Humans go to great lengths to help bring animals back from the brink of extinction: conserving enormous tracts of land, putting in place policies to protect them in the wild, and, of course, captive breeding programs. But it can take a lot of coaxing to get animals to reproduce in their manmade environs. Here’s a look at the strange and funny extremes keepers and conservationists have gone to to help three species procreate. Warning: we’re about to discuss various ways to collect semen and spur animals to get it on.
Kakapo parrots will mate with… anything?
Meet the kakapo, the most ridiculous bird you have never heard of. Weighing in at eight pounds, these hefty New Zealand parrots can’t fly. Instead, they waddle around the forest floor and climb trees with their sharp claws. Well camouflaged by their olive green feathers, kakapo’s defend themselves by freezing in place.
For all their charisma, kakapos are critically endangered. By 1995 their population had dropped to 55 birds due to human hunting and introduced predators like cats and dogs. Intensive have since raise that number to about today.
Helping the kakapos reproduce is no easy task, as the species has, , “the worst reproductive strategy in the animal kingdom.” Male kakapos attract the ladies by toddling up to hills and cliffs, digging a hole, and howling into it. Their low-frequency “booms” can carry for up to three miles, and it’s up to the females to come and find them. Lady kakapos aren’t interested unless they are well-fed, so they only mate when the rimu tree (their favorite food) produces a lot of fruit every few years. But heftier kakapo moms give birth to only male chicks, so too much food results in fewer females to carry on the species.
Frustrated male kakapos sometimes mate with inanimate objects, and one bird named had a particular lust for people’s heads. Scientists tried to take advantage of Sirocco’s predilection by designing special headgear that a keeper would wear to collect his sperm for a . Unfortunately, Sirocco didn’t take a shine to the , but he still enjoys carousing with helmet-free heads.
Lonesome George wasn’t always so lonely.

Lonesome George, the century-old tortoise who just passed away in , was unlucky in love. Found alone and sick on Pinta Island in 1972, this Galapagos giant tortoise was the last of his subspecies. For George, there were no more fish in the sea… or rather turtles on the island.
Conservationists desperately wanted George to pass on his genes, so they tried to set him up with females from related subspecies. But poor George didn’t quite know what to do, so his keepers taught him the language of love by manually him themselves.
After this intra-species sex-ed, George shared a pen with two females for 16 years. Although they did mate and lay eggs, unfortunately no little half-George tortoises were ever born
Pandas enjoy naughty television, too.

It’s hard to get in the mood in a zoo, far from home and with so many observers watching. But the reproductive success of captive animals, like giant pandas, is often crucial to keeping the species alive.
There are less than left in the wild, due to the destruction of their bamboo forest habitat, so zookeepers are anxious to breed captive pandas and increase the population. Pandas are notorious for their reluctance to romance in captivity, but keepers at Thailand's Chiang Mai Zoo had an ingenious idea to inspiring their two bears.
Pandas Chuang Chuang and Lin Hui were great friends, but nothing more. To put them in the mood, keepers showed the male videos of other pandas in the act. A of panda cubs were born 2010, but it is unclear whether “panda porn” helped boost reproductive success. Other zoos have tried slipping male pandas some , in the hopes that the libido-booster will work in bears, too. Unfortunately, the little blue pills didn’t do the trick.
