9 Awesome Facts About The Reproductive Lives Of Birds And Bees

Here are some awesome facts you might not have known about the reproductive lives of our feathered and stinger-ed friends – Birds and Bees.

Most Male Birds Don’t Have Penises

Ninety-seven percent of bird species don’t grow penises. But why? A 2013 study that compared chickens (who don’t have penises) with ducks (whose penises are “large and elaborately coiled,” according to one description) found that a sort of cell suicide, called “programmed cell death,” is to blame. A theory as to why birds lost their penises is that female birds may have preferred it, since, as The Scientist put it, birds of this disposition “are less capable of unwanted advances and thus give female birds more choice in which males father their young.”

Birds Get Romantic With a “Cloacal Kiss’

For those birds without penises, mating takes the form of the “cloacal kiss.” The cloaca is an orifice found on the rear of both bird sexes. It serves a whole bunch of functions: pooping, peeing, egg-laying, and sperm ejection. When it’s time to mate, the cloaca will swell. The male and female birds will then rub their swollen cloaca together, once the male hops atop the female and the female moves her tail out of the way. The ensuing “kiss,” or sperm transfer, is, generally speaking, vanishingly brief.

Horny Male Birds Put On A Great Show


For birds whose mating requires female consent, males may engage in elaborate mating rituals to lure prospective sex partners.

Ducks Have Penises That Are Shaped Like Corkscrews


Duck penises are long counterclockwise twists, while similarly-shaped duck vaginas twist in the opposite direction.

Some Female Birds Are Polyamorous

Bird society is really interesting. Most birds are explicitly polyandrous, meaning the female birds take on multiple male lovers. Female wattled jacanas, for example,  mate with many males, who then incubate the eggs and raise the chicks, even when paternity isn’t clear. This setup is a rare state of affairs, as it were, both in and out of the bird world.

Good Thing Baby Penguins Are Sooooo Cute After That Long Incubation

Emperor penguins have one of the bird world’s longest incubation periods. Females lay one egg in May or June (wintertime in Antarctica), then skedaddle to look for food. The male penguins incubate the eggs — on their feet, not eating, in temperatures that can go down to -76 degrees Fahrenheit — for 65-75 days. Mums come back and regurgitate the food they’ve hunted while away to feed their newly-hatched chicks.

Queen Bees Take A ‘Mating Flight’ Early In Their Lives, Late In A Drone’s Life


A week into life, new queen bees go on “maiden flights” (also called “mating flights,” “virgin flights” and “wedding flights”). While they’re flying about, they will mate with a dozen or so male bees, called drones. Each drone sticks his endophallus, or bee penis, into the queen’s sting chamber (that’s not a euphemism; that’s what it’s called). Then that’s that for the drone — some describe bee mating as a drone’s “sexual suicide” — but just the beginning for the now-inseminated queen.

Drones Have No Fathers

There are three kinds of bees in a hive: a queen, worker bees (who are female) and drones (who are male, and make up a small percentage of the hive population). Drone bees are produced when a queen bee lays unfertilized eggs. That’s right, unfertilized eggs — which means that drones, whose main purpose is to mate with the queen and then die, are themselves fatherless.

Regicide Is A Fact Of Life For Bees

During her mating flight, the queen bee will mate with lots of drones. She’ll then store their sperm inside her body for the rest of her life (up to a couple of years), laying thousands of eggs — fertilized and not — to replenish the colony. Drones hatch from unfertilized eggs. Worker bees hatch from fertilized eggs; there are more worker bees than any other type in the hive, and they do almost all the work. Queen bees also hatch from fertilized eggs, but ones that have been fed royal jelly by workers, once the original queen’s fertility is failing. The first queen to hatch will often kill the other developing queens. Queens are killed in various other circumstances as well; when worker bees kill a queen bee as a group, it’s called “balling.”.
