9 Bizarre Bird Mating Rituals

Bees do it, and birds definitely do it—in all kinds of crazy ways. Here are nine birds and their mating rituals.

1. Frigatebird

Male frigatebirds have red kidney-shaped pouches on their chests that they inflate like balloons to attract girls. During mating season, the male sits on a nest and gyrates his puffed-up chest at the females flying overhead. When a female sees a male she likes, she lands beside him. However, copulation is often interrupted when other jealous males jump on the chosen partner and try to puncture his red balloon.

2. Flamingo

When choosing a mate, flamingos dance in a big group. They stretch their necks and flip their heads back and forth while taking tiny, mincing steps. Then they break off in pairs to breed. It’s pretty much the greatest thing ever.

3. Duck

Wild with Pants

Ducks have a reputation for being monogamous, but the reality is more gruesome, as the females are often gang raped by the males. This behavior is so ingrained in ducks that the female's oviduct (vagina) has sacs and dead ends that can hold and expel unwanted sperm. Scientists theorize that she can unblock her oviduct if so inclined, meaning that she usually ends up with the desired drake's ducklings.

Incidentally, the Argentine Lake Duck has the longest bird penis, which is corkscrew shaped and 17 inches long.

4. Emperor Penguin

This mating ritual of the Emperor Penguin starts miles apart. The males and females walk 30 to 70 miles to inland Antarctica and meet at a breeding site. Then they stand in a crowd and the males “bugle” for the females, who recognize their mates’ voices. They take a waddle around the group, bow deeply to one another, nuzzle, and make loving noises before mating.

5. White-Fronted Parrot

White-Fronted Parrots kiss by putting their beaks together and touching each other’s tongues. Then the male vomits into the female’s mouth. To the female, this is a tasty treat that gets her in the mood.

6. Hedge Sparrow

Science isn't Everything

The Hedge Sparrow is monogamous—mostly. The female will sometimes keep a second male on hand, who lurks in the bushes waiting for her mate to turn his back. When he does, she lets him copulate with her, a process that’s more like a bumping of genitals. Then things get weird: When the first mate comes back, she displays herself to him and he pokes at her genitals until the other male’s sperm spurts out. Then the two birds have sex, ensuring that it’s (probably) her mate’s egg in the nest. Why do this? Both the mate and the misinformed adulterer will help the female feed the chicks.

7. Albatross

Albatrosses start out with mutual grooming, each tenderly preening the other bird's feathers. Then they launch into a mating dance where they alternate between tapping their beaks, opening their mouths, and looking at the ground. To a casual observer, it looks like the birds are jousting, their beaks rattling together like castanets.

8. Blue Manakin

Not all males compete against each other for mates. In the case of the Blue Manakin, an alpha male forms a team of birds to help him attract females. When an interested female appears, the team begins flying around her, flapping their wings and making a buzzing noise while she looks on in awe. The alpha bird stops the acrobatics with a commanding call and, if the female liked the show, she’ll mate with him. The other males don’t get much out of this arrangement, except to compete for the alpha’s place if something happens to him.

9. Grebe

Grebes, a kind of water bird, perform a bird version of ballet before mating. They start out mimicking each other’s movements and then rise out of the water and run along its surface, flapping their short wings and tripping along in perfect unison. At the end, they dive under the water and come up with grass from the bottom as if to say, "Here is what we will use to make our nest."

Slow Motion Is the Only Way to Appreciate a Chameleon’s Lightning-Fast Tongue

From the unusual way they walk, to their ability to change color, the evolutionary adaptations of chameleons are pretty bizarre, and some of them remain mysterious even to scientists. Their super-powered tongues, for instance, can dart out so quickly that the movement can barely be seen with the naked eye. But modern high-speed cameras have enabled researchers at the University of South Dakota to observe this appendage at work like never before. The video below, shared over at The Kid Should See This, includes some of that groundbreaking footage, and it's pretty amazing to watch.

Shooting at 3000 frames per second, the camera was able to capture every split-second aspect of the chameleon's tongue strike. Slowed down, the video allows you to see how every component of the process works in harmony: First, muscles in the lizard’s tongue contract like the string of a bow. Then, when that tension is released, the bony base of the tongue shoots forward, pushing the sticky, elastic part toward the chameleon’s prey.

According to Christopher Anderson, one of the scientists who conducted the high-speed camera research, larger chameleons can catapult their tongues forward at distances of one to two times their body length. For smaller chameleons, this distance can reach up to two and a half times their body length. “Small chameleons need to be able to eat more food for their body size than large chameleons,” he tells bioGraphic in the video, “and so by being able to project their tongues proportionately further than these large species, they basically are opening up additional feeding opportunities to themselves that they wouldn’t have if they had a shorter tongue.”

There May Be an Ancient Reason Why Your Dog Eats Poop

Dogs aren't known for their picky taste in food, but some pups go beyond the normal trash hunting and start rooting around in poop, whether it be their own or a friend's. Just why dogs exhibit this behavior is a scientific mystery. Only some dogs do it, and researchers aren't quite sure where the impulse comes from. But if your dog is a poop eater, it's nearly impossible to steer them away from their favorite feces.

A new study in the journal Veterinary Medicine and Science, spotted by The Washington Post, presents a new theory for what scientists call "canine conspecific coprophagy," or dogs eating dog poop.

In online surveys about domestic dogs' poop-eating habits completed by thousands of pet owners, the researchers found no link between eating poop and a dog's sex, house training, compulsive behavior, or the style of mothering they received as puppies. However, they did find one common link between the poop eaters. Most tended to eat only poop that was less than two days old. According to their data, 85 percent of poop-eaters only go for the fresh stuff.

That timeline is important because it tracks with the lifespan of parasites. And this led the researchers to the following hypothesis: that eating poop is a holdover behavior from domestic dogs' ancestors, who may have had a decent reason to tuck into their friends' poop.

Since their poop has a high chance of containing intestinal parasites, wolves poop far from their dens. But if a sick wolf doesn't quite make it out of the den in time, they might do their business too close to home. A healthier wolf might eat this poop, but the parasite eggs wouldn't have hatched within the first day or two of the feces being dropped. Thus, the healthy wolf would carry the risk of infection away from the den, depositing the eggs they had consumed away in their own, subsequent bowel movements at an appropriate distance before the eggs had the chance to hatch into larvae and transmit the parasite to the pack.

Domestic dogs may just be enacting this behavior instinctively—only for them, there isn't as much danger of them picking up a parasite at home. However, the theory isn't foolproof. The surveys also found that so-called "greedy eaters" were more likely to eat feces than dogs who aren't quite so intense about food. So yes, it could still be about a poop-loving palate.

But really, it's much more pleasant to think about the behavior as a parasite-protection measure than our best pals foraging for a delicious fecal snack.
