Common KingfisherRinging at Alba Marshes (Bahrain)

17 October 2012

As mentioned in a previous post Nicole and I went to Alba Marsh at the weekend ringing without Brendan for the first time since he left to return home to Ireland. The first two birds we caught were two male Kingfishers (dark lower mandibles) which must have been chasing each other and ended up in the net.

We had seen two birds whilst setting up the nets and assumed the two we caught to be these birds. This may not have been the case however as we later caught two more birds one of which was a female (red base to lower mandible). This was a new ringing species for me and I had only seen one bird previously at the site so it was a welcome catch.

Nicole had ringed Common Kingfisher before in Turkey but it was a new site ringing bird for her as well. One comical thing about Common Kingfisher is when you come to weigh them if you place them on their backs they stay on the scales without flying off.

Shakespeare and his times, new book


This video is called Video SparkNotes: Shakespeare’s King Lear summary.

Simon Basketter in Britain takes a look at a new book that cuts through the mysticism around Shakespeare:

Objects that bear witness to Shakespeare’s restless times

The last thing the eyeball of Edward Oldcorne would have seen was the executioner walking to disembowel him.

That eyeball became a relic. And the crowds who watched his execution in the morning could then go to a Shakespeare play in the afternoon.

Neil MacGregor points out in his new book on William Shakespeare, “A stage is actually called a scaffold, and in Henry V the Chorus uses the word.

“So when Shakespeare stages the gouging out of Gloucester’s eyes in King Lear, it is for an audience who would have seen people being disembowelled and the severed heads on London Bridge.”

There is probably more mysticism about Shakespeare than any other writer. MacGregor, the director of the British Museum, cuts through this. He uses the method adopted in his A History Of The World In 100 Objects—looking at 20 things that give a glimpse into Shakespeare’s world.

They include an iron fork, a wooden model ship, designs for the Union flag, a clock, a pedlar’s trunk and Oldcorne’s preserved eyeball. They reveal much about the audience that watched Shakespeare’s plays, as well as about the works themselves.

Revolution

MacGregor reminds us of the grim economic and social realities of a society racked by wars and the threat of civil war and revolution. It is a society wrestling with new ideas about people’s position in the world.

Shakespeare reflected every aspect of these unsettled times. The model wooden boat is not a toy, but a religious offering—giving thanks for the safe return of James VI from his storm-hampered trip to meet his betrothed, Anne of Denmark.

The book links this to Macbeth’s witches and their power over tempests and sailing ships. Several women from North Berwick were accused of witchcraft, threatening the king’s boat. The wedding party had travelled to the castle at Elsinore—later to be the setting for Hamlet.

The book started as a BBC Radio 4 series, and occasionally it seems as if the transfer to print was a bit rushed. But it brings Shakespeare and his world to life, placing it in its historical context in a fascinating way.

MacGregor explains, “I feel I understand now why whenever there are revolutions Shakespeare is what people turn to. Because whenever a society is on the cusp, about to become something else, they find themselves in Shakespeare.”

A Greenshank fae Aiberdeen to Ireland to Spain

Raymond Duncan writes:

Over 250 Greenshank have been colour-ringed since 2005 in a joint Grampian/Tay RG project investigating the origins, site fidelity and onward movements of birds on autumn passage through the Ythan Estuary (near Aberdeen) and Montrose Basin, NE Scotland. Ten individuals have been resighted in Ireland and four in Spain.

Recent reports of juvenile ‘RL: Light green/blue LL: Blue/black’ have been particularly interesting not only because of the speed of travel but also because it is our first sighting that confirms some birds visit Ireland before re-orientating south to Spain and beyond for the winter. It was ringed as a juvenile on the Ythan Estuary on 11/09/12.

Dermot Breen then resighted and photographed it … 11 days later at Muckrush, Lough Corrib, County Galway, right over near the west coast of Ireland.

He prudently commented that he thought the bird was just passing through as Greenshank aren’t too common at this inland site. How correct he was. Five days later Daniel Lopez Velasco resighted and photographed it … at Ponteceso Estuary, A. Coruna, NW Spain.

Thanks very much to both for reporting these sightings. Please keep an eye out for colour-ringed Greenshank where ever you are. Holiday birders have reported colour-ringed birds in Morroco [sic; Morocco], the Nijer Delta and this regular spring visitor on the Cape Verde Islands.

“Nijer Delta” is probably a misspelling for the Niger Delta in Nigeria. I hope for the greenshanks that they won’t land there on soil polluted by Shell or other Big Oil corporations, killing them.

New threatened wildlife list

Hundreds of plants and animals added to ‘threatened’ list

October 17, 2012, 9:35 pm

HYDERABAD, India – An island-dwelling cockroach and a tiny snail were declared extinct Wednesday while 400 plants and animals were added to a threatened “Red List” as global environment ministers met in India.

The International Union for Conservation of Nature (IUCN) updated its authoritative study on the state of biodiversity on Earth, saying 20,219 species were at risk of dying out.

It added 402 species such as the Egyptian dab lizard and the Sichuan Taimen, a fresh water fish from China, to the “Red List”, which puts them in the threatened category.

Two invertebrates, a cockroach from the Seychelles last seen in 1905 and a freshwater snail called Little Flat-Top from the US state of Alabama, have moved into the extinct category since the last update of the bi-annual survey in June.

“These are species that do not occur anywhere else in the world,” the IUCN’s director of biodiversity conservation Jane Smart said at a UN Convention on Biological Diversity (CBD) conference in Hyderabad, southern India.

The report also showed that 83 percent of Madagascar’s 192 palm species, which the poor rely on heavily for food and housing, are at risk of extinction.

They include the “Suicide Palm“, which grows up to 18 metres (60 feet) in height and dies a few months after flowering and producing seeds. Only 30 mature specimens are known to exist in the wild today.

A quarter of the world’s mammals, 13 percent of birds, 41 percent of amphibians and 33 percent of reef-building corals are at risk of extinction, according to the IUCN.

The report set alarm bells ringing as more than 70 environment ministers met for talks on halting the depletion of Earth’s natural resources, with pressure for them to match political pledges with hard cash.

There was also some happy news, however, with the IUCN saying eight species had moved out of the extinct category due to new sightings.

They include a Tanzanian tree, Erythrina schliebenii, five types of mollusc, a dwarf toad from Sri Lanka, and Holdridge’s Toad, a species from Costa Rica.

The gathering comes two years after UN countries approved a 20-point plan at a conference in Japan for reversing the worrying decline in plant and animal species that humans depend on for food, shelter and livelihoods.

Execution of the plan has been hamstrung by a lack of funding and the Hyderabad talks are being closely watched for new financial commitments.

Environmental economist Pavan Sukhdev said Wednesday that an expert panel had concluded that between $150-440 billion (115 to 330 billion euros) would be needed annually to meet the Japan goals, dubbed the Aichi biodiversity targets.

Current conservation spending is estimated at about $10 billion per year.

With a 2020 deadline, the targets include halving the rate of habitat loss, expanding conservation areas, preventing the extinction of species on the threatened list, and restoring at least 15 percent of degraded ecosystems.

“The cost of inaction is something that people have only just begun to appreciate,” UN Environment Programme executive director Achim Steiner warned.

“When you run out of water, when you run out of arable land… and your rivers run dry, when your lakes silt up, when your fisheries collapse, then it is often too late to start talking about the value of biodiversity ecosystems.”

The three-day ministers’ meeting comes at the end of two weeks of talks by senior officials from 184 parties to the conference — negotiations that delegates say have become stuck on the question of financing in a time of economic austerity.

The convention, to which 193 countries are signatories, marks its 20th anniversary this year.

It has already missed one key deadline when it failed to meet the target set to halt biodiversity loss by 2010.

The updated Red list, assessing 65,518 known species of animals and plants, lists 795 as extinct and 63 as surviving only in captivity.

Ant-eating dinosaurs?


Alvarezsaur family tree

From Dinosaur Tracking blog:

Did Dinosaurs Eat Ants?

If there’s one group of dinosaurs that needs better PR, it’s alvarezsaurs. They’re among the strangest dinosaurs to have ever evolved, yet outside of dinosaur die-hards, few people have ever heard of them. They’re not one of those classic forms–the sauropods, tyrannosaurs, stegosaurs, or ceratopsids–that have been cherished for the past century. Paleontologists only recently began to uncover their bones. Alvarezsaurus itself was named in 1991, but it and its close relatives didn’t quite get swept up in the same wave of dinomania as their other Mesozoic cousins.

Alvarezsaurs weren’t big, toothy, or menacing. That’s part of makes them so special. Alvarezsaurus, Mononykus and their relatives from Cretaceous Asia, South America and North America were small dinosaurs–these feathered dinos ranged from the size of a pigeon to about the size of a turkey. In fact, these dinosaurs were so avian in nature that there was once a debate about whether alvarezsaurs were non-avian dinosaurs or birds that had lost the ability to fly. Since those early debates, numerous studies have confirmed that they were non-avian dinosaurs that were closely related to the strange therizinosaurs and ostrich-like ornithomimosaurs.

But the strangest thing of all is the mystery of what alvarezsaurs ate.

Despite being short, alvarezsaur arms weren’t wimpy. Not at all. Alvarezsaur forelimbs were very stout and included one robust finger tipped in a big claw. (Among these dinosaurs, the total number and development of the fingers varied, but they’re connected by having one finger that was bigger than the others.) In contrast, these dinos often had a reduced number of very small teeth.

Paleontologists thought they saw a connection between these traits and a life feeding on social insects. Mammals such as pangolins and ant-eaters also have stout, heavy-clawed arms and are toothless–a functional pairing that goes with a life of tearing into ant and termite nests to slurp up the scurrying insects in their nests.

Could alvarezsaurs have done the same? So far, it’s the most popular hypothesis for their bizarre nature. In a 2005 paper, paleontologist Phil Senter proposed that Mononykus would have been capable of the kind of scratch-digging needed to rip open social insect nests. Then, in 2008, Nicholas Longrich and Philip Currie described the alvarezsaur Albertonykus in deposits that also contained traces of Cretaceous termites. Alvarezsaurs seemed to have the right equipment and live at the right time to be social insect predators.

But we don’t really know. No one has published any direct evidence that Albertonykus or any other alvarezsaur ate ants or termites. The hypothesis is certainly a reasonable one, but we still need a test of the idea. Fossil feces may eventually hold the answer.

If paleontologists eventually uncover dinosaur dung of appropriate size that contains ants or termites and comes from a habitat shared by alvarezsaurs, that discovery would strengthen the ant-eating hypothesis. A cololite would be even better. While coprolites are petrified feces that have already been excreted, cololites are fossil poop preserved inside the prehistoric creature’s body prior to expulsion. If paleontologists found an alvarezsaur with a cololite containing termites, that would be direct evidence that these dinosaurs truly did snarf down hordes of insects. For now, though, we can only hope that some lucky fossil hunter makes such a discovery.
