Swedish soldiers discover bones of a giant

‘In 1645, the twenty-seventh year of the Thirty Years War, Swedish armies inflicted a devastating blow to the Imperial forces in Bohemia and swept into Austria with the aim of capturing of Vienna. The Imperial capitol, was not prepared to give up easily. The Swedes soon found themselves digging in for a long seige, negotiating with allies for support, and building fortifications around the occupied countryside. Upriver from Vienna, in the Krems district, while digging trenches, a group of Swedish soldiers discovered the bones of a giant….

Discover the teeth of giants. And say Happy Blogoversary to John.

Senate Vote on Keystone Imminent

This just in from Jason at 350.org:

Friends,

The moment is here: about an hour ago, some of big oil’s best paid Senators filed an amendment supporting construction of Keystone XL to the Senate’s budget bill.

Our goal today is to keep the Senate from forcing Obama to approve the pipeline. The oil industry is using all their money and might to push Keystone, but we’ve stopped them before, and we can do it again.

Many of us called our Senators once already this week to stop the pipeline, and it made an impact on big oil’s vote count. One of the people that big oil needs to support this bill is Senator Amy Klobuchar from Minnesota — and since this vote will come down to the wire, they’re doubling down with pressure.

The vote could come in a matter of hours — can you call Sen. Klobuchar before the vote to tell her to stop the pipeline?

Here’s the number to use:

Sen. Klobuchar – (202) 224-3244
Then, click here to report what you heard and share this news: act.350.org/call/kxl-march-22-2013/

And here’s a suggestion for what to say when you call today:

“Hi, I’m calling to oppose the Keystone XL pipeline amendment that was just introduced to the budget. The science is settled: this pipeline is a climate disaster, and I insist that the Senator oppose this or any other attempt to force construction of the pipeline.”

In a close fights like this, calls from passionate constituents play a key role in helping Senators decide which way they will vote. Calls now will stiffen the spines of Senators who may be weakening, and get others off the fence.

This pipeline is a climate disaster, which is the reason that hundreds of thousands of Americans have taken action to stop it. If you’re a part of that number, you already know the stakes. It’s time for our supposed leaders to get serious about climate change and stop the pipeline.

Thanks for calling — I’ll have an update after the vote,

Jason

The Climate Hockey Stick is Wrong!

This is a hockey stick:

hockeystick

This is the Grim Reaper’s Scythe:

sythe

This is global temperature over the last 10,000 years projected into the immediate future using good scientific estimates:

Carbon-Final

You decide. Should the Hockey Stick be replaced with the Grim Reaper’s Scythe?

A new study of Natural Selection in Birds

…there is a new study that has significant advantages of the Bumpus study, though the latter will still be useful in teaching about evolution because of its limitations and the questions it raises. The new study is about Cliff Swallows (Petrochelidon pyrrhonota) in southwestern Nebraska.

As you know, a lot of birds are killed in the U.S. because of collisions with vehicles. About 80 million, according to the Cliff Swallow study by Charles Brown and Mary Bomberger Brown. Brown and Brown examined the possibility that birds in a population subject to this particular form of mortality would undergo Natural Selection, with some traits that prevented death through vehicular collision being selected for over time. …

Golden Eagles and Free Coffee!

You’ve heard of the The Crossley ID Guide: Eastern Birds (The Crossley ID Guides). It is a revolutionary new way to assemble a field guide, where each page has a drawing of what it would look like if suddenly outside your living room there was a full blown habitat for some species of bird, with individuals from that species flying or sitting all over the place in different positions, doing different things, and at different distances. These pages in the field guide almost give you the experience of having seen many of this partiuclar species of bird, like you were suddenly an experienced birder. In preparation for a birding trip, you can prepare by going over the birds you hope to see, and during or after the trip you can use this guide to check your ID’s.

Well, now, there is also the The Crossley ID Guide: Raptors. This is the same thing but for Raptors. The book is coming out RIGHT NOW so Princeton has organized a major blogging tour, and right now, you’re on the tour! The other blog posts are as indicated here, on this schedule. I recommend visiting all the other entries. Some of them are giving away prizes, so especially check those out.

As a matter of fact, we’re giving away a prize here, right now, on this blog post, and you may be able to win it. Details are below. But first, a word about ….

… Golden Eagles …

Golden Eagles are a bit of a sore spot with me because they are rare and said to be hard to distinguish from immature Bald Eagles. This is not their fault. But when one claims to have seen a Golden Eagle the automatic reaction among most birders is to claim that you are wrong, that it was an immature Bald Eagle you had seen. This is especially true in Minnesota. If you look at bird books, they are sometimes not shown to be here at all, even as migrants, or otherwise, only rarely.

Stan Tekiela’s Birds of Minnesota Field Guide, Second Edition does not even list Golden Eagles. The Smithsonian Field Guide to the Birds of North America shows northern and central Minnesota as a migratory route, but the rest of the state is indicated as “rare.” Birds of Minnesota and Wisconsin indicates them to be an uncommon migrant or winter visitor in parts of the region. The Birds of North America and Greenland: (Princeton Illustrated Checklists) shows them as occassional winter visitor in only a small area to the West of Minnesota. National Geographic Field Guide to the Birds of North America, Sixth Edition shows them only rarely in Minnesota, but more in the eastern part of the state. Hawks and Owls of the Great Lakes Region and Eastern North America shows them as an occasional winter species in Minnesota and a very large area of the plains and the eastern US.

The Kaufman Field Guide to Birds Of North America shows them totally absent in the state, but this book also has another interesting geographical observation. There is a huge area of eastern Canada with a dotted line around it indicating that they may or may not breed there. This is an interesting thing about Golden Eagles. When you look into it, you find that there is this large not very mountainous region in which this mountain bird seems to breed, migrate to and from, but is not observed within. Like they were hiding out there. The Birds Of The Great Plains shows them rare in Minnesota and more common to the west than the east.

Of course, one always wants to consult the bible in these matters. The Peterson Field Guide to Birds of North America (Peterson Field Guides) shows them totally absent in Minnesota, but also indicates the big mysterious region to the north where they may or may not breed.

Now that we’ve established that there is no agreement whatsoever on the distribution of, timing of, or even existence of, the Golden Eagle in Minnesota, let me tell you about two of our sightings of the bird (there’s been a few but these two are particularly interesting).

The firs sighting was about 10 years ago. Julia was about seven, and we were visiting the Minnesota Raptor Center in Falcon Heights. We were being given a tour of the cages, where various raptors were kept. These birds were all rescued from somewhere, generally with injuries. Some would be rehabilitated and released. Some would become ambassador birds, traveling around the area with experts from the Raptor Center for educational purposes. Some would simply remain in the cages forever.

As the tour progressed, the tour guide would say a few things about each bird as we approached the cage, then we would look at the bird for a while, then move on to the next cage. At once point, she said, “And here is the Golden Eagle. There are no Golden Eagles in Minnesota, not at all. If you ever think you are seeing a Golden Eagle, I assure you that it is merely an immature Bald Eagle. There are no Golden Eagles in this state.”

Then, as we stopped in front of the cage to look at the bird, Julia pointed to it and said, “There’s one!”

“What?” the guid said.

“There’s a Golden Eagle. It’s in Minnesota. So you’re wrong.”

I was fully expecting to find, on further inquiry, that this particular bird had been found injured along the highway in some other state and brought here to the Minnesota Raptor Center for treatment. So, I asked, “Where is this bird from?”

We were given a very precise location, along a road near a particular town. In Minnesota. In fact, within a one hour drive from where the bird was sitting in the cage. So, there you go.

The second sighting was up at the cabin. It was early fall and we were sitting on the deck overlooking the lake, to the north. Although we were located a short distance outside the Chippewa National Forest, which is known to have the highest number and highest density of Bald Eagles in the US outside of Alaska, the tree line across the lake was in the forest proper, and in fact, this was an excellent place to see bald eagles. A nesting pair lived in sight just a few hundred yards to the left, and hunted in this bay. Sometimes other eagles came by, and the pair often had a young one. If you want to see a bald eagle from that spot, all you had to do is look. If the eagle was not visible that instance, all you had to do was listen and you’d hear either the eagles themselves or some other bird complaining about the eagles. Indeed, that is the main reason for the local loons to holler. If you hear the loon going loony just look up. There will be one or two bald eagles reeling at altitude over the loon, sharing the fishing grounds.

Anyway, we were sitting there looking north when suddenly there appeared over the tree line to the north, across the lake, a bird that was clearly a very large eagle, and it was flapping its wings in powered flight going in a straight line right for us. We knew it was an eagle because of its shape and size. However, it was significantly larger looking than any of the bald eagles in the area. I should note that despite the large number and high density of eagles in Chippewa Forest, these Bald Eagles are smaller than the Alaskan kind. But this bird was whopping big.

Also, it was flying funny. Not only was it not soaring as eagles tend to do, it was flapping its wings in what looked like an unusual pattern. And, it was not a bald eagle. As it got closer, we watched it with binoculars and could see the field markings very clearly.

“That was a Golden Eagle, wasn’t it?” I said to Amanda.

“I guess so,” she replied.

“You could see a bit of white on the upper wings before it came over us.”

“Yeah, I saw that. You could see white on its tail shinning through with the sun.”

“It had a small head.”

“And a smaller bill.”

“I know, and that color was different than an immature Bald Eagle.”

“When it stopped flapping for a while its wings almost looked like a vulture.”

“I know. All the field markings seem to suggest a Golden Eagle, not an immature Bald Eagle.”

“Yeah, and you know what,” Amanda said.

“What?”

“We know what an immature Bald Eagle looks like. That wasn’t one of them.”

And now it’s your turn. The following illustration shows several raptors. Each is labeled with a letter. Some of these raptors are Golden Eagles, some are not.

EagleQuiz

Your job is to identify the Golden Eagles. Put a set of letters that represent only Golden Eagles in a comment. I will collect all the perfectly correct answers and send them to Price Waterhouse in a briefcase, where one of the correct answers will be randomly selected.

If you use a proper email address when you sign in to comment, then I’ll be able to contact you if you are chosen. Otherwise I’ll just mark the correct and chosen comment here on this blog and you can check back later, and if you were the winner we’ll work out how to send you your prize, provided by Princeton University Press.

The prize will be two pounds of Birds and Beans Coffee! It will be sent to you by the good people of Princeton.

Also note that Princeton has a contest in which you can win a pair of Nikon 8220 Trailblazer 8×42 ATB Binoculars and some autographed bird books. Details are HERE.

Happy Birding!


We’ll pick the winner on April 1st.

Lonesome George To Be Embalmed

I’m not sure if it is really called “embalmed” when done to a tortoise, but it is the same idea. Lonesome George was a Galapagos Tortoise, Chelonoidis nigra abingdonii, who was known for some time a the last living individual of his subspecies. He lived on Pinta Island in the Galapagos. He died on my birthday last year at the age of “more than 100 years old.” These tortoises numbered over a quarter of a million a few centuries to just a few thousand today.

The latest news is that George will be embalmed, or preserved, at the Museum of Natural History in New York City and returned to the Galapagos at a later time.

A 2007 study of the genetics of Galapagos Tortoises (with this followup) suggests that George is not really the last of his kind. There are over a dozen others! It turns out that the tortoises on this particular island are genetically diverse and have relatives on other islands, as a result of natural and human-caused dispersal of the animals.

Did Giorgos Katidis flash a Nazi salute or not?

By now you’ve probably heard the story, seen the pictures, and watched the video. If not:

The 20-year-old Katidis gave a Nazi salute after scoring the go-ahead goal Saturday in AEK’s 2-1 victory over Veria in the Greek league. He pleaded ignorance of the meaning of his gesture – right arm extended and hand straightened. He claimed on his Twitter account that he detests fascism.

Giorgos Katidis

This looks like a game of “shirts” vs. “skins” but that is because the exuberant soccer player ripped his shirt off just before doing the stiff-arm gesture. Here’s the video:


Ο χαιρετισμ?ς του Γι?ργου Κατ?δη! by kokoretsi

The most current info I have seen indicates that Katidis is now banned from his team for life. Other sanctions may be imposed as well. Yet, he claims that he did not know what he was doing, and his coach claims he was very upset and crying in the locker room after finding out people’s reactions.

As you know, the whole Nazi thing is Greece has been an issue lately. It is hard to believe that a guy living in Greece would not know anything about this, and that anyone growing up in western society, especially in Europe, would not know about Nazis and Nazi salutes. Personally, I have no opinion on whether or not he knew what he was doing. If you look at the picture, it is “clearly” a Nazi salute, but if you look at the film, it may be a bit more ambiguous. He was in a state of high emotion. He ripped his shirt off and was flailing around and getting jumped on and stuff. The still picture looks very different from the video, but either one could be interpreted rather negatively. Having said that, I’m reminded of this picture of me:

Greg Laden not giving a Nazi Salute in South Africa
This is me at Augrabies Falls National Park, South Africa.

In this picture, I’m standing in South Africa looking north towards Namibia. I’m explaining the geology to very interested onlookers, and at this particular moment I’m indicating the high ridge we see in the distance that forms the southern edge of the broad plateaux on which the Kalahari Sands rests. Here’s the plateaux, and you can see that it is far away and flat, thus the particular hand gesture I’m using:

Looking towards Namibia from  South Africa
The view across the Gariep (Orange) River, South Africa, looking North towards Namibia.

Since this is a picture of me in the field I used it for a while on the site 10,000 Birds where I write a monthly column. I thought it appropriate because it was me outside explaining stuff.

I’m not sure why anyone would legitimately think that I was giving a Nazi salute in this picture, or that I, an anti-racist anti-Nazi anthropologist who shares many salient features with Indian Jones (notice that in the picture I’ve got a sack like his, also, I often say “Nazis … I hate those guys” but I am not afraid of snakes to the extent he is) would ever do so. In fact, the Greek Nazi Party itself identified me as “The Antichrist” last year, and posted a whole blog page just on that. Nazis don’t like me any more than I like them. Also, why would I put a picture of myself making a Nazi salute on a web site about birds? Anyway, people who hate me on the Internet (bad people, I assure you) saw this picture and spread around that I was a Nazi, and that this was the proof. The picture sucks anyway, so I took it off. I suppose that makes me a crypto-Nazi to some.

One possible test of Giorgos Katidis intention, though it would be indirect, might be an examination of his tattoos. If he’s got a few swastikas permanently engraved on his body, then it is more likely that he was flashing the Nazi salute, right?

I’m glad the Greeks, and the sport, are alarmed and concerned about Nazi symbols. I’m not sure what the right thing to do in this case, though.

Does Fracking Mess Up our Water Supply?

Fracking, or Hydraulic Fracturing, is a method of extracting hard-to-get oil and gas from shale. For the most part, fossil fuels originally formed in shale, which was in turn laid down by near surface life in anoxic seas. Sunlight powered a high turnover of near surface plankton, algae, and bacteria, but oxygen-poor conditions just a little deeper in the sea made it unlikely for much of that life to be recycled through other life forms. So, during periods of anoxic seas, which lasted for millions of years now and then in earth history, much of that organic material from near the surface of the ocean settled into the sea floor mud where it became buried and incorporated into the growing layers of sediment. This was eventually transformed into oil and gas rich shale. (For a detailed overview of that aspect of earth history, see this fascinating book.) Eventually, some of that oil and gas collected in deposits that could be easily removed through drilling. Once this oil and gas is removed, however, the remaining hydrocarbon fuels are much more thinly distributed in the shale. In order to access this fuel, modern day miners pump water mixed with sand and chemicals at high pressure into the shale, which causes it to fracture, allowing the gas and oil to accumulate and become more easily removed. It is a little like squeezing a few drops of the water out of a mostly dry sponge…
