Dutch rare birds site is on the Internet


This video is called 30,000-strong flock of Barnacle Geese, Netherlands, February 2010.

On 21 August, I reported about a new Internet site with data about rare birds in the Netherlands, ever since 1800.

Meanwhile that new site is working.

It is here. It is called Dutch Avifauna.

Many things on the site are not working yet (including the English language parts which I expect will be working soon).

Officially, the site will start on 25 August.

More Pakistani civilian drone deaths than reported


This video from the USA says about itself:

Civilian Deaths from US Drone Attacks Much Higher than Reported

Aug 21, 2012 by The Real News

Gareth Porter: New investigative work shows that civilian deaths in Pakistan, including from second wave attacks, [are] higher than [the] Pentagon reports.

On January 3 2010 school teacher Sadiq Noor and his nine-year-old son were blown to pieces in Pakistan by two missiles fired by a US drone into their home: here.

Pakistan Drone Study Finds ‘Damaging And Counterproductive’ Consequences From U.S. Policy; here.

Robert Naiman, Truthout: “If people have to confront the actual reality of the Pakistan drone strike policy – the reality in which its impact is mostly about killing and terrorizing civilians and alienating Pakistani public opinion from the United States as opposed to the fairy tale in which it is all about wasting top-level ‘bad guys’ – the political story will fall apart”: here.

Fukushima fish sicker than ever


This music video from Japan is by Japanese punk rock band Scrap, consisting of victims of the Fukushima nuclear disaster, with the song FUCK TEPCO!!

From Asahi Shimbun daily in Japan:

Radiation 258 times legal limit found in fish off Fukushima

August 22, 2012

Fish containing 258 times the legal limit of radioactive cesium have been found in waters off the crippled Fukushima No. 1 nuclear power plant, the plant operator, Tokyo Electric Power Co., said on Aug. 21.

The reading for two rock trout, caught about 20 kilometers to the north of the plant, showed 25,800 becquerels per kilogram, the highest yet detected in surveys conducted after last year’s nuclear accident.

Consuming 200 grams of the fish would amount to an internal radiation exposure of 0.08 millisievert for a human. The annual safety limit for radiation exposure from food products is 1 millisievert per person.

Fishermen currently do not fish in the waters in question, however, and no rock trout from the area have been distributed to the market.

Tetsu Nozaki, who heads the Fukushima Prefectural Federation of Fisheries Co-operative Associations, expressed concern about the finding.

“The reading was way beyond the levels recorded before,” he said. “It is worrying.”

The finding came after the federation resumed catches of some octopus and shellfish in waters off Soma, in the northern part of the prefecture, between June and early August on a trial basis. Those fish were distributed to markets, including Tokyo.

Nozaki said the federation will make a formal request for TEPCO to find out why such high levels of contamination were detected in the rock trout.

“We operate on the assumption that no additional contaminated water was leaked into the sea from the plant,” he said.

TEPCO officials said there could be so-called “hot spots” at the bottom of the sea where cesium is concentrated because rock trout usually live near the seabed. The company plans to study cesium levels of the crabs and the shrimp that rock trout feed on.

In a survey conducted in April last year, 14,400 becquerels per kilogram was detected for sand eel caught off the coast of the prefecture.

In March, landlocked salmon in the Niidagawa river near Iitate, a village to the northwest of the plant, measured 18,700 becquerels per kilogram.

New Indonesian rat species discovery

From DISCOVER Magazine:

Newly discovered rat that can’t gnaw or chew

If you only looked at mammals, you could reasonably believe that the chisellers have inherited the earth. Of all the various species of mammals, forty percent are rodents. Rats, mice, squirrels, guinea pigs… all of them have the same modus operandi. They gnaw their way into their food with self-sharpening chisel-like teeth.

Whether tiny gerbil or huge capybara, rodents eat with the same special teeth. The upper and lower jaws each have a single pair of incisors that grow continuously through their lives. The front of each tooth is made from hard enamel, while the back is made of soft dentine. As the rodent gnaws, the incisors scrape at each other, and the dentine wears away faster than the enamel. This creates a permanently sharp edge, useful for cracking into wood, nuts and flesh alike. Once gnawed, the rodent passes its food to the back of their mouths to be chewed by grinding molars.

But on the Indonesian island of Sulawesi, Jacob Esselstyn has discovered a new species of rodent that radically departs from this universal body plan: a “shrew-rat” that he calls Paucidentomys vermidax.Its name –a mash-up of Latin and Greek—gives a clue to its lifestyle. It means “worm-devouring, few-toothed mouse”.

The shrew-rat is just a few inches long, with small eyes, large ears, and a soft coat. Its most distinctive feature, however, is its long snout, reminiscent of the distantly related shrews that it is named after. At the end of the snout, the lower jaw has the usual flat-edged incisors, but the upper jaw has a pair of bicuspids (like the ones next to your pointed canines). And that’s it. Unlike every other rodent, this one has no molars—just four incisors, nothing else.

There are other shrew-rats in Indonesia and the Philippines, and while all of them have lost the ability to gnaw, none have features quite as extreme as Esselstyn’s new find. (All of them, for example, have molars.) They’re an odd group, united by their common long-snouted appearance rather than by any evolutionary similarities. Rather than forming one unified branch of the rodent family tree, the shrew-rats represent twigs on separate branches. They evolved their odd shapes independently.

Shrew-rats typically eat earthworms and other soft-bodied creatures that don’t require gnawing teeth. That’s exactly what Esselstyn’s new species does. He collected two of the animals in March 2011, and when he examined the stomach contents of one, he found earthworms and nothing else.

Esselstyn thinks that the shrew-rat has lost the ability to chew and gnaw because it only eats soft prey. It only needs teeth for capturing food rather than processing it. As such, it has lost everything except for two front incisors, used to snag worms and cut them into easy-to-swallow pieces. Like the lost limbs of snakes and whales, the missing teeth of the shrew-rat are a reminder that evolution disposes of body parts that are no longer useful, and that those same losses can open up new opportunities.

Siberian flowers from Ice Age fruit

From DISCOVER Magazine:

After 32,000 Years, an Ice Age Flower Blooms Again


Permafrost is like nature’s freezer.

by Eric A. Powell

Deep in the frozen tundra of northeastern Siberia, a squirrel buried fruits some 32,000 years ago from a plant that bore white flowers. This winter a team of Russian scientists announced that they had unearthed the fruit and brought tissue from it back to life. The fruits are about 30,000 years older than the Israeli date palm seed that previously held the record as the oldest tissue to give life to healthy plants.

The researchers were studying ancient soil composition in an exposed Siberian riverbank in 1995 when they discovered the first of 70 fossilized Ice Age squirrel burrows, some of which stored up to 800,000 seeds and fruits. Permafrost had preserved tissue from one species—a narrow-leafed campion plant—exceptionally well, so researchers at the Russian Academy of Sciences recently decided to culture the cells to see if they would grow. Team leader Svetlana Yashina re-created Siberian conditions in the lab and watched as the refrigerated tissue sprouted buds that developed into 36 flowering plants within weeks.

This summer Yashina’s team plans to revisit the tundra to search for even older burrows and seeds.

The flowering plant of this article is Silene stenophylla.

Spoonbills and goldfinches


This video is about Polders bij Poelgeest nature reserve in the Netherlands and the birds which live there.

Today, I went there again.

Gadwall ducks in the canal near the entrance.

Someone tells me that recently an adult and a juvenile spotted crake have been seen. I did not see any spotted crake myself today.

Spotteed crake photos: here.

I do see a great crested grebe in the next canal.

One canal further: teal.

In the southern lake: coots. A common tern flying. A Canada goose. A grey heron. A shoveler duck swimming.

Edible frog sound.

On a muddy islet, a moorhen passes a snipe.

Then, the northern lake. Four spoonbills resting on the biggest island.

On a smaller muddy island a lesser-black-backed gull, six black-headed gulls, and a common tern.

Two greenshanks standing in the water. Will their autumn migration bring them to Portugal? To the Gambia?

In the canal near the railroad: two adult great crested grebes with a youngster, about half their size.

A grey lag goose along the footpath.

A bit further, a blue-tailed damselfly sitting on grass along the path.

Meanwhile, three of the spoonbills are searching for food in the water together. The fourth one is still on the island, cleaning its feathers.

In the trees just past the northern bench, a twittering group of goldfinches, mostly juveniles. Over twenty of them.

Along the big canal, Egyptian geese.

As I walk back, a lapwing on a muddy southern lake island.
