Why different species start looking exactly the same

Is it better to stand out from the crowd or be similar to the background? For birds, the answer is complicated. While peacocks(孔雀) show off their brightly colored feathers to attract mates and ward off predators(捕食者), other birds find it     1     to hide themselves by imitating the looks of other birds.

Groups of birds flying together often come from the same species, making it hard to     2     one from another. However, some groups of birds including two or more species take on similar     3    , which is an uncommon phenomenon. “They all share random features, like feathers on head or yellow bellies(腹部), which makes them almost     4    . You can’t really tell them apart without looking at their     5    .” says Scott Robinson, a famous scholar. His new study suggests     6     another bird’s appearance is not a coincidence(巧合) but rather an evolutionary method to increase their chances of survival. Looking like a bird from a dominant species helps reduce attack from other members and appear more     7     to potential predators.

“In imitation, you often want to look like something because there’s an advantage to being that other thing. You want species to think you’re     8     or low-profitable target.” says Rebecca Kimball, a professor of biology. “In grouping birds, one idea is that this has more to do with a predator’s ability to     9     a target. When there are a group of birds moving around, it may be easier for predators to identify an individual that has a distinct color pattern.”

While it may not seem like it at first, imitating other birds is helping to create more     10     species. Not only do birds imitate more than one species as they grow up, but their appearance varies over time.

If you have ever had a cat, or have watched one of the many funny cat videos online, you'll know that cats have a mind of their own. A lot of the things they do are hard to understand—they like to climb up tall furniture,    1    themselves in small spaces and attack small objects for no reason at all.

Now scientists have managed to    2    out what exactly is going on in the brains of our little friends.

According to Tony Bufflington, a veterinarian and professor at Ohio State University in the US, cats' strange behavior    3    comes from their way of life back in the wild.

"Cats today still have many of the same instincts that    4     them to live in the wild for millions of years," he said in a TED Talk. "To them, our homes are their jungles."

In the wild, cats are hunters. Their bodies and great    5    abilities allow them to climb to high spots to better look at the environment. Even though they don't have to hunt anymore in human houses, they still keep the old habit of     6    the living room from, for example, the top of the refrigerator.

cats' hunting instinct is also what makes them    7    small things like keys and USB drives. In the wild, they hunt whatever they can get, and most of the animals they kill are small.

However, cats can also be prey. This explains why they like to stay in small spaces like drawers or washing machines—they are    8    , or they think they are doing so, from more dangerous animals. This is also why cats    9    a clean litter box; a smelly one could easily show enemies where they are.

But knowing how cats' minds work is not only useful for better understanding them. It may also help cats' owners to better meet cats' needs.

For example, owners could try to make climbing easier for cats by moving their furniture around. They could also use "food puzzles" to make eating feel more like hunting instead of just feeling    10    .

Magical Creatures: AN APPRECIATION OF AUTUMN MOTH (蛾)

Moths seem to have a bit of a bad reputation: to some they are ill indications or something scary, to others they are dull in comparison to our well-loved butterflies. But moths are an essential part of a(n)     1    , and important food sources for species like birds and bats. And for me, moths are far from dull.

My first meeting with an Angle Shades moth was nearly a non-encounter. I almost passed by without noticing it, thinking it was a fallen leaf on a fence post. But there was something about it that stopped me in my tracks. Its angular shape perhaps? Or the way it sat,     2    , despite the breeze. Closer     3     revealed cream and buff shell-shaped wings, painted with triangles of light pink and brown. Suddenly, it transformed from a(n)     4     leaf into a living thing before my eyes. I’ve been fascinated ever since.

The Canary-shouldered Thorn, with its hairy buttercup-coloured body and yellow and orange wings, reminds me of a fallen silver birch (白桦树) leaf. A night-flyer, it favours gardens and woodlands, and is often drawn to     5     light, meaning that your torch beam may be attracting moths as well as lighting your way in the dark. It’s also worth double-checking any leaves in farm houses, as these sheltered spots are a favourite hiding place of another overwintering     6    : the Herald moth. This elegant creature’s beautiful wings look as though they’ve been     7     by hand and painted with bronze.

There’s more to these imitators than fallen leaves. The Green-spotted Crescent, which     8     disappears on rough branches, has metallic green spots integrating with the moss (苔藓). Maybe I’ve already     9     crossed paths with one, though. As we dig out our big coats and slip on boots for walks beneath branches, how many moths are we missing? These clever creatures aren’t bad indications, but     10     parts of nature, with a gift for fancy-dress.
