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."

Watch a School of Humpback Whales 'Fish' Using Nets Made of Bubbles 

Just like humans, humpback whales catch many fish at once by using nets—but instead of being woven from fibers, their nets are made of bubbles.

Unique to humpbacks, the behavior known as bubble-net feeding was recently captured in a dramatic drone video that was created by GoPro and spotted by Smithsonian. The footage features a school of whales swimming off Maskelyne Island in British Columbia, Canada, in pursuit of food. The whales dive down, and a large circle of bubbles forms on the water's surface. Then, the marine mammals burst into the air, like circus animals jumping through a ring, and appear to swallow their meal.

The video offers a phenomenal aerial view of the feeding whales, but it only captures part of the underwater ritual. It begins with the group's leader, who locates schools of fish and krill and homes in on them. Then, it spirals to the water's surface while expelling air from its blowhole. This action creates the bubble ring, which works like a net to contain the prey.

Another whale emits a loud "trumpeting feeding call," which may stun and frighten the fish into forming tighter schools. Then, the rest of the whales herd the fish upwards and burst forth from the water, their mouths open wide to receive the fruits of their labor.

Big Questions
Why Do Dogs Love to Dig?

Dog owners with green thumbs beware: It's likely just a matter of time before Fido turns your azalea bed into a graveyard of forgotten chew toys. When dogs aren't digging up your prized garden, they can be found digging elsewhere in your yard, at the beach, and even between your couch cushions at home. But what exactly is behind your dog's drive to turn every soft surface he or she sees into an excavation site?

According to Dr. Emma Grigg, an animal behaviorist and co-author of The Science Behind a Happy Dog, this behavior is completely normal. "When people say 'why do dogs dig,' the first thing that always comes to mind is 'well, because they're dogs,'" she tells Mental Floss. The instinct first appeared in dogs' wolf ancestors, then it was amplified in certain breeds through artificial selection. That's why dogs that were bred to hunt rodents, like beagles and terriers, are especially compelled to dig in places where such animals might make their homes.

But this tendency isn't limited to just a few specific breeds. No matter their original roles, dogs of all breeds have been known to kick up some dirt on occasion. Beyond predatory urges, Dr. Grigg says there are two main reasons a dog may want to dig. The first is to cool off on a hot day. When stuck on an open lawn with little to no shade, unearthing a fresh layer of dirt untouched by the sun is a quick way to beat the heat.

The second reason is to stash away goodies. Imagine your dog gets bored with chewing his favorite bone but knows he wants to come back for it later. Instead of leaving it out in the open where anyone can snatch it up, he decides to bury it in a secret place where only he'll be able to find it. Whether or not he'll actually go back for it is a different story. "There's a disconnect with modern dogs: They know the burying part but they don't always know to dig it up," Dr. Grigg says.

Because digging is part of a dog's DNA, punishing your pet for doing so isn't super effective. But that doesn't mean you should stand idly by as your yard gets turned inside-out. When faced with this behavior in your own dog, one option is to redirect it. This can mean allowing him to dig in a designated corner of the yard while keeping other parts off-limits, or setting up a raised flowerbed or sandbox especially to satisfy that urge. "You can get him interested in the area by burying a couple bones or some interesting things in there for him to dig," Dr. Grigg says. "I like the idea of buried treasure."

If your dog's motive for digging is more destructive than practical, he may have an energy problem. Dogs require a certain amount of stimulation each day, and when their humans don't provide it for them they find their own ways to occupy themselves. Sometimes it's by chewing up shoes, toppling trash cans, or digging ditches the perfect size for twisting ankles. Fortunately, this is nothing more walks and playtime can't improve.
