Bird News

Scientists monitoring at Mount Moreland – South Africa’s largest Barn Swallow Hirundo rustica roost – have captured their first overseas ringed bird from a festively snowy location. The young Barn Swallow had flown all the way from Finland – a total of 11,000 km! “This is an amazing Christmas gift”, said Hilary Vickers of the Lake Victoria Conservancy – sponsors of the Mount Moreland ringing programme.

“We were carefully fitting the swallows with rings so we can monitor their movements when we spotted a bird already carrying one”, said Mount Moreland bird-ringer Andrew Pickles. “A magnifying glass provided the words Helsinki – Finland!”

                            The Bronx Zoo-based Wildlife Conservation Society announced today that its efforts to protect a wildlife-rich coastal region in South America have paid off in the form of a new coastal marine park recently signed into law by the Government of Argentina.

Last month a team of American and Honduran researchers and conservationists travelled to western Honduras to search for Honduran Emerald Amazilia luciae, a Critically Endangered species of hummingbird, endemic to Honduras. The principal cause of its decline is habitat destruction, with approximately 90% of its original habitat lost, and the remaining habitat occurring in isolated patches of arid thorn-forest and scrub of the interior valleys of northern Honduras. Based on specimen data, the species was originally known to occur in four Honduran departments, Cortés and Santa Barbara in western Honduras, and Yoro and Olancho in north-eastern Honduras. Despite efforts to find the species in western Honduras, it had not been reported there since 1935. The team conducted searches in Santa Barbara and Cortés and found six sites inhabited by the Emerald, all in the department of Santa Barbara.

NASA’s Got a New Web Site

NASA’s JPL has a new web site which focuses on surface conditions on one specific planet: The Earth. i-4b8c56f740cd31b2fd7d07fc2900d4ce-NASA_new_web_site.jpgIt has a Sea Level Viewer which is basically a very fancy menu for a number of multi-media presentations, and a list of current or proposed missions. I am not overly impressed with this, but it may be a good resource for the kiddies.Much more interesting, and in fact, quite impressive, is the “Climate Time Machine” … Continue reading NASA’s Got a New Web Site

On Sale in Madagascar: Carboni-caefbbb646c3239a71e76136a9a92c2b-wood-PC-1.jpg

This time, the forest product for sale is 100 percent sustainable and guaranteed to return on the investment. The product is carbon dioxide, the greenhouse gas that healthy forests can store in vast reserves and prevent from being released into the atmosphere. Put simply, protecting an intact forest keeps its store of carbon from heating the planet.In a landmark agreement, the Wildlife Conservation Society (WCS) and the government of Madagascar announced the sale of more than nine million tons of carbon offsets to help safeguard this African nation’s wildlife-rich Makira Forest. Proceeds from sales will also contribute to the economic wellbeing of people living around Makira and help fight global climate change.The carbon offsets will be marketed and sold by the Madagascar government in private transactions with the aid of the Makira Carbon Company (MCC) established by WCS. MCC will work in collaboration with Madagascar’s Ministry of Environment, Water, Forests, and Tourism. Sales will target principals, brokers, dealers, and other intermediaries in the U.S. and abroad who wish to purchase high-quality emissions reductions delivering multiple benefits to both the environment and economy.

Saving the world’s most threatened birds…i-79bde2734ae87f061395d43a460ac2ea-2.jpg

What’s the best way to save a species? Should we target conservation at individual sites, or perhaps use a much broader approach – taking action at the landscape or seascape scale? For 99% of Globally Threatened Birds, safeguarding Important Bird Areas (IBAs) is a key part of the solution.Questions of scale for conservation programmes are the subject of a paper by scientists from BirdLife International and Conservation International published in the inaugural issue of Conservation Letters. The study identified the most appropriate spatial scale of conservation efforts for 4,239 species of birds, mammals, amphibians and reptiles on the IUCN Red List.Experts classified each species into one of four conservation strategies. The results were stark. “For 79% of threatened bird species, the highest priority conservation action in the immediate future is to provide effective safeguarding of individual IBAs or networks of IBAs” said Dr Stuart Butchart, BirdLife’s Global Research Coordinator and a co-author on the paper.

Teshekpuk Goes to the Birdsi-1cb59d2727ca097c1890bb6a47a25038-4.jpg

As global energy demand soars, the Bureau of Land Management (BLM) took an important step recently to protect the heart of western Alaska’s Arctic coastal plain from commercial exploration. The Wildlife Conservation Society (WCS) applauds the decision to grant permanent protection to the Teshekpuk region, a key nesting site for migratory birds and other wildlife in the Arctic.Teshekpuk Lake is part of National Petroleum Reserve-Alaska (NPR-A). Encompassing 23 million acres, it is considered the largest single piece of undisturbed public land in the United States.”This represents a significant conservation victory for Arctic wildlife and demonstrates that there is room for both protection of key areas and for responsible energy development in the Arctic coastal plain rich in natural resources,” said Dr. Steven E. Sanderson, WCS President and CEO.

Resident waders disappearing down-underi-d83c2dd2cab7876afe6981ebdace38d0-5.jpg

A recent study of Australia’s wetlands has revealed that 81% of resident wading birds have disappeared in just quarter of a century throughout the mostly inland habitats of eastern Australia. The paper, published in Biological Conservation, reported that agricultural extraction and inadequate water allocation may have caused the steep declines.Scientists from the University of New South Wales undertook aerial surveys of wetlands in eastern Australia between 1983 and 2006. During the monitoring period all resident wading birds declined.The steepest drop was observed in Banded Lapwing Vanellus tricolor whose population plummeted by 98%. Further significant falls were detected in Red-necked Avocet Recurvirostra novaehollandiae (-85%), Black-winged Stilt Himantopus himantopus (-80%), and Masked Lapwing Vanellus miles (-69%). Because resident birds don’t leave the country – unlike their migratory counter-parts – the researchers concluded that the declines were causes by changes within Australia.Wetlands in arid Australia do not hold water every year. With many bird species relying upon wetland habitats for their food, the frequency of flooding is crucially important for their survival. Deluges of flood water – the life blood for breeding shorebirds – have been tamed by dams, levee banks and agricultural extraction. The researchers reported that wetland area declined at 40% of the most important sites. Floods are becoming increasingly rare.

Champion for Wild Tanzaniai-4c1cdbc381c9b22a44436429dcbfa9c2-6.jpg

Dr. Tim Davenport of the Wildlife Conservation Society’s Africa program has been named the recipient of the prestigious 2008 Parker/Gentry Award for Conservation Biology by the Field Museum in Chicago.The Field Museum is recognizing Dr. Davenport for his “outstanding achievements in conserving the unique biota of the southern highlands of Tanzania and other endangered habitats of eastern Africa.” Davenport collaborated with Tanzanian biologists and local community members to protect threatened wildlife and plants in Mt. Rungwe and surrounding montane forests. His work has been instrumental in the establishment of Kitulo National Park in Tanzania. In 2005, Davenport and his colleagues discovered the Kipunji, the first new genus of monkey found in more than 80 years.

BirdLife welcomes FAO report on bioenergyi-6ff3bbe2a7f1ef919b2ef7402026a380-7.jpg

BirdLife International has welcomed the launch of a report that highlights the increasing international recognition that while growth in bioenergy offers new opportunities for sustainable development, it also carries significant environmental risks.The launch took place at the Food and Agriculture Organisation (FAO) conference on World Food Security: the Challenges of Climate Change and Bioenergy in Rome, Italy. Entitled Bioenergy, food security and sustainability, the report cautions that with the use of current technologies and set policies, the growth in liquid biofuels is contributing to negative impacts on the environment and food security and is leading to an increase in world food prices.While governments, the private sector and civil society can take important measures to promote sustainable production of bioenergy, many challenges are global in nature and cannot be tackled without a concerted international response. The report suggests that “an international approach is needed to address the full spectrum of bioenergy applications including, most urgently, liquid biofuels for transport”.

Amboseli Lions May Go Extinct

i-2fdeccc605f17c96115dee1aede60def-lion.jpgBy African standards, Kenya’s Amboseli itself is small, but it is part of two or more large scale systems that extend far beyond its boundaries. One is the Serengeti Ecosystem, which extends far to the south in Tanzania. The other is the Nilotic (mainly Maasai) Pastoralist cattle keeping culture. It is being reported that lions in Amboseli are in crisis because of conflict between these two systems.From a National Geographic Society press release: Continue reading Amboseli Lions May Go Extinct

Impacts of anthropogenic climate change many, varied

A new study led by NASA links anthropogenic climate change to a wide range of effects. The study involved scientists from about a dozen institutions and agencies, and looked at biological impacts arising from global temperature increase since the 1970s. The article is published in Nature. According to lead author Cynthia Rosenweig, “This is the first study to link global temperature data sets, climate model results, and observed changes in a broad range of physical and biological systems to show the link between humans, climate, and impact … Humans are influencing climate through increasing greenhouse gas emissions and the warming is causing impacts on physical and biological systems that are now attributable at the global scale and in North America, Europe, and Asia.From the abstract of the paper: Continue reading Impacts of anthropogenic climate change many, varied

Tricoloured Mega-colony Saved

i-2735457fae44c59c10c9485df2cc4f99-tricolored.jpg

Audubon California has announced that it has reached an agreement with a farmer to safeguard a single colony of about 80,000 Tricoloured Blackbirds Agelaius tricolor – nearly a third of the world’s population of this Endangered species.The estimated global population of Tricoloured Blackbirds is 250,000 to 300,000 birds, with at least 95% of these occurring in California. Tricoloured Blackbirds have declined dramatically in the past century as native wetland habitat has been lost and the species has consequently been classified as Endangered. Tricoloured Blackbirds form just a few large nesting colonies each year, and in most cases these occur in crop fields. This puts the colonies in grave danger when farmers cultivate the field before young birds are able to fly.”This is really a great victory for conservation, and an example of how conservation and agricultural interests can work together to find real solutions”, said Graham Chisholm, director of conservation for Audubon California. “The Tricoloured Blackbird is an important part of California’s natural beauty, and this agreement, combined with other conservation measures, will help to ensure that it has a healthy future.”

Enigmatic Sex Ratio in a Nearly Extinct Bird

Pterodroma magentae is the Magenta Petral (also known as the Chatham Island Taiko). There are between 8 and 15 breeding pairs in the New Zealand home range of this species. Indeed, this bird was thought extinct for quite some time before it was rediscovered in 1978.A recent study indicates something funny is going on with sex ratio and mating strategies in this bird, which may, although I’m not quite sure how, lead to improved conservation efforts. From a BirdLife press release: Continue reading Enigmatic Sex Ratio in a Nearly Extinct Bird

Good News for Great Apes

i-f75550c7a8306d6bb0f04c2e339f6cd2-cross_river_gorilla.jpg

The world’s rarest great ape has found a safe haven in the mountains of the west central African nation of Cameroon. With guidance from the Wildlife Conservation Society (WCS), Cameroon’s prime minister, Ephraim Inoni, has created the world’s first sanctuary exclusively for the Cross River gorilla.Kagwene Gorilla Sanctuary spans only 19.5 square kilometers but contains an important segment of the Cross River gorilla population. The species’ range consists of 11 scattered sites in Cameroon and Nigeria. Of the estimated 300 or fewer Cross River gorillas that remain, approximately 20 live in the new reserve.”The creation of this sanctuary is the fruit of many years of work in helping to protect the world’s rarest gorilla subspecies,” says Dr. Roger Fotso, director of WCS-Cameroon. Fotso and his colleagues worked in tandem with the Cameroon Ministry of Forestry and Wildlife in laying the groundwork for the sanctuary.

The rest of the details are here.I am not personally convinced that this is the rarest population of great apes. The most threatened are certainly the eastern lowland gorillas of the Congo, of which there may be only a handful left. If any.
