Monogamy, which refers to having one lover at a time,  frequently arises in the animal kingdom when offspring require extensive parenting. Some monogamous species form stable bonds for just one season, which is referred to as serial monogamy. Others may form pair bonds for multiple seasons or even life.

Celebrate Valentine’s Day with these wild couples:

Mate-Assistance Monogamy

One type of monogamy is called mate-assistance which occurs when males remain with a female to help guard and rear their young to secure healthier offspring.

Laysan Albatross

Not only does the laysan albatross fit this bill, but they also form this sacred pair bond for life.

Having scoured the ocean for food for the first few years of their life, albatross return to the same stretch of shore in which they were raised to find a mate. And they don’t take courting their partners lightly. Albatross will invest 8-9 years learning how to court and searching for that perfect partner.

Once chosen, an elaborate courtship display will take place. They perform a harmonious dance of clacking beaks and mimicry of motions. They will perform this same ritual with the same individual in the same location every breeding season for the rest of their 50 year plus life. The oldest known bird in the wild is a Laysan albatross which nests on Midway Island. This golden-ager, named Wisdom, is at least 65 years old.

Mate-Guarding Monogamy

Another type of monogamy is called Mate-guarding. This allows males to prevent rivals from copulating with their female and thus protects his offspring. This often happens in communities where it is difficult to locate a female, or where the sex ratios are uneven.

Cuttlefish

Courtship is not an easy game among the male cuttlefish. Males outnumber females 10 to 1 so the competition to pass on genes is fierce.

Males will intimidate each other with changing coloration and skin patterns. In fact, a documentary by NOVA entitled, “Cuttlefish: Kings of Camouflage” explained that cuttlefish have “electric skin” allowing them to change color instantaneously. Scientists believe they utilize this for camouflage, communication, courtship, and trickery.

When an electric performance does not prove male dominance, it’s time for full-body contact. The winner of the fight will guard his prized female for mating rights.

However, not all battles are even. Smaller males that have no chance in combat use a more unconventional approach. They mimic the appearance of females. While the large males are engaged in sexual warfare, the smaller males have successfully mated with the females’ right under their noses. Such males are never attacked by the larger mate-guarding males.

Female-Enforced Monogamy

Burying Beetle

Collectively the couple burying beetles bury and lay their eggs on a dead carcass. Once the eggs are laid, the male will release sex pheromones into the air to attract additional mates. The female will assault her mate by pinching, biting, and sucker-punching him. But it’s not due to jealousy that the female burying beetle violates her mate. Instead, it’s to protect her offspring from competing for food and nutrition with other larvae were he to mate with another female.

Extreme Male Monogamy

Some species, although monogamous, don’t conform to what most of us would consider a desirable outcome for the male. Here are two examples of male monogamy and sexual conflict:

Deep Sea Angler

If the idea of becoming one mind, one body, one spirit sounds a little clingy to you, then you will be fascinated with mating system of the deep sea angler fish. Living in the vast depths of the ocean where sunlight does not penetrate finding a mate may be difficult.

As the male angler fish matures, its digestive system degenerates; making it impossible to feed on his own. In order to survive, he must attach himself to a female as a parasitic appendage.

He then releases an enzyme that fuses the tissues of his body to hers. The two become one, joined by the central nervous system. This parasitic male leaches nourishment from the female, but it is a good tradeoff because she will receive a constant supply of sperm for the spawning season.

Praying Mantis

Being eaten alive is just another day in the life of a Praying mantis. For this aggressive couple exhibits sexual cannibalism. During copulation, it isn’t unusual for the female to eat the head of her lover. It is not truly known why this feasting of the suitor exists, but there are a few theories of why.

According to an article in the Oxford Journal, one speculation is that this is an adaptive foraging strategy, providing the female with nutrients for survival and to enhance her breeding success. Another proposal is that it is a result of strong selection for female’s aggression in early life stages. Either way, I wouldn’t want to be on the opposite end of her jaws of love.

In environments where resources are unevenly distributed, competition for mates may become intense. Wildlife sometimes prefer a polygamist relationship with two or more lovers. No, it’s not because they’re party animals, it’s driven by supply and demand.

Check out some of the different types of polygamy and the wildlife that exhibit these behaviors:

(Also be forewarned, these species have evolved to be pretty scandalous.)

Polygyny

Polygyny is an adaptive type of polygamy where one male mates with several females in one breeding season.

Lyrebird

If you want to get the attention of a potential mate, then try doing what the lyrebird does and mimic chainsaws, camera shutters, and other birds. Lyrebirds, native to Australia, have a dispersed polygynous, “lek” mating system where males congregate in a cluster of small territories, collectively called a lek, and perform elaborate visual and vocal displays to persuade females to mate. Lyrebird males mate with any females that they can attract, and as many as they can in the same breeding season. They do not form pair-bonds and emancipate themselves from parental care.

During sexual displays, the male Lyrebird coordinates each song with an intricate dance to woo the ladies. His acoustic repertoire includes sounds from his environment: kookaburras, dingoes, car alarms, ringing phones, crying babies, rifle-shots, and even laser guns. He can also imitate over 20 different species of birds. When the breeding season hits-between June and August, it is not uncommon for the male to spend six hours a day performing his concerto. His sound is so perfect that he is often mistaken for the real thing.

Elephant Seal

The elephant seal takes a contrasting and more violent approach to polygyny called female-defense polygyny. This is where females form groups (called harems) and are controlled by a single alpha male. Elephant seal harems can contain up to 100 females.

These three-ton mammals have a reproductive strategy focused solely on inseminating as many females in their harem as possible while doing nothing to help rear their offspring. Males often battle each other for mating dominance. These aggressive battles are often blood baths and sometimes even end in death.

Polyandry

One of the rarest and most unusual domestic arrangements in the animal kingdom is called polyandry. In this mating system, one female mates with and controls the breeding activity of several males. Typically, but not always it involves sex-role reversal.

Dunnok

Although pair-bonding between the alpha male and female dunnock are secure, females will concurrently court a second male. This is a form of trickery to guarantee paternal care to her offspring.

When the dunnock’s alpha suitor is foraging, the female will sneak into the bush and copulate with the beta male. Once finished, she displays her rump for her alpha. He expels the sperm of the beta male by pecking at her genital opening and then mates with her himself. Dunnocks take just one-tenth of a second to fornicate and can mate more than 100 times a day.

Though polyandrous mating is the most common in the dunnock, it has also been observed exhibiting monogamous, polygynous, and polygynadrous mating systems.

See an amazing video of the female Dunnok courting two suitors from BBC.

Polygynandry

Polygynandry involves having an exclusive relationship with more than one partner. This is commonly associated with multi-male, multi-female group compositions.

Ring Tailed Lemur

Endemic to Madagascar, the ring-tailed lemur displays a third type of polygamy called polygynandry.

In these female-dominant colonies, the sense of smell (olfaction) plays a crucial role in group communication. In displays of aggression, males will engage in a social display called “stink fighting” where they rub their tales with scent glands located on their wrists, and then flick their tales at one another. These “stink fights” can last from 10 minutes to one hour. The males also waive this perfume at females in hopes of seducing a mate.

Promiscuity

Promiscuity is similar to a polygynadrous mating system except that there are no pair bonds formed among specific individuals.

Sea Hare

In the sea hare community, there is certainly no discrimination. Sea hares are a hermaphroditic species (containing both female and male sex organs). When it is time to mate, they release a pheromone called attractin that is 1000x more potent than human pheromones. They create copulation chains, alternating between genders. If the group reaches 15-20 sea hares, this performance will last for days. Check out this video of these mating chains:

Dressing Up

Consider the antlers of buck deer or bull elk or the mating plumage of male songbirds, ducks and peafowl. All of these points are important to attracting a mate, plus they can scare off competitors. Like a pricey power suit, bright plumage, antlers, bright spots on a bird’s bill or a lizard’s throat, say to potential mates, “Look at me and be awed. I’m strong and healthy enough to put energy into growing these doodads.  I’m powerful and skilled.”

More generally, species-specific colors and appendages—a robin’s red breast, or a male mountain gorilla’s silver back—say, “Make no mistake about it, I’m a member of such and such gender, and I’m a dazzling example of our species, so what’s not to like?”

Individual members of many animal species learn from infancy that appearance is important. In fact, through a process called imprinting, individuals come to identify with the look of the creatures that raise them, which usually means their parents and ensures that they seek mates and companions from their own species. But you can take a newborn animal and mess with its head: Austrian zoologist Konrad Lorenz once raised a rook (a European member of the crow family) so that it became imprinted on him; as an adult the rook, interested in mating, tried to stuff worms into Lorenz’s ears as part of a (misdirected) courtship feeding ritual.

Bearing Gifts

Valentine’s Day is a prime gift-giving holiday, part merchandizing ploy and part courtship. But giving gifts to prospective or actual mates is not uniquely human.

Bonobo (a.k.a. pygmy chimpanzee) males sometimes offer fruit to females with which they want to mate. Many male spiders present dead insects to prospective mates, in part to keep the indiscriminately predatory females from eating the suitors. In some spider species, males wrap an insect gift in silk webbing so the female will be preoccupied with unwrapping it, further enhancing the males’ odds of escaping the mating process alive. (The males of at least one spider species give females just a wad of empty silk—ladies beware).

Some male birds are champion gift givers, offering complete nests to females. The bowerbird of Australia and New Guinea is a famed example, the male building elaborate nests decorated with small, often shiny objects that attract female attention. As with gaudy plumage, the nest tells females, “Hey, I’m a male in excellent physical condition, otherwise I wouldn’t be able to gather all these bits of bone, shell, fruit et cetera so I can offer you this delightful house with a rain-forest view.”

Among red-winged blackbirds, the males that lay claim to the best nesting sites get females first. In European storks, the legendary bearers of babies, the nest is a really potent gift. The birds mate for life, but their fidelity is to the nest, not the mate. Male and female return yearly to the same nest—not to each other—which has the effect of making them mates for life.

May I Have This Dance?

An obvious case is the peacock, with its outspread tail, which it will shake and rattle to attract females. Wild turkeys engage in the same ritual, with tom (male) turkeys spreading their brown tails like Puritan versions of peacocks. The expansion of body feathers as well as tail feathers makes males look larger and more fit, a display designed not only to attract females but to warn away other males.

Among the bird world’s real hoofers are the sage grouse and prairie chickens that gather on special dancing areas—flat, open grounds called leks—where they hop and stomp in a ritualized “dance” that attracts females. (Given that birds apparently descended from two-legged dinosaurs, one can only wonder if perhaps, millions of years ago, courting T. rexes capered about in thunderous, earth-shaking mating dances; probably not, but what an image!) In a real case of sharing, some American Indian peoples incorporated movements from prairie chicken mating dances into their own tribal steps.

Birds use other displays as well, such as eagles engaging in intricate mating flights, or male woodcocks spiraling into springtime skies as they issue mating calls. All show that the individual participants are fit, strong, agile—in all, a good potential mate.

Valentine’s Day: Wild about Red

Red, say biologists studying the color, is the shade of dominance and warning among nonhuman animals, too. In one study, rhesus macaques avoided people wearing red tee shirts and caps, but approached people in green or blue. Biologists have learned that red coloration on the faces and rumps of male mandrills—large African monkeys—gives them an advantage in attracting mates. Moreover, red plastic rings attached to the legs of male zebra finches increase their dominance.

So on Valentine’s Day, stick with tradition and go for the red.

Ernest Thompson Seton aside, there is a human behavior other animals are not known to share: the celebration of holidays. Happy Valentine’s Day! And may your courtship rituals prove true to your dreams.
