Extinct Birds

Haven't had much time recently to note recent news, so I'm playing catch-up here.

First, a new biological modeling system is being tested to determine whether it is economically feasible to try and save a species after it hasn't been seen in a while. Recent test subjects include the ivorybill and the dodo. (News source.)

California condors have made a nest in Pinnacles National Monument for the first time in 100 years. (News source.)

Lord Howe Island Stick Insect Recovery

A paper on this rediscovered insect:

The recovery programme for the Lord Howe Island Phasmid (Dryococelus australis) following its rediscovery
Nicholas Carlile, David Priddel and Patrick Honan (2009)
Ecological Management and Restoration 10(s1): s124-s128

Abstract:

"Until its rediscovery on Balls Pyramid in February 2001, the Lord Howe Island Phasmid or Stick Insect (Dryococelus australis) was thought to be extinct. It disappeared from Lord Howe Island soon after the accidental introduction of the Ship Rat (Rattus rattus) in 1918. In this paper, we report on the recovery actions undertaken for this critically endangered species since its rediscovery. Monitoring of the small surviving population on Balls Pyramid has shown it to fluctuate between about 9 and 35 adult individuals. As a safeguard against extinction, two adult pairs were removed from Balls Pyramid in February 2003 to establish captive populations in Melbourne and Sydney. Although all four founders bred readily in captivity, one pair died only a month after capture. The second female would have also died soon after capture had it not been for veterinary intervention using novel untested techniques. The single surviving pair bred successfully but the hatch rate of eggs was poor. For the next generation, both fecundity and hatch rates were low. The lack of knowledge regarding the specific husbandry requirements of this particular species undoubtedly contributed to these problems. Careful management, together with a cautious scientific approach, eventually led to all problems being resolved. Presently, there are more than 700 individuals and 14 000 eggs in captivity. Approximately 80% of incubated eggs are expected to hatch. To establish additional captive colonies, adults and eggs have been sent to other institutions, both within Australia and overseas. Now that the species is reasonably secure in captivity, the opportunity exists to reintroduce this iconic insect back onto Lord Howe Island, but this can occur only after the introduced rodents have been removed. A programme to eradicate both the Ship Rat and the House Mouse (Mus musculus) from Lord Howe Island is currently being developed."

More Monkeys Than Expected

WCS surveys found new large populations of two rare Cambodian primates: (Eurekalert)

"A WCS report reveals surprisingly large populations of two globally threatened primates in a protected area in Cambodia.
"The report counted 42,000 black-shanked douc langurs along with 2,500 yellow-cheeked crested gibbons in Cambodia's Seima Biodiversity Conservation Area, an estimate that represents the largest known populations for both species in the world.
"WCS scientists conducted the surveys with the Royal Government of Cambodia's Ministry of Agriculture, Forestry and Fisheries across an area of 300 square miles (789 square kilometers) within a wider landscape of 1,150 square miles (3,000 square kilometers), which is about the size of Yosemite National Park. The scientists believe total populations within the wider landscape may be considerably greater."...
"The two primate species are found in much lower numbers at other sites in Cambodia and in Vietnam. Prior to the recent discovery in the Seima Biodiversity Conservation Area, the largest known populations were believed to be in adjacent Vietnam, where black-shanked douc langurs and yellow-cheeked crested gibbons hover at 600 and 200 respectively. The total population of the two species remains unknown."

Greater Bamboo Lemurs

A new population of the rare greater bamboo lemur has been discovered in Madagascar. (Eurekalert.)

"Researchers in Madagascar have confirmed the existence of a population of greater bamboo lemurs more than 400 kilometers (240 miles) from the only other place where the Critically Endangered species is known to live, raising hopes for its survival.
"The discovery of the distinctive lemurs with jaws powerful enough to crack giant bamboo, their favorite food, occurred in 2007 in the Torotorofotsy wetlands of east central Madagascar, which is designated a Ramsar site of international importance under the 1971 Convention on Wetlands." ...
"For years, scientists believed but were unable to prove that greater bamboo lemurs (Prolemur simus) lived in the Torotorofotsy area. A collaborative effort between the Malagasy non-government organization MITSINJO and the Henry Doorly Zoo in the United States supported by the Margot Marsh Biodiversity Foundation and Conservation International (CI) resulted in researchers finding and immobilizing several to attach radio collars for further monitoring.
"The researchers believe there are 30-40 greater bamboo lemurs in the Torotorofotsy wetland, which is far to the north of the isolated pockets of bamboo forest where the rest of the known populations of the species live. Habitat destruction from slash-and-burn agriculture and illegal logging threatens the previously known populations that total about 100 individuals, making the existence of the newly found lemurs in a distinct region especially valuable."

White-Rumped Vultures Found in Nepal

The Himalayan Times is saying that a group of about 40 white-rumped vultures has been discovered in Beli Patela forest at Dhangadhi of Kailali district, Nepal. It also mistakenly says the vulture was previously considered extinct worldwide, but that appears to be incorrect. As BirdLife notes, the species has suffered catastrophic decline in Pakistan and India, but is still known to exist in some flocks there. And, there are populations elsewhere, though it is considered critically endangered.

Tigers in China

The Indo-Chinese tiger (one of several subspecies in China) has been captured on infrared film in a nature preserve in Yunnan Province. (News source.)

"Until now, no definitive evidence had surfaced for nearly ten years to prove that the tiger still existed in the wild in southwestern China, although field researchers had recorded footprints and other clues indicating the large cat’s presence in the region." ...
"China’s wild tiger situation is still very precarious. Currently, four subspecies in the country—the Northeast China tiger, the South China tiger, the Indo-Chinese tiger, and the Bengal tiger—have wild populations below 50 individuals. While the protection of their natural habitat is key to the survival of these animals, time is pressing and the danger of extinction remains a strong possibility. It is critical that we seize this moment to continue anti-poaching, conserve habitats, and increase investment so that China can protect its wild tiger populations from complete extinction."

Borneo Shark Found

One of the rarest sharks on Earth has been found again.

The Borneo shark, Carcharhinus borneensis, is listed on the IUCN Red List of threatened species, and is known from only 5 specimens since 1858. The last being in 1937.

A team of researchers from the University Malaysia Sabah identified the shark, along with a new crab and ray fish, during a survey of the Sabah and Sarawak area.

This shark is known to reach around 2 meters in length, give birth to live pups, and lives inshore. Its ecology and behaviors are virtually unknown due to its rarity, and it is known only from Borneo and a specimen near China.

Cambodian Vulture Conservation

From the Wildlife Conservation Society:

"Working in the remote forests of Cambodia, conservationists from the Wildlife Conservation Society (WCS) have just discovered Southeast Asia's only known breeding colony of slender-billed vultures, one of the world's most threatened bird species.
"Found in heavily forested country just east of the Mekong River in Cambodia's Stung Treng Province, the colony also represents one of the only known slender-billed vulture nesting areas in the world, and therefore one of the last chances for recovery for the species, now listed as 'Critically Endangered' by the World Conservation Union (IUCN).
"'We discovered the nests on top of a hill where two other vulture species were also found, one of which—the white-rumped vulture—is also 'Critically Endangered',' said Song Chansocheat, manager of the Cambodia Vulture Conservation Project, a government project supported by WCS, BirdLife International, World Wildlife Fund, the Disney Wildlife Conservation Fund, and the Royal Society for the Protection of Birds. 'Amazingly, there were also a host of other globally threatened species of birds and primates. It's a very special place.'
"Chansocheat's team immediately set-up 24-hour protection measures against poaching and egg collecting, and are now working with local communities to ensure that they are involved in—and support—longer-term conservation measures. 'We already have a successful WCS model working in the Northern Plains where local people benefit from conservation activities. I think we have a good chance of making it work here if we can find the support.'
"The slender-billed vulture is one of several vulture species in Asia that have been driven to the brink of extinction across its entire range due to Diclofenac, an anti-inflammatory drug used for cattle that is highly toxic to vultures. Diclofenac has lead to global population declines as high as 99 percent in slender-billed and other vulture species. Diclofenac is now being slowly phased out in South Asia, but not at a pace that assures the recovery of the vultures. Because Diclofenac is almost entirely absent from use in Cambodia, the country remains one of the main hopes for the survival of the species. However, these birds are still endangered from other threats, such as a lack of food due to the over-hunting of large-bodied mammals, loss of habitat, and sometimes direct hunting.
"The Cambodia Vulture Conservation Project has already been successful in helping stem the decline in Asia's vultures in Cambodia through a combination of scientific research, direct protection, food supplementation and awareness-raising. Satellite-collaring of animals has lead to a greater understanding of which areas are important to the two most threatened species, while simultaneous vulture 'restaurants' across the country provide both an additional food source for the birds and a chance to undertake coordinated counts to monitor the size and structure of the population.
"Chansocheat remains optimistic, adding 'We have the backing of local people and of the Government. If we can find financial support to extend what we know is already a successful strategy, then we should be able to conserve these species forever.'

Ivory Bill in the Mix


Just last December there were reports of more Ivory Bill Woodpecker sightings in Arkansas, where the bird was declared 'rediscovered" not so long ago. Reported sightings in Florida, and the story goes on


This has led to legal issues between conservationists / researchers and the Army Corps of Engineers.


The Corps of Engineers has been working on a $230 million irrigation project near the Big Woods area along the White River in Arkansas, but an injunction was placed back in July 2006 that blocked on site work. The pumps and motors have been continuing to be built and the Corps of Engineers is going to store them until such a time as they can be used.


With this injunction, and more sightings, one wonders about the affect rediscovering or even finding for the first time a mystery creature can have on the local economy, ecosystem and governmental systems.


For those who have not seen the identification chart for the Ivory Bill, follow the link (a snapshot is here for you as well). There is also an interesting publication by the US Fish & Wildlife that may be of interest. Of course the classic AUK outline of the Cuban Ivory Billed Woodpecker is also a good reference point for a historical basis.

Tamaraw Flourishing

From the news:

"Manila, Philippines (AHN) - Conservationists have successfully worked on stopping the declining population of the unique dwarf water buffalo. Previously, the animal was considered an endangered species due to hunting and deforestation.
"The tamaraw, or Bubalus mindorensis had been threatened by big-game hunters, deforestation by settlers, loggers and ranchers that placed it on the world's endangered list by 1970.
"The government has taken steps to conserve the species through a captive breeding program and the development of a 25,000-hectare jungle reserve, in addition to increasing the residents' environmental awareness.
"The latest official population count of the animal is 263, 'although the figure could even exceed 300 if reported loose sightings in the northern side of the Iglit Baco National Park are taken in,' reports the Philippine government.
"'The tamaraws have definitely survived. In fact, with the continuous efforts of the government, concerned sectors and the Mindorenos [Mindoro residents], they may even begin to thrive,' it added.
"First discovered in 1888, the tamaraw is three feet tall and has a weight of 300 kilograms."
