Vulture Awareness Day: Vultures I Would Like to See

Today is International Vulture Awareness Day, designated to build support for vulture conservation through a better understanding of their ecological role. To that end, bloggers are asked to contribute blog posts on vultures for a one-day blog carnival. (There is still time to contribute something if you have not done so yet.) Why is such a day necessary? Even though some vulture populations are thriving (such as Turkey Vulture), many are not. Old World Vultures have been hit particularly hard in recent years, with several species close to extinction. Some New World Vultures, too, are extremely vulnerable. As BirdLife puts it:
This comes against a backdrop of recent reports of problems facing vultures in Africa and the ongoing ones in Asia. Across the Indian subcontinent, populations of three formerly very common species of vulture have declined by more than 97% as a result of consuming cattle carcasses contaminated with the veterinary drug diclofenac.

There have been mass vulture deaths in East Africa associated with misuse of chemicals, huge population declines in West Africa due to habitat loss, and the disappearance of vultures from large areas of their formers ranges in South Africa because of the continued use of vulture parts in traditional medicine and sorcery.
Rather than dwell on such unpleasant topics (ably covered elsewhere), I would prefer to devote my blogging contribution to a subject dear to every birder's heart: what vultures I would most like to see in the wild.

Depending on whose list you cite, there are somewhere between 9,000 and 11,000 bird species in the world. Many are quite beautiful, many are rare, and many display interesting behaviors. So why would anyone be interested in seeing more vultures? Despite their disgusting habits, vultures have much to offer the birdwatcher. While ungainly on the ground, vultures are among the most graceful of flyers. Their large wings catch even the faintest of updrafts, so that the birds soar seemingly effortlessly. Turkey Vultures, and perhaps some other vulture species, possess a sense of smell, an ability present in few other birds. Finally, there is simply something charismatic about large animals, whether they are mammals or birds or members of some other class. So here is my list.

1. Andean Condor (Vultur gryphus)


I have long been fascinated with Andean Condors, going back well before I became a birder. These birds, among the largest birds in the world, are most at home in the high peaks of the Andes and breed 2-3 miles above sea level. Like the California Condors of North America, Andean Condors have declined over the past half century, though their situation has never been as dire. Also like California Condors, they have benefited from an active conservation program, involving the release of captive-bred vultures and the provision of fresh carcasses where necessary.

2. King Vulture (Sarcoramphus papa)

While most vultures tend to appear somber or at most muted, King Vultures adorn themselves with a dazzling array of colors. Their bare heads are a mix of bright red, yellow, and orange, and their black flight and tail feathers contrast sharply with their otherwise white bodies. These vultures are found in the lowlands of Central and South America.

3. California Condor (Gymnogyps californianus)

As the only condor native to North America, the California Condor clearly belongs on this list. Nearly extinct a few decades ago, the condor population has rebounded and now numbers in the hundreds. It is sometimes ranked among the success stories of the Endangered Species Act. The sad part is, even the free-flying population can barely be considered wild, dependent as it is upon a captive breeding program, provision of fresh carcasses, and regular interventions from medical staff when injuries or lead poisoning occur. I hope within my lifetime to see a self-sustaining population of condors in the West.

4. Lammergeier (Gypaetus barbatus)



Also known as the Bearded Vulture, the Lammergeier dwells in the high mountain ranges of Eurasia and Africa. Rather than compete with its larger relatives for fresh carcasses, the Lammergeier has specialized in breaking the leftover bones to consume the marrow. It drops bones (and sometimes turtles) onto rocks from the air to break them apart more easily. As much as 90% of its diet consists of bone marrow. This species is threatened in Europe but stable elsewhere.

5. Cinereous Vulture (Aegypius monachus)

The Cinereous Vulture, widespread in southern Europe and Asia, may be the largest of the Old World Vultures. Like other Old World Vultures, the Cinereous Vulture has a far more powerful beak than any of the New World Vultures. This allows it to tear open fresh carcasses. At times, the Cinereous Vulture has also been called Eurasian Black Vulture or Monk Vulture. Unfortunately, the species has declined due to accidental poisoning and scarcity of carcasses.

Animal Rights Activists Freeing Caged Ortolans

Hunting and eating Ortolan Buntings has been illegal in France since 1999, but the bird is considered a delicacy. Thus the practice of trapping and selling caged Ortolans to high-end restaurants continues. The songbirds killed for gourmet dinners may number in the tens of thousands. Recently animal rights activists have released caged Ortolans back into the wild.

In a co-ordinated protest, members of the League for the Protection of Birds (LPO) destroyed hundreds of traps and set free the birds inside. The time had come, they said, to prioritise biodiversity over gastronomy.

"For 10 years now, not only has the state turned a blind eye [to the poachers] but it has been complicit," said Allain Bougrain-Dubourg, president of the LPO. "It is time to make the state face up to its responsibilities."
Even when I am sympathetic with their goals, as in this case, I always hesitate when I read of activists released birds (or other animals) into the wild because in so many cases animals have been released into inappropriate habitat or domesticated animals have been released even though they might not be able to survive on their own. In this case, the birds are clearly wild in origin and the releases appear to be in their original habitat. At least I hope my reading is the correct one.

This seems like an issue dear to Charlie's heart, so I imagine he will have something to say about it.

EPA Planning to Declare CO2 a Pollutant, But Not Yet

According to news reports, Lisa Jackson is planning to declare that carbon dioxide is a pollutant.

EPA Administrator Lisa Jackson told reporters that a formal "endangerment finding," which would trigger federal regulations on greenhouse gas emissions, probably would "happen in the next months."

Jackson announced her timeline even as top senators said they were delaying plans to introduce legislation that would set new limits on carbon dioxide emissions. Senators had been scheduled to unveil legislation next Tuesday, but the date has now been pushed back to later in September.
Such a declaration would have serious effects.
The EPA can formalize the finding anytime, now that it has closed a 60-day public comment period that netted more than 300,000 responses.

A formal endangerment finding would obligate the agency to regulate greenhouse gas pollution under the Clean Air Act - even if Congress doesn't pass a final climate-change bill.

President Obama and Jackson have said they would prefer that Congress - rather than the EPA - take the lead in implementing new greenhouse gas limits. Businesses and energy industry leaders also have largely favored congressional action over EPA-imposed limits, because they believe lawmakers are better positioned to combine economic safeguards with any new carbon cap.
Carbon dioxide is not what we normally think of as pollution, since that term normally refers to toxic substances released into the environment. Instead, carbon dioxide is a normal product of our respiratory system, and it is vital for plants. However, the dose makes the poison, and in the case of carbon dioxide, excess amounts could trigger catastrophic climate change, which would be harmful to human health and well-being. So, as the Supreme Court recognized, it is right and necessary that the U.S. government take action on this issue. Given the current inability of Senate leadership to move useful legislation, regulations issued by the EPA may be the preferable route. If businesses would prefer that Congress deal with the issue, then they need to put some pressure on their favorite Senators to get a bill passed.
