Wake Up, World! We are About to Lose the Orange-Bellied Parrot!

The vibrant, critically endangered Orange-Bellied Parrot of Australia is only about 50 birds and three to five years away from extinction, but most have never heard of it.

Ever heard of the Orange-Bellied Parrot? Most haven’t. It’s one of the rarest birds in the world and can only be found in the great Down Under. One of only three parrots on our planet known to migrate annually, these boldly colored beauties may soon be known only from text books, much like the dodo bird. Despite rigorous conservation efforts, their numbers continue to plummet and now, even the captive population is threatened. Will the Orange-Bellied Parrot join Oceania’s Christmas Island Pipistrelle, Tasmanian Tiger, Pig-Footed Bandicoot, Laughing Owl, and Southern Gastric Brooding Frog on the list of little known species that are now gone forever?

A Unique Bird Adapted to a Very Specific Lifestyle
These small ‘grass parrots’ only grow to about 45-50 grams (about a tenth of a pound) and around 21 centimeters (just over eight inches) in length. Truly, the only “big” thing about Orange-Bellied Parrots is their coloring. They are splashed with vibrant shades of green, yellow, blue, and of course, orange. Their plumage closely resembles that of other native Australian parrots—particularly blue-winged parrots, which are often mistaken as orange-bellieds.

This species is endemic to southeastern Australia, where, unlike most parrots, they migrate between the mainland and Tasmania every year. It’s a fascinating journey, made with the intention of getting laid—eggs, that is. While their southward migration to Tasmanian breeding grounds is direct and quick, their return to the mainland is broken up, with stopovers at King Island and surrounding areas. Despite these behavioral differences, the birds always follow the same route to and from each location.

Orange-bellied parrots forage on the ground amongst short vegetation, feeding almost exclusively on the seeds and fruits of sedges, as well as those of salt-tolerant, aquatic plants and grasses. The abundance of their main food sources is largely reliant on specific fire regimes, with optimal conditions found in areas that have not burned for three to fifteen years.

Their specialized diet restricts them to select habitats where such forage can be found. Where the birds overwinter on mainland Australia, these include saltmarshes, sand dunes, beaches, pastures, and shrublands—always within a few clicks from the shoreline. At their breeding grounds in Tasmania, they are found in mixed forests near highland plains, where they nest in tree hollows.

Beauty and the Beast
The one thing that nearly all threatened, endangered, and recently extinct species have in common is humans. The impacts of sprawling human civilization have claimed habitat, introduced exotic species, and changed whole landscapes, sending many native, endemic organisms into a tail spin all over the world. The same holds true for the now critically endangered Orange-Bellied Parrot.

These birds was once hunted for sport and, for a period of time leading up to the 1960s, were also plucked from the wild for the exotic bird trade. Yet, a bigger threat has persisted. An explosion of agricultural, industrial, and residential development that began in the 1920s has taken over much of their restricted habitat throughout their range. What’s been left has largely been degraded by these and other human activities.

Although most noticeable in saltmarsh ecosystems, the loss, degradation, and fragmentation of their habitat has occurred throughout their range. In fact, their breeding grounds in Tasmania have been reduced to only a single location, in Melaleuca.
Additionally, the introduction of exotic plants and animals, concurrent with the movements of humans, has rapidly altered the structure and composition of the ecosystems used by the orange-bellied parrot. Invasive weeds–some being toxic to these animals, if ingested–now dominate much of their habitats, decreasing the abundance of and accessibility to native vegetation that the birds rely on for food.

They are also forced to compete with introduced animals for increasingly limited food sources and nesting sites, including creatures like European greenfinches and goldfinches, house sparrows, starlings, rabbits, hares, and house mice. The tiny parrots have also been preyed on by non-native predators, such as red foxes and domestic cats.
European starlings have been introduced all over the world and frequently outcompete native bird species for food and nesting sites, including orange-bellied parrots.

Here Today, Gone Tomorrow?
Though once considered locally abundant, orange bellied-parrots have undergone a steady decline for the last 90 years as a result of these factors. Researchers say the entire population has consistently been below 200 individuals since the early ‘80s. Only an estimated 50 persist in the wild, today.

Unfortunately, the less than favorable conditions of the bird’s little remaining habitat have had severe consequences for the population and appears to be impacting their ability to reproduce. The past two years have been particularly alarming for conservationists, as they’ve yielded the lowest breeding rates on record for this species.

Although the birds continue to migrate to Melaleuca, the number of successfully breeding females has taken a steep nosedive. This is thought to be a direct result of reduced habitat quality throughout their range and may, particularly, be driven by limited food availability and competition for nesting sites. Only twelve young are known to have fledged in each of the last two years. Tragically, this has caused further declines for the overall population.

At this point, every remaining individual and every addition to the population is critically important to the future of the orange-bellied parrot. Even just a few deaths will have significant repercussions for the species. Their numbers are now so few that any chance event—such as a natural disaster, an introduced disease, or any major and rapid climatic changes—could easily result in their immediate extinction.
Experts have concluded that, if current trends continue, we will witness the loss of this species within the next three to five years.

Bird Fanatics to the Rescue
Upon noticing the dramatic reduction in the bird’s numbers, researchers began monitoring the population in the late ‘70s and the Orange-Bellied Parrot Recovery Team was established in 1980. Four years later, an official Action Plan was introduced for the conservation of this species—the first of its kind in Australia!

Since then, the team has been working alongside Birds Australia and the South Australian Orange-Bellied Parrot Habitat Protection and Restoration Project for the future of these animals. With the help of dedicated volunteers, they’ve carried out regular surveys of the feathered beauties and have intensively managed their habitat, especially in Melaleuca. In recent years, these teams have been focusing on protecting and rehabilitating mainland parrot habitats, as well.

They’ve also provided extra food and nesting boxes at breeding grounds for many years. However, since observing the concerning downward trends in the parrots’ reproductive rates over the past two years, they’ve begun supplementary feeding year round, throughout the species’ range—in Tasmania, at migration stopovers, and on mainland Australia. They hope this will help to offset the factors challenging reproduction.

In 1985, a captive breeding program was set up with the goal of releasing birds to boost the numbers in the wild. Today, there are three facilities actively involved in these efforts. The breeding centers are located at the Adelaide Zoo, Victoria Zoo’s Healesville Sanctuary, and a third is in Hobart, Tasmania. The process has proven to be difficult, due to low fertility rates and chick survivability. However, hundreds of birds have been a released as a result of these programs.

Without the committed work of all of the people involved in the efforts to save the orange-bellied parrot, it’s almost certain the species would’ve been lost already. Many people have given their lives to these birds and have made tremendous personal sacrifices to do so.

Captive Populations Also Threatened
Most unfortunately, it now seems even the captive populations are under threat. Only six parrots were collected from the wild to begin the breeding programs over 25 years ago, which limited the genetic diversity of their descendants. As a result, these groups are now showing signs of inbreeding.

As you can imagine, releasing genetically-challenged birds will serve no benefit for wild populations and could certainly do more harm than good. In order to maintain long-term genetic viability, experts recommend using 25-30 individuals as founders for captive breeding programs. With the current circumstances surrounding the reproduction of wild orange-bellied parrots, appropriately obtaining individuals to add to the captive gene pool is quite a challenge.

In recognizing the urgency of increasing and improving the captive gene pool, efforts are already underway to collect birds from the wild. However, careful consideration is being given to how this is done, in order to avoid negatively impacting the delicate, wild population.

Are Orange-Bellied Parrots Doomed?
While some may say we should throw in the towel and call it a night, there is still hope for this species. Giving up on these beautiful birds would be ecologically irresponsible. Passionate people have been able to save species from the brink of extinction before.

Die-hard conservationists were able to thwart the extinction of the Mauritian Parakeet, when a maximum of only eight individuals remained just over 30 years ago. Thanks to their committed efforts, there are now over 500 of these birds and their numbers continue to grow. (Read more about the Mauritian Parakeet here.)

Indeed, the migratory nature of the imperiled Australian beauties and the factors synergistically working against them prove quite a challenge for their future. Yet all hope is not lost. The fat lady won’t sing until the very last Orange-Bellied Parrot has ceased to exist. So, we must press onward and do all that we can to keep her loud mouth shut!

How Can You Help?
  1. Live in Australia? Traveling to Australia? Volunteer! The Orange-Bellied Parrot organizations and projects need help all the help they can get. You may be able to assist with surveys, rehabilitate habitat, hang nest boxes, or any of the many other things these organizations need assistance with. It’s not always the easiest job, but it is definitely worth the effort! In the most recent survey, volunteers exhausted themselves trying to spot these birds and were able to see six—that’s over 10% of the whole population! Imagine having the opportunity to see one of these extraordinary parrots with your very own eyes. Surveys are a critical part of the conservation actions for these birdies.
    To learn more about volunteer opportunities, visit Birds Australia HERE.

  2. Encourage local schools to get involved! Schools that visit Victoria’s Healesville Sanctuary are eligible to participate in a plant propagation project that benefits these critically endangered birds. Kids will learn about these animals and will be given the tools needed to grow their native food plants. When the seedlings are ready, the Sanctuary will take them back and use them to help save the species! Don’t live anywhere near Victoria? No problem. Use the net to look up schools in the area, email them information about the plant propagation project, and encourage them to get involved. Propagation kits do cost a little bit of money to cover the expenses of the materials within them. Maybe you want to offer the money to a school to sponsor the project? Or maybe schools outside Australia (or outside Victoria) can do fundraisers to sponsor the project? Kids helping kids, and learning about endangered species at the same time!

Shark Funeral: Hundreds of Illegally Slain, Threatened Sharks Buried at Sea in Galapagos Islands

The bodies of 379 sharks of at least seven threatened species were returned to the water days ago, after being seized from a vessel illegally fishing in the Galapagos Marine Reserve.
The bodies of 379 sharks of at least seven threatened species were returned to the water days ago, after being seized from a vessel illegally fishing in the Galapagos Marine Reserve. 
Last week, marine ecologist, Dr. John Bruno, brought the world’s attention to the seizure of hundreds of dead sharks from a fishing vessel intercepted by Galapagos National Park (GNP) authorities and the Ecuadorian Navy. The ship had been illegally fishing inside the Galapagos Marine Reserve. It was the largest seizure in the park’s history and resulted in the arrests of 30 people on board. After a team of researchers assessed the illegal haul, the bodies were returned to the ocean, while three of the criminals were forced to watch. The incident highlights the unsustainable nature of illegal shark fishing operations, which are on the rise in the Galapagos after the collapse of local sea cucumber fisheries.

The purpose of the Bush Warriors organization is to create global awareness about the plight of the world’s wildlife and biodiversity. Many human activities are responsible for species declines around the globe. Exploding human demand for animals and their body parts is fueling some of the most horrific, inhumane, exploitative crimes against wildlife— poaching, bushmeat trade, exotic animal trade, and so much more. Some of the world’s most popular animals— elephants, rhinos, tigers, lions, dolphins, bears, and more— are on the brink of extinction because of this. At the current poaching rate these species are expected to permanently disappear from their natural habitat within the next 20-50 years. Some, such as central African elephants, could be gone in less than three years.

Global Alliance for Rhino Conservation (GARC)


“Every country and each citizen of our planet has to join hands together in a global alliance to protect life on earth. Biodiversity is our life.”
-UN Secretary-General Ban Ki-moon

Background

The Greater One-horned Rhinoceros is perhaps the most enduring emblem of Nepal's rich biological heritage. Rhinos are precious gift of nature not only for us but also for our future generation. Not only is it important to conservationists for its ecological value but it also holds a universal value. The Greater One-horned Rhinoceros (Rhinoceros unicornis) is classified by the IUCN Red List of Threatened Species as "endangered,”.

Out of five species of rhinoceros in the world, one-horned rhinoceros is found only in Nepal and India. In Nepal, Chitwan National Park (CNP) and its surroundings, Bardiya National Park (BNP) and Suklaphanta Wildlife Reserve (SWR) are the main habitats of the rhinoceros. Kajiranga National Park in India houses the largest number of one-horned rhinoceros. Chitwan National Park was established in 1973 with the objective of protecting one-horned rhinoceros and its habitat. Chitwan National Park was recognized as a World Heritage Site in 1984 for its high biodiversity and for maintaining ecological process ecosystems of international significance (DNPWC 2001).

In Nepal, the rhinoceros population was estimated at 1000 individuals until 1950 in the Chitwan National Park. In 2008, rhino population size is estimated at 403 individuals in three Terai protected areas of Nepal. So, the number of one horned Rhino is decreasing dramatically putting this species at high risk of extinction. In recent years, rhino poaching has been one of the major threats for the survival of this species (Rhinoceros unicornis) despite great efforts to curb wildlife poaching and trade in Nepal.

The main factor behind this is-the existing national policy is not strict enough or wildlife friendly, creating an easy environment for wildlife criminals to escape prosecution since they are getting protection from corrupt political bodies


In order to save the one horned rhino, Team for Nature and Wildlife (TNW), a youth's environmental organization, including the concerned local and national animal welfare organizations has been struggling to minimize the poaching of the Rhino. In this regard, TNW has launched a campaign titled "Mission Rhino- Direct and Grassroots lobbying". The campaign includes strong lobbying activities, led and run by youths at local and central level to influence the government to revise existing policies and practices and putting an end to the trend of providing political protection to Rhino poachers.


The government of Nepal has just shown commitment to the conservation of its rich biodiversity and the survival of flagship species like Greater One-horned Rhinoceros for over four decades. But the there has been no significant changes in the control of poaching; in fact the conditions have been worsening everyday leading the species towards the brink of extinction in Nepal. Therefore, the time has come for carrying out lobbying initiatives from the global level through the global animal rights movement. This would hopefully bring about the required action from all the stakeholders involved in this issue for a positive change.

In this regard, TNW Nepal, on the behalf of all the Nepalese organizations involved in environment conservation has decided to form "Global Alliance for Rhino Conservation (GARC)" to save the endangered Rhinoceros together. The alliance formed in the eve of AFA 2010 will be a milestone step towards achieving the goal of International Year of Biodiversity (2010) declared by the UN.

Serpents
Nothing frightens people more thoroughly than snakes. Fear is the single most important fact behind the indiscriminate killing of snakes. Snakes, whether poisonous or not, are generally killed on sight. The sighting of a snake generates a hysterical mob armed with all manner of sticks and stones. The snake is invariably killed because if it is not, people feel it will wreak its revenge for any undesirable attention given to it.
Snakes have occupied almost every niche in the earth’s ecosystem. There are snakes that live on trees (arboreal snakes), there are snakes that have made the ocean their home (sea snakes), there are snakes that live in fresh water (water snakes), there are snakes that live underground (fossorial snakes: these depend on homes made by other creatures. Very often, a snake will enter a rat’s burrow, eat up the inhabitants and make the burrow its home). Then, finally, there are snakes that occupy the ground (terrestrial snakes). So, as we can see, there snakes have specialized to take advantage of every available earthly habitat. All snakes are predators and since they have such a wide range of habitats and vary in size from a few inches to around 25‑30 feet, they also prey upon a wide variety of creatures ranging from insects, lizards, birds, fish, frogs and rodents to even pigs and deer. As predators, snakes play a vital role in controlling the population of these animals -- especially rodents, frogs and insects -- since a majority of the snakes feed on them.
In turn, many creatures also prey upon snakes: birds of prey, the mongoose, civet cats, peacocks etc regularly feed on snakes. In fact, rats and larger frogs and birds like the crow and mynah will not pass up an opportunity to eat a baby snake. So apparently the population of snakes in nature is kept in check by these animals and thus, a balance between the various populations is achieved and maintained.
 When human beings enter this scenario, everything changes. Human beings not only alter and destroy the habitat of snakes and other creatures, as far as snakes are concerned they will not hesitate to kill them simply because they fear them. Although most snakes found in India are harmless (non‑venomous), they are still killed because of the lack of information about them and due to an overabundance of myths and misconceptions about them. Then, of course, there is also the trade in snake skins. Therefore the population of snakes is being decimated at an unnaturally high rate.
On the one hand, snakes are being killed relentlessly by human beings and on the other, their main source of food, that is, rodents (rats and mice) continue to benefit from the farming activities of "humans", increasing their populations to alarming proportions. Rodents consume about 25% of the total food grain produced every year in India. Allowing such an unnaturally high population of rats and mice can also lead to the spread of dangerous diseases like the plague and other diseases transmitted by them.
 Snakes probably have the largest number of myths attached to them and are generally ill treated because of them.But there are other myths:
  • ·         Snakes hunt human beings: False. Snakes never hunt humans. They usually hunt small rodents, birds, etc. Given even the slightest warning, a snake will run away from humans. They only attack in self-defence, when surprised or cornered.
  • ·         Most snakes are harmful: False. Most snakes are harmless.
  • ·         Snakes feel slimy: False. A snake is cool and dry to the touch.
  • ·         Snakes can hypnotize people and animals: False. The myth probably rose because of the way snakes stare without moving, and because many animals freeze when a snake stares at them.
  • ·         Snakes are aggressive and strike whenever possible: False. Most snakes are cowards that prefer to swish away and avoid a fight.
  • ·         Snakes are revengeful creatures and seek out the person who has injured it or his family: False. All snakes are afraid of human beings and will keep away from people as far as possible. Moreover, snakes have a very tiny brain and cannot remember such incidents so as to be able to take revenge days or months later.
  • ·         some snakes have two heads. False. There is no such thing as a two headed snake. Snake charmers encourage people to believe in this myth when they display the Sand Boa snake which has a blunt tail which looks almost like its head. 
  • ·         Snakes cause leprosy. False.  This myth has probably arisen because some snakes have mottled skin. However no snake causes leprosy or any other illness in human beings. Snakes are clean animals.
  • ·         Cobras guard jewels and treasures. False. Snakes have no use for precious stones and money nor are they even attracted to them. This myth has probably arisen as a consequence of movies which create such fantasies, preying on peoples fears.
  • ·         Cobras have a diamond in their head. False. This is logically, simply impossible.  No snakes have any jewels embedded in their bodies. Neither do they have any supernatural powers which enable them to create precious stones or any other objects.
