummingbird has colourful feathers on its head and throat, which can appear red, pink, orange, or green. This has led to the assumption that the bird can actively（主动地）change the colour of its feathers, but it is actually not the case.
The colour shifts we see are caused by the structure of the feathers, not by changes to the actual colouring of the feathers. The tiny structures on the surface of the feathers interact with light waves to produce certain colors. Anna’s Hummingbird feathers have tiny structures called melanosomes ( 黑色素体) that look like stacked flat discs ( 圆片). These disc stacks are super thin, close to the size of the light waves we can see. When sunlight hits these discs, the light waves bounce and interact with each other. Some colors get brighter, while others cancel out, creating shining rainbow effects — similar to how soap bubbles. This “light dance” is why hummingbird feathers look so colourful!
Unlike Anna’s Hummingbirds, some birds change the colour of their feathers in a different way. For example, the Western Tanager has yellow feathers on its head and body. During molting ( 蜕毛), it can absorb the yellow colour to display an orange-red colour underneath. Thus, while Anna’s Hummingbirds rely purely on the structures of feathers, other birds actively control the colour spread and feather movement to produce changeable feathers.
The special feather structures in Anna’s Hummingbirds allow us to witness the diversity and wonder of the world. Next time you observe an Anna’s Hummingbird in the sun, watch closely as its throat seems to flash in rainbow colors. But remember — this magic is happening in the structures through physics(物理学），not biology.
What can we learn about Anna’s Hummingbirds according to the passage
