Numbat Numbers

Numbat (Myrmecobius fasciatus), Endangered

Having just spent several months living and working in Australia, Australian species are especially interesting to me right now. Koalas, Kookaburras, and Kangaroos all crossed my path, as did Wallabies, Wattles, and Wombats. What didn't cross my path was a small creature known as a Numbat. This is likely because the Numbat is no longer common in the state of Victoria, where I spent almost all of my time.

Numbats used to live all across the southern regions of Australia. Their population was reduced to two tiny pockets in the state of Western Australia after the introduction of foxes. Since then, it has been reintroduced to a few small conservation areas, but still numbers less than a 1 000 animals in the wild.

The Numbat diet is a little bit monotonous, consisting of nothing but termites. Each individual can eat between 10 000 and 20 000 termites in a day! Unlike many other termite eating animals, however, Numbats are small, and lack claws or any other method to open up termite nests. This means that they have to forage for termites when the termites themselves are out of the nest foraging--that is, during the day--making it one of the very few marsupials active during the day. Being active during the day like this is thought to make them more susceptible to predation.

In the evening, when they aren't foraging, these rare marsupials retire to their burrows, which are very often inside of hollowed out logs. It is thought that an abundance of hollow logs to hide in may have saved the two groups of Numbats that survived in Western Australia, as they provided protected hiding places from predators.

These stripy furry animals are cute, no doubt about it. They're one of Western Australia's State Emblem's, and they've also been chosen as the icon for the Conservation Council of Western Australia. A captive breeding and reintroduction program is underway, and Numbats are bred at Perth Zoo and released each year into managed habitat. Here's a great video about hand-rearing baby Numbats at the zoo.

Orange Bellied (Yellow Breasted Green Headed Blue Winged) Parrot

Orange Bellied Parrot (Neophema chrysogaster), Critically Endangered
Photo copyright Dave Watts
The Orange Bellied Parrot is sick, and this is a really bad time to be sick.

With a mere 50 or so individuals surviving in the wild, this species is edging closer to extinction every day. For the past few years, the wild population has been estimated between 140 and 180 birds--a steep decline from 'common, or locally abundant' in the 1920s. Only in the past year have the numbers dropped even lower as sightings of wild birds have grown fewer.

Three captive breeding populations exist in zoos around Australia, and it's these unfortunate Orange Bellies that are sick. An unknown virus has infected birds in the captive breeding program, causing some of them to lose their feathers and weakening their immune systems. Scientists believe that the virus may spread more easily in the captive population because they are so close to each other. The program has had some success annually releasing captive-bred birds to help sustain the wild population--so if the captive breeding program suffers, so will the wild population.

Orange Bellies are a migratory species, breeding and nesting in southwestern Tasmania, and spending the rest of the year in coastal areas in South Australia, Victoria, and New South Wales. This month is migration month, and all wild Orange Bellies are making their way south to Tasmania, where mated pairs will build nests and lay 2-6 eggs.


Of course, these parrots also face the usual threats of habitat loss and invasive species. You can learn more about their food, habitat, life cycle, and what's being done to help them here. If you live in Australia and want to help, you could volunteer with Birds Australia.

3000 Frogs Isn't Very Many

White-bellied Frog (Geocrinia Alba), Critically Endangered

Sixty White-bellied Frogs are now exploring their native habitat for the first time, after being released into the wild last week. These glossy bellied frogs live only in the province of Western Australia, where they have the dubious distinction of being this region's only critically endangered frog species.

The total population of all White-bellied Frogs is estimated at less than 3000. This might be an impressive number if you were talking about Facebook friends or gigabytes of data, but when you're talking about the entire population of a species, 3000 equals hanging by a thread.

They are mostly being affected by habitat loss, and a related problem, habitat fragmentation. As humans encroach on their living space, they also divide it. These frogs are known to exist in 56 subpopulations, with no movement between any of the groups.

This latest release is the first time young frogs (aka froglets) have been introduced to the wild from the captive breeding program run by the Department of Environment and Conservation. Transplantations of large numbers of eggs have occurred, but the results of this new approach will help scientists determine the best methods of helping boost the population of this unique amphibian.

'Alalawhat?

'Alala (Corvus hawaiiensis), Extinct in the Wild

The 'Alala, has been Extinct in the Wild since 2002. What is an 'Alala you ask? 'Alala is the Hawaiian name for a bird that others call the Hawaiian Crow.



The last few wild birds lived out their lives on the island of Hawaii, in the Kona Forest Unit of Hakalau Forest National Wildlife Refuge. Now, the 'Alala no longer exists, except for sixty some birds in two breeding centers, (one on Maui and one on the Big Island of Hawaii), and a single bird at the San Diego Zoo.

The birds declined because of a variety of factors, including habitat alteration by wild cattle, sheep, and pigs. These animals would clear the underbrush of the native plants that the 'Alala depended on for food. The lack of underbrush also made the Hawaiian Crow more susceptible to attacks from it's main predator, the 'Io, aka the Hawaiian Hawk. Logging and the conversion of forested land into agricultural land added to the problem.

Recovery efforts have been underway since at least the 1970s, but with little success. Between 1993 and 1999, 27 captive reared birds were released. Twenty-one of those died in the wild, and the remaining 6 were recaptured to preserve their genetic diversity for the captive breeding program. The captive breeding population has grown over the years, but very slowly.

Currently, a single 19-year old bird is being kept at the San Diego Zoo, where it is hoped that it will be possible to collect his sperm, so that his important genes will not be lost, since he will no longer breed.

In 2009, the US Fish and Wildlife Service published an update to its recovery plan for the 'Alala, including plans for continued captive breeding and eventual reintroduction into conserved and protected habitats. In order to carry out the recovery plan, an estimated $14 million will need to be found.

You can stay up to date on the latest news and information about the 'Alala at Crows.net.

Collector's Item

Gooty Sapphire (Poecilotheria metallica), Critically Endangered












The first thing I learned about this tree dwelling tarantula, was that it has to be seen to be believed. When I saw a picture, I understood why. The rare beauty of this spider's color may be its salvation or its doom.

Native to a tiny, tiny, tiny, patch of India, this entire species occupies less than 100 km squared--and that's a generous estimate. Sounds big, but look at this map, and you'll see just how tiny it is.

With it's habitat being degraded as humans cut trees for timber and firewood, it's up for debate whether the smugglers who have spirited some of these spiders out of the country will ultimately help the spiders or cause their demise.

Coveted among spider and insect collectors and hobbyists for their colour, these spiders are being bred in captivity by specialist pet shops. A young Sapphire Gooty spiderling can fetch more than US$150. Although they are fairly rare right now, as hobbyists continue to breed them, they may become more common.

I don't generally support taking wild animals out of their native habitat for use as pets, but perhaps this time it might save them, or at least ensure that some remain if they can no longer survive in the wild.

What do you think? Is this biopiracy or conservation in disguise?

Vultures in Vain

Oriental White-backed Vulture (Gyps bengalensis), Critically Endangered
Indian Vulture (Gyps indicus), Critically Endangered
Slender-billed Vulture (Gyps tenuirostris), Critically Endangered

In the 1980s, millions of somewhat ugly but still majestic vultures congregated around the carcasses of dead and decaying animals throughout India, Nepal, and Southeast Asia, disposing of them in less than an hour. Today, with their population a mere 0.01% of its former size, carcasses of livestock sit for days or weeks, rotting in the sun.

What happened to the other 99.9%? Poisoned.

Diclofenac is a drug that was commonly used to treat inflammation and arthritis in livestock. When animals receiving the drug died, vultures would come to feast. A few days later, their kidneys would fail and death would follow shortly. Diclofenac is, as far as anyone can tell, the sole culprit for the decline of these useful birds.

Diclofenac has been banned for veterinary use in India, Nepal, and Pakistan since 2006, but is still available for human use--and some farmers still use it for their livestock.

Now, another drug commonly used to treat livestock, ketoprofen, has been shown to have similar effects to diclofenac. Ketoprofen is not used as widely, but it's becoming more popular. Although it's not as toxic as diclofenac, studies and modeling have shown that even with very small numbers of poisoned carcasses, massive declines in vulture populations would occur.

Conservation organizations, including the Bombay Natural History Society, the Royal Society for the Protection of Birds, and Birdlife International, are advocating the use of meloxicam. Though this drug is more expensive, it is the only drug known to be safe for vultures. Other drugs exist, but their effect on vultures is unknown.

Captive breeding centers for Vultures have been established, as well as Vulture restaurants, where undrugged carcasses are left out for the birds. There have been some successes with captive breeding, but the birds will probably not be released until harmful drugs are no longer a threat.

Back to Canada!

Black-footed Ferret (Mustela Nigripes), Endangered

The Black-footed Ferret is being reintroduced to Canada! Thirty-four endangered ferrets were released into Saskatchewan's Grassland National Park on Friday. They were released near a colony of Black-tailed Prairie Dogs, their main prey, as well as their architects, since the Ferrets live in abandoned Prairie Dog burrows.

All of the Ferrets released had a few things in common. They all were born in captivity, and therefore had to spend some time in a special facility in Colorado, where they learned which predators to fear, and how to hunt and survive in the wild. They also all have a small electronic chip implanted under their skin, which will help conservationists keep track of and study them.

For each of the next few years, 30-40 Black-footed Ferrets will be released into the park, with the eventual aim of having wild populations across North America. Conservationists warn, however, that time is still a long ways off. Although Black-footed Ferrets have been reintroduced to 19 sites across North America, only three of these are self-sustaining. The rest require new captive-bred ferrets each year to maintain their populations.

The only ferret native to North America, it looks like a cross between a raccoon and a weasel, with distinctive dark markings across its face and feet. It disappeared from north of the 49th Parallel around 1937 and was thought to have gone extinct across its range throughout Mexico and the United States sometime in the 1970s. Then came 1981, and a tiny population of 18 Black-footed ferrets was discovered in Wyoming. They were trapped, and taken into captivity, effectively making the species extinct in the wild.

With those original 18 animals though, a successful captive breeding program was begun, and Black-footed Ferrets have been reintroduced to the prairies of the United States and Mexico since 1991. The current wild population stands at around 750, with 250 more still in captivity.

The reason for the Black-footed Ferrets decline in the 20th century was tied to its main source of food--Prairie Dogs. As farmers and ranchers cultivated the land, they tended to see the Prairie Dogs as pests and a hindrance to agriculture. This view led to widespread poisoning and trapping, and huge reductions in population size, which were exacerbated by outbreaks of sylvatic plague. They continue to be threatened by the extreme fragmentation of their primary habitat, which has been occupied by humans for food production and living space.

You can learn more at the Black-footed Ferret Recovery Program.

Or you can adopt one. As the adoption website notes: This is a sponsorship program. You will NOT receive a black-footed ferret.

See if there's a zoo near you that has Black-footed Ferrets on display.

Farewell, Tiny Friends

Christmas Island Pipistrelle (Pipistrellus murrayi), Critically Endangered

Sometimes, saying goodbye is hard. It's not hard to say goodbye to your friend, when you're leaving the coffee shop, because you know you'll see each other tomorrow. It's a different story though, when you're saying goodbye to your friend, because they're getting on a plane to Peru and you don't know if you'll ever see them again.

That's kind of how I feel right now about the Christmas Island Pipistrelle. This tiny bat, weighing about the same as three paperclips, has been saying farewell for the past 14 years. For more than a decade, the CI Pipistrelle has declined at least 10% percent every year. Now, in 2009, the total number of CI Pipistrelles likely stands at less than twenty.

Without a last minute miracle, this bat is headed straight for extinction. In fact, it may already be extinct. With the hope of starting a captive breeding program, eight scientists have spent an entire month in an unsuccessful last ditch effort to trap any surviving bats.

The reasons for the relatively rapid decline of this bat are unclear. Most scientists involved seem to believe that it's demise is linked to one of the numerous non-native species introduced to Christmas Island--the small Australian island which is the sole habitat of the CI Pipistrelle. Whether it was the Common Wolf Snake, the Black Rat, the Yellow Crazy Ant, or some other species that resulted in its decline, the point is now almost moot.

Although there is a small chance that scientists may succeed in trapping a few bats to start a breeding program, as long as the non-native species remain, the Christmas Island Pipistrelle will not be living happily on Christmas Island.

And so, to the CI Pipistrelle, I bid a very sad farewell. I hope this isn't goodbye forever.

Nine

Black Rhinoceros (Diceros bicornis), Critically Endangered

100000 - The number of Black Rhinos alive in 1960
65000 - The number of Black Rhinos alive in 1973
14000 - The number of Black Rhinos alive in 1980
2300 - The number of Black Rhinos alive in 1993
4240 - The number of Black Rhinos alive today
9 - The number of Black Rhinos alive in a secret location

Nine Black Rhinos have recently been airlifted to a secret location in an effort to increase the range and numbers of these critically endangered African mammals. The World Wildlife Fund (WWF), in partnership with Ezemvelo KZN Wildlife (EKZNW), selected individuals from different areas and parks to help establish the new population.

The final destination of the nine founders is being kept a secret because of illegal poaching--the main factor in the rhinos' steep decline since the 1960s. Rhino horn is used illegally in traditional Asian medicine, as well as being highly coveted for ornamental use.

In Yemen, rhino horns are used for the handles of curved daggers called jambiyas, which are given to young men as symbols of manhood and religious devotion. Not all jambiyas use rhino horn--only the most prized and expensive.

The use of Rhino horn in traditional Asian medicine, however, is by far the greater threat. Rhino horn is used to treat a variety of ailments, including fever, rheumatism, and gout. The horn is usually shaved or ground into a powder and dissolved in boiling water. As more and more Chinese people accumulate wealth and the ability to pay for expensive treatments, the market for poached Rhino horn will only grow.

Alien Feeding Frenzy

Giant Ditch Frog aka Mountain Chicken (Leptodactylus fallax), Critically Endangered

In my last post, I wrote about the Mountain Chicken, it's plight, and the work being done by conservationists to set-up a captive breeding programme. These scientists have captured on film a weird and wonderful scene of the breeding habits of this rare frog. It is definitely worth watching.

Female frogs dig a hole and fill it with foam, lay their eggs, and once they've hatched, deposit unfertilized eggs to feed the developing tadpoles. What wasn't known before was just how eager the tadpoles are to get at the eggs. Instead of waiting for the eggs to drop to the bottom of the nest, the younglings swarm their mothers body in a frenzied competition for food.

To stay up to date on the progress of the conservation team, follow along at the dodo blog.

Get Us Out of Here!

Giant Ditch Frog (Leptodactylus fallax), Critically Endangered

The Giant Ditch Frog, also known as the Mountain Chicken by locals due to its size and the taste of its flesh, is confined to two small islands in the Carribbean: Montserrat and Dominica. Although it used to inhabit several other nearby islands, it's total current range on the two islands is less than 50 km squared.

What caused it's decline? Environmental factors such as hurricanes and volcanoes may have played a part, as well as over-harvesting for food, with an estimated annual take of 8,000-36,000 (the government imposed a hunting ban on this former national dish, when populations started to decline).

Adding to the dilemma of this critically endangered amphibian is the world wide chytrid fungus crisis, a disease that is decimating frog populations around the globe. Although the island of Dominica has been infected since 2002, the island of Montserrat managed to remain disease free--until recently. In late 2008 or early 2009 the fungus made the jump to Montserrat and is currently decimating the Giant Ditch Frog population there, killing hundreds in just the past few weeks.

Fortunately, Durrell Wildlife Conservation Trust and the Zoological Society of London (ZSL) have stepped in to help save this rare animal. Going into an area of healthy frogs where the disease had not yet reached, conservationists have successfully removed 50 individuals and airlifted them to Europe for use in a captive breeding program. Twelve of the Frogs will go to the ZSL, 12 to Durrell Wildlife, and the remaining 26 will go to Parken Zoo in Stockholm. The frogs will be kept in special biosecure housings to prevent infection by the chytrid fungus.

The goal is to breed the frogs and reintroduce individuals to disease-free areas of Montserrat within two years. Although the frogs have been bred in captivity before, it is a difficult process, as they have huge appetites and have unusual breeding habits for frogs. After digging a hole in the ground and filling it with foam, the female deposits 15-50 tiny eggs. The eggs hatch and develop into tadpoles, all in this isolated foam nest. For food, the mother deposits unfertilized eggs every few days for the young to feed on.

Although the captive breeding program promises hope for the Giant Ditch Frog, more needs to be done. Durrell Wildlife is currently raising funds to build an additional bio-secure facility to house these endangered frogs. For as little as 10 pounds (15 USD, 18 CAD), you can support the care of a Giant Ditch Frog. Donate or shop online or call Natalie Ranise on 01534 860013 (UK).

Mushrooms for Breakfast, Mushrooms for Lunch, Mushrooms for . . .

Gilbert's Potoroo (Potorous gilbertii), Critically Endangered

Gilbert's Potoroo, named for the English naturalist John Gilbert, is perhaps the most endangered marsupial in Australia. Known as the Ngil-gyte by local aboriginals, it is a small marsupial rat-kangaroo, with soft fur, bulging eyes, and a tail almost as long as its 30cm body. If you know what bandicoots and wallabies look like, a potoroo is somewhere in the middle. Fewer than 50 wild individuals are restricted to two tiny areas on the southern coast of Western Australia.

These shy nocturnal creatures are an oddity in the mammal world, in that they are fungivores. That is, 90% of their diet consists of truffles, the fruiting body of underground fungi. The spores of over 40 types of truffle have been found in their dung! The rest of their diet consists of small insects and small fleshy fruit.

It was first discovered around 1840 in southwest Australia, when John Gilbert wrote that large numbers were procured by aboriginals for food in the space of a few hours. By 1870, it was believed extinct. It wasn't until more than 120 years later, in 1994 that Gilbert's Potoroo was discovered, still alive in Two Peoples Bay Nature Reserve. Since then, a captive breeding population has been established in the same area, and another wild population has been established on nearby Bald Island. Currently, plans are underway to establish a third wild population at Waychinicup National Park.

The establishment of these distinct populations is crucial to increasing Gilbert's Potoroo's chances of survival. Threatened by wildfire (they live in dense, highly flammable vegetation that has remained unburnt for 50 or more years), introduced predators (feral foxes and cats), and changes to their habitat, their tiny population is at constant risk of extinction by a single catastrophic event. That is, a single wildfire could wipe out the majority of the population.

Research continues to learn more about the needs of Gilbert's Potoroo, as well as to help conservationists increase the breeding success of the captive population.

If you live in Western Australia, you can volunteer with the Gilbert's Potoroo Action Group, dedicated to preventing the extinction of it's namesake.

Kakapo (Strigops habroptila), Critically Endangered

According to Radio New Zealand, this year could be a lucky one. With a population of less than 100, the critically endangered Kakapo has been slowly increasing due to dedicated conservation efforts. This breeding season, the Kakapo Recovery Programme is hoping for forty chicks.

Previously on this blog, the importance of rimu fruit to Kakapo breeding was discussed, and it appears that a bumper crop may be in the works. Additionally, there are more fertile adult females, than there have been in years. If these factors come together, the Kakapo population could increase by nearly 50 percent. With so many chicks, some would be raised by their parents, instead of hand-reared by humans, as they sometimes are when chicks are rare.

The breeding season has started less than a month ago, with the first mating of the season occurring on Christmas night. Chicks are expected in late February.

Some Birds May Smell Sexier

Kakapo (Strigops habroptila), Critically Endangered

The Kakapo, featured here several times, might benefit from a little cologne it appears. Scientists working with the Kakapo breeding program, noticed that a few of the males received significantly more attention than others, and they think it may have to do with the birds' body odor. To find out, they're sending feathers to Tom Goodwin, an animal olfactory chemist in Arkansas.

Because the Kakapo's population dropped to a gene-pool-reducing 91 individuals, genetic diversity is very important to their survival. If most of the females are only breeding with a few males, the gene-pool could remain dangerously small. If a synthetic perfume that makes less attractive males seem sexier can be developed, their genes would also get remixed into the overall population, increasing the diversity of the gene-pool.

If you want to help save the Kakapo, you can donate, become more informed, or get hands on and volunteer with the Kakapo Recovery Programme.

Booroolong Frog (Litoria booroolongensis), Critically Endangered

Over a year ago, I wrote of the Booroolong Frog, a critically endangered species, confined to less than 10 square kilometers, and decimated by drought and forest fires.

Now, the species will receive a boost of 500 captive bred frogs, who are primed to breed. The 9 month old frogs are the offspring of 6 adults and 20 tadpoles that were taken into captivity two years ago. According to scientists involved with raising them, the males will mate in a brief breeding frenzy and die.

The species has declined because of habitat degradation and the chytrid fungus, which has affected amphibian species around the globe.

More Monkeys Is Good News

Gray Snub-nosed Monkey (Rhinopithecus brelichi), Endangered

This endangered monkey is confined to a 400 square kilometer reserve in China. Up until 1978, their mountainous home was severely disturbed and damaged due to mining activities. Since then, the Fanjing Mountains Natural Reserve has been established, and their population has increased from an estimated 400 in 1979 to 850 today.

Since 1992 the Fanjingshan National Nature Reserve Administration Bureau has successfully bred seven captured individuals, producing a mere 16 offspring-an average of one per year.

No More Protein!

Kakapo (Strigops habroptila), Critically Endangered

The Kakapo is a large ground-dwelling parrot, found only on two small, isolate islands in New Zealand. The total number of birds has risen to 91 in the past year, but this number is still precariously low.

Part of the problem is that Kakapo only lay eggs every three to five years, when Rimu Trees produce an especially large harvest of fruit. When this happens, the Kakapo feast and breed. Scientists have been trying to increase the frequency with which these beautiful birds breed, by supplementing their diets with protein, known to be an important nutrient for other breeding species.

Now, the importance of protein for the Kakapo is being questioned. Professor David Raubenheimer has recently analyzed the nutrient content of the Rimu fruit, and found that it is low in protein and high in calcium. He thinks that calcium may be more important for breeding Kakapo, as it would be used in their eggshells and incorporated into their unusually large skeletons.

Scientists will continue to try and increase the breeding frequency of the Kakapo to boost the population, by using a new formulation of feed that more closely matches the content of the Rimu fruit. One question still remains, however. Is it just the nutrients that are limiting the Kakapo, or are they programmed to breed only when there is an abundance of Rimu fruit?

If you want to help save the Kakapo, you can donate or just become more informed.

A Friend for Kim Qui

Yangtze Giant Softshell Turtle (Rafetus swinhoei), Critically Endangered



Back in December, I wrote about the Yangtze Giant Soft-shelled Turtle. Then, there were only two known Rafetus swinhoei known to exist, both in captivity, in separate zoos in China. It turns out that they aren't, in fact, the last two in existence. There are at least two others. One, highly revered by the Vietnamese and figuring prominently in legends as Kim Qui, the Golden Turtle God, lives in Hoan Kiem Lake, in Hanoi.

The discovery of the fourth, and only other known surviving turtle of this species, was recently announced by the Cleveland Metroparks Zoo. Scientists backed by the zoo spent three years searching in Vietnam, up and down the Red River. They finally found success at a lake just west of Hanoi, where locals said they occasionally spotted the rare turtle. As there are so few of these rare turtles left, every individual offers a greater hope for recovery. With only four known, however, prospects of long-term survival aren't very positive.

Rafetus swinhoei can live to be up to 100 years old, and perhaps it's not too late. There is a plan in the works to breed the male and female turtles from the Chinese zoos. So far though, no one knows for sure whether that attempt will be successful. Keep your fingers crossed.

Incremental Increase

Iberian Lynx (Lynx Pardinus), Critically Endangered



Three Iberian Lynx kittens have recently been born in captivity, boosting the population of the worlds rarest cat.

Saliega, raised in captivity since birth, has produced her fourth litter in as many years. Three kittens were born, but only two survived, which is often the case in the wild. However, Brisa, Saliega's daughter, produced two kittens of her own within days of her mother. Of those two, one was still-born, and the other is being cared for by staff at the breeding center in Huelva, Spain.

Azahar and Frans, another pair of Iberian Lynx at a zoo in Jerez de la Frontera, Spain, are expected to have a litter in mid-April.

There are currently only about 150 Iberian Lynx living in the wild, and scientists have estimated that there is a 95% chance the they will be extinct within 32 years, without drastic measures. A captive breeding program is underway, and additional centers are being constructed, but the problems of habitat loss and fragmentation continue to plague the recovery of Europe's last large feline.

Support efforts to save the lynx through petitions, donations, and other methods.

Kakapo - 91 and counting

Kakapo (Strigops habroptila), Critically Endangered


The critically endangered Kakapo is now five newly hatched chicks further away from extinction. The five chicks were recently hatched on Codfish Island a southern New Zealand island. The new hatchlings bring the world's total Kakapo population to 91, and if two more existing eggs hatch live chicks, it will rise to 93.

Part of the reason for the slow rise in Kakapo numbers, is that they only breed every three to five years. The breeding years are linked to years in which certain trees produce high yields of fruit. Scientists think that they may have found a way to mimic the conditions of these high fruit yields, by using some of the chemicals in the fruits themselves, that may trigger the birds to breed. If so, they may be able to increase the number of Kakapo eggs laid each year. For a more detailed explanation, check out this article.

Here's a video of a newly hatched Kakapo.
