A group of the birds is also sometimes called an “ostentation,” a “muster,” or even a “party.”

 

3. THEY’RE NOT BORN WITH THEIR FANCY TAIL FEATHERS.

The male peachicks don’t start growing their showy trains until about age three. In fact, it’s hard to tell the sex of a peachick because they’re nearly identical to their mothers. At around six months, the males will begin to change color 

4. THEY DON’T HAVE TO BE KILLED FOR THEIR FEATHERS.

Luckily, the peacocks shed their train every year after mating season, so the feathers can begathered and sold without the birds coming to any harm. The average lifespan of a peacock in the wild is about 20 years.

5. THEY CAN FLY, DESPITE THEIR MASSIVE TRAINS.

A peacock’s tail feathers can reach up to six feet long and make up about 60 percent of its body length. Despite these odd proportions, the bird flies just fine, if not very far.

Thanks to selective breeding, it’s common for captive peafowl to buck the iridescent trend for all white feathers. This is called leucism, and it’s due to a genetic mutation that causes loss of pigmentation. These peafowl are often mistaken for being albino, but instead of having red eyes, animals with leucism retain their normal eye color.

7. PEACOCKS WERE A DELICACY IN MEDIEVAL TIMES.

The birds were plucked, roasted and then re-dressed in their feathers to appear in their original live state on the dinner table. Here’s the presentation instructions from one recipe:

“wynde the skyn

wit the fethurs and the taile abought

the body, And serue him forthe as he

were a-live”

The birds may have looked beautiful, but they reportedly tasted terrible. “It was tough and coarse, and was criticized by physicians for being difficult to digest and for generating bad humors,” writes Melitta Weiss Adamson in her book Food in Medieval Times.

These birds aren’t just nice to look at, they’re also clever, according to one recent study.

When peafowl mate with peahens, they give out a loud “copulatory call.” Canadian researchers Roslyn Dakin and Robert Montgomerie discovered that the birds can “fake” this call to attract more females. As the BBC’s Ella Davies put it, “By pretending they are mating when they are not, the birds could convince females they are more sexually active—and therefore genetically fitter—than their rivals.”

In fact, one-third of the calls heard by researchers were fake, and the birds that made them scored the most hookups. Sneaky, sneaky.

9. THEIR FEATHERS ARE COVERED IN TINY CRYSTAL-LIKE STRUCTURES.

What makes the peacock’s feathers so brilliant? Microscopic “crystal-like structures” that reflect different wavelengths of light depending on how they’re spaced, resulting in bright fluorescent colors. Hummingbirds and shimmering butterflies have mastered a similar visual effect on their own wings.
