This last eye-watering feat is like squeezing a cantaloupe out of a hosepipe, and one in 10 first-time hyena mothers die in the process. So how does a virtually immobile, somnolent bag of fermenting leaves avoid getting itself eaten? King penguins nest and breed on subantarctic and antarctic islands. Dotty and Zee, two males at the Bremerhaven Zoo in Germany, recently celebrated their 10th anniversary together and have even adopted a chick together. Males arrive at the colony first and choose their spot to wait for prospective mates. The female spotted hyena is the only known mammal with no external vaginal opening. The greatest single cause for reproductive failure in some species is the mistiming between parents for nest relief during incubation. One particularly effective hustler was recorded swiping 62 stones within an hour. Some penguins are full-blown sexual psychopaths who engage in prostitution, pedophilia and even necrophilia. Scientists routinely monitor wildlife on the island, and look out for rare and unusual behaviour.

They have evolved to hook on and hang from trees as the animal incarnate of a hairy hammock. Mutual displays continue throughout the breeding season, often taking place at the nest when parents switch places for egg incubation and chick feeding. This display seems to strengthen the pair bond, coordinate nesting behavior, and advertise a nesting territory. George Murray Levick, who studied penguins in the Antarctic for twelve weeks in With no parental duties, these singletons are free to go on a pebble-hunting extravaganza and amass veritable stone castles. For example, gentoos generally hold their outstretched head and flippers still, while macaronis flap flippers and roll their heads from side to side.

When the females arrive, sometimes a few weeks later, they go right back to their mates from the previous year. The lurid details of this avian orgy were delivered with deadpan Edwardian horror by Dr. As a result, they have almost dispensed with the need for weight-bearing extensor muscles, like our triceps, which stiffen and protract the limbs. Or a playful one that turned sexual. The BBC further reported Hunter as saying that the female penguins probably didn't engage in prostitution only for stones.

When a female selects a different mate it is usually because her mate from the previous season fails to return to the nesting area. So male seals may see each other coercing penguins, then attempt it themselves. This is when I gather my poise and explain that sloths are not a defective remnant. Once a female chooses her mate, the pair will go through an important courtship ritual, in which the penguins bow, preen and call to each other. All four known sexual incidents followed a common pattern. This usually occurs when the female fails to return from a foraging trip before the male deserts the nest.

Courtship complete, the pair then mates. In the Eudyptula, Spheniscus, and Pygoscelis genera, the first-laid egg is generally larger than the second, and usually hatches first except in the chinstrap species. Research suggests that females can tell how fat a male is — and thus how long he will be able to babysit the eggs without needing to run off in search of food — based on his song. She returns several weeks later, usually just before the egg is ready to hatch, to relieve her mate so that he may feed.

The data reveal that chimps enter into communities of hunting and sharing meat with each other over long periods of time and females within the meat-sharing community tend to copulate with males of their own meat-sharing community.

  3. They are the southernmost breeding of any bird and gather in vast crowds at the start of each summer to nest along the edges of the Antarctic Peninsula. They do, however, have a reasonable excuse: Since they carry their eggs around on their feet, there is no nesting site and therefore no obvious rendezvous point to meet a mate at the start of each breeding season.
