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.

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?

More for Your Money
Normally, here at Not Extinct Yet, I tend to focus on organizations that are working on conservation of endangered species or animal groups--the Kakapo, the Vaquita, Rhinos, Frogs, etc.
But for Earth Day 2008, I thought I'd present an opportunity to give, which will help conserve an endangered ecosystem--the Atlantic Forest of eastern Brazil. The forest, a hot-spot of biodiversity, has lost 93% of it's original area. It is home to many endangered species, including the Golden Lion Tamarin.
The Nature Conservancy, one of my favourite organizations, has started the Plant a Billion Trees campaign, to restore the Atlantic Forest. Their goal is to, well, plant a billion trees obviously. Over the next seven years, they will plant Guapuruvu, Golden Trumpet, Ice-cream Bean, and Capororoca trees, which will restore important habitat, as well as remove CO2 from the atmosphere.
For just $1, you can plant a tree. Every tree counts!
Happy Earth Day!

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.

Possibilities
I can't really point to a specific incident that caused me to feel strongly about endangered species. I do know that I've always enjoyed learning about interesting plants and animals (and they're all interesting, if you look hard enough). Probably, it's the thought that I may never get to hear the booming calls of the New Zealand kakapo, or see a black-footed ferret peeping out of an abandoned prairie dog mound in South Dakota, or swim in salty blue water with a leather back turtle. I may not get to do some of these things even if all endangered species survive years into the future, but I'd rather live in a world where the possibility exists.
