NASA Press Conference Will Announce Voyager Captured by Alien Craft!

I’m kidding, I’m kidding, NASA did not say that. But I do think people need to take it down a notch with this whole blaming NASA for doing their press conferences wrong. As far as I know, the Curiosity Martian Laboratory Robot recently approached a non nondescript pile of dirt, analyzed the bejesus out of it as a test of the fancy dancy instruments on board, and everything worked. The pile of dirt was not interesting but they did to that pile of dirt what would have required 3,000 feet of laboratory floor space full of expensive equipment and a dozen technicians working for two months back in the day. But they did it with a Robot. On Mars. In a few days. And everything worked.

If you don’t think that is overwhelmingly exciting than you are either dead or have no idea how science works. That is incredibly amazing wonderful news.

So, when a NASA scientist became exuberant over the news that would be reported in the upcoming press conference and said he was really excited, science reporters and bloggers, jaded by the Mono Lake affair no doubt, assumed that only one thing could be that exciting: Martians. Nothing else. And then, when “rumors” went around suggesting that it was probably not Martians, it became time to crucify NASA again. That is not good science reporting, people. Don’t think you’re doing it right and NASA is doing it wrong.

I also think that the spoof site reporting that a blue plastic necklace had been found on the Angry Red Planet was pretty funny, and I think that NASA having that site killed was unnecessary. Those details are here.

Take it down a notch, people.

OK, there really will be a V-ger press conference and a Curiosity press conference in the near future.


Actually, NASA has press conference all the time. All the time. They’ve been doing this for years. The sudden concern that NASA is doing science by press conference, if it is a real concern, should have been brought up a long time ago. But really, there should not be a concern. The data that are collected on these various NASA Big Science Missions are studied by real live scientists who publish the results in peer reviewed journals. But they also have the press conferences.

Think about this for one minute. What if NASA had the rule that nothing they did would be reported to the press, but rather, only released via peer reviewed journals, often years after the actual mission activities were carried out, but they’d also let you stand a few miles away and watch launches. That’s it. No press conferences keeping people updated on the various missions as they reach various milestones. What would the people who watch this science and report on it and blog about it do then? They’d whinge about the lack of transparency, the lack of information, they’d say things like “Sure, sure, peer reviewed papers are great, but with this kind of science, with the huge public funding, and given the importance of the public interest, and the various milestones and stuff … well, they should have press conferences now and then, dammit!”

Yes, that is what would be said.

So, here, I will present the information on the upcoming press conferences, as provided by NASA, so you can see what it is all about.

Update Set In San Francisco About Curiosity Mars Rover

PASADENA, Calif. — The next news conference about the NASA Mars rover Curiosity will be held at 9 a.m. Monday, Dec. 3, in San Francisco at the Fall Meeting of the American Geophysical Union (AGU).
Rumors and speculation that there are major new findings from the mission at this early stage are incorrect. The news conference will be an update about first use of the rover’s full array of analytical instruments to investigate a drift of sandy soil. One class of substances Curiosity is checking for is organic compounds — carbon-containing chemicals that can be ingredients for life. At this point in the mission, the instruments on the rover have not detected any definitive evidence of Martian organics.

The Mars Science Laboratory Project and its Curiosity rover are less than four months into a two-year prime mission to investigate whether conditions in Mars’ Gale Crater may have been favorable for microbial life. Curiosity is exceeding all expectations for a new mission with all of the instruments and measurement systems performing well. This is spectacular for such a complex system, and one that is operated so far away on Mars by people here on planet Earth. The mission already has found an ancient riverbed on the Red Planet, and there is every expectation for remarkable discoveries still to come.

Audio and visuals from the briefing also will be streamed online at: .

NASA to Host Dec. 3 Teleconference About Voyager Mission

November 29, 2012

PASADENA, Calif. — NASA will host a media teleconference at 11 a.m. PST (2 p.m. EST) on Monday, Dec. 3, to discuss the latest findings and travels of NASA’s Voyager 1 spacecraft.

Voyager 1 and its twin, Voyager 2, have been speeding through the outer reaches of our solar system and sending back unprecedented data about the bubble of charged particles around our sun. They were launched in 1977 and have traveled farther from Earth than any other spacecraft.

Audio and visuals of the event will be streamed live online at: .

Is Bullying A Feature Or A Bug?

This looks interesting: The No Asshole Rule: Building a Civilized Workplace and Surviving One That Isn’t.

This is the description of the book:
The No Asshole Rule was awarded a Quill Award as the Best Business Book of 2007.

When Robert Sutton’s “No Asshole Rule” appeared in the Harvard Business Review, readers of this staid publication were amazed at the outpouring of support for this landmark essay. The idea was based on the notion, as adapted in hugely successful companies like Google and SAS, that employees with malicious intents or negative attitudes destroyed any sort of productive and pleasant working environment, and would hinder the entire operation’s success.

Now using case studies from these and many more corporations that have had unquestioned success using variations of “The No Asshole Rule,” Sutton’s book aims to show managers that by hiring mean-spirited employees – regardless of talent – saps energy from everyone who must deal with said new hires.

FEATURING A NEW CHAPTER ON THE RULE AND ITS SURPRISING IMPACT! In this new version of The No Asshole Rule, Bob Sutton provides an uproarious account of the world-wide reaction to his best-selling book. As he writes: “I didn’t plan it. I never wanted it. I didn’t believe it at first. And it still make me squirm.” Sutton’s talking about having been branded as “the asshole guy.” But beyond the initial shock value of the provocative title, Sutton’s epilogue goes on to detail the kind of impact this important book has had on corporate organizations and employees everywhere. His book has provided a major wake-up call to those individuals in the business world and beyond who somehow have lost sight that a little civility goes a long, long way when it comes to dealing with our fellow human beings – and leading an effective organization. This is one epilogue that is definitely worth reading.

There is a blog post discussing this here:

The 7 Ways Organizations Justify Bullying in The Workplace

…The potential for individuals within organizations to behave unethically is limitless. Unfortunately, this potential is too frequently realized. If these types of incidents are dealt with in the heat of the moment, not only can they be corrected immediately but you also send a signal throughout the organization that this will not be tolerated. It is like a pebble tossed into the water that sends out larger ripples.

Bullying in school is the training ground for bullying in the organization….

Shall we discuss the Internet?

Hat Tip: Amanda Temple

Taking Lego to the Max

Huxley’s Aunt and Uncle have given him, as Christmas and Birthday presents, various kits to make Imaginarium style train setups. Imaginarium is like Brio and Thomas the Tank Engine, but generally available as a Toys R Us Brand. He has enough cool bits and pieces to make a kind of double figure eight layout, but the ends can’t ever be closed into a continuous loop because we don’t have enough pieces of track. Or maybe we do. We keep trying different configurations but it never works. It also may be the case that while Huxley, Amanda and I make great Train Engineers once the tracks are set up, we make lousy Civil Engineers when laying them out. We need to hire a consultant.

This is the same problem with Lego. You see all these amazing Lego things people put together … especially if you go to Lego Land at the Mall of America across town from here. But, when you start putting this stuff together, at first, it is hard to do because everything really has to be just right to make it work, especially if electronic motors and gears and stuff are involved.

You can learn to make great Lego thingies through extensive trial and error, or you can hire a Lego consultant, or you can just get these books by Yoshihito Isogawa. I’ve got two of them (I think there may be three or four in total): The LEGO Technic Idea Book: Simple Machines and The LEGO Technic Idea Book: Wheeled Wonders.

These are very smart books. There are no words in them, just a few on the cover and in the very beginning. It is all pictures, some of which I’ve pasted here to give you an idea.

The different types of blocks in a given picture are always different colors so you can easily see what is what. There are icons that tell you what kind of assembly you are looking at, and what principle is being illustrated, such as “turning” or “a door” or “putting something in or on something” and that sort of thing. As far as I can tell, it is pretty much one assembly per layout (two pages facing each other) with several angles and other helpful illustrations on each layout. The idea is that you can build the thing that is depicted by looking at what the illustrations (mainly photographs) show, and when you do so, you learn something about how Lego assemblies are made.

The books are divided into parts and chapters. So for the Wheeled Wonders book, Part 1 has Motorcars, Cars that Spin Something, Cars that Move something … Part 2 has Differential Gears, Steering, Suspension … Part 3 has Combining Vehicles with Different Bases, Reversing After bumping a Wall, Using Pullback and Windup Springs … Part 4 has Transmission and a special section called Cool Cars. Clearly, you can see the pattern: Increasing complexity as you move through the book, with later chapters building on earlier ones.

The Simple Machines book has too many chapters for me to name them all, but it starts wiht basics (Gears, Shafts, Turntable, Angled Gears, Womr Drives, etc.) then covers power and motion (Chains and Treads, Rubber Bands, Rack and Pinion, etc.), then motors, more complicated chassis, doors, pulley systems, and eventually, amazingly, provided diagrams with instructions to make a couple of musical instruments.

The author, Yoshihito Isogawa, of Tokyo, is a Lego master and has written a whole bunch of books like this. Imagine having that job!

I think the idea here is that you build from the examples, mainly working from simple to complex, until you find yourself anticipating what the instructions would say, and eventually getting to the point where you don’t need them at all. Thereafter you’d probably find these volumes handy as references in your Ultimate. Geek. Library.

Major weather in the American West?

There are these things called “Atmospheric rivers.” They are big long things up in the air that are loaded with water vapor, and much of the rain and other precipitation we experience comes out of them. This is notable when one of these rivers is extra wet, and there is an extra wet one out West in the US.

The Sierra Nevada range will be accumulating something like 16-20 inches of rain, but where that translates into snow, it will be up there in the 12 foot range, maybe more. There will be a very significant risk of flash flooding north of Sacremento and places in northern California and Oregon are going to get very very wet. The Bay Area will see lots of rain but mostly to the north, in Marin County.


A significant rainfall event is underway across portions of the West Coast as unrelenting Pacific moisture slams into the region. Northern California and southern Oregon will see the greatest rainfall totals of 10 to 20 inches by early next week. Strong winds and mountain snow will also impact the area.

The reason I mention this at all (those of you who live there, I’m sure, are totally up on this) is the following: This sort of excess rain is exactly what we expect to see more often because of global warming. This is the effect that global warming has on the hydrological cycle. It fills the Atmospheric Rivers with more moisture than would otherwise develop in them.

First close up of DNA ever

When Bill O’Reilly said that you “can’t explain tides” I laughed. Why did I laugh? Because if he wasn’t such a dumb-ass he could have EASILY named a dozen thing that science claims to “know” that a reasonably good rhetorician could convince the average Tea Bagger that science really can’t “know” because it can’t really “see” them. The tides have been understood not only by science by by a lot of regular working class potential Republicans (though many are not) who eek out their living on the shores of the briny sea. Bill O’Reilly must have looked like a complete idiot to them. Meanwhile, almost everything we know about the details of what happens inside a cell is either invisible or so close to invisible that it would qualify as “If we can’t even see it, how can we now that?” material.

Of course, we DO KNOW that stuff. It just isn’t easy to know. I’ve discussed that at some length here.

But now, one of the interesting inferences that science has made about something very tiny inside (usually) cells has been confirmed by direct observation, back in the early 1950s in a paper by these guys named Watson and Crick, has been confirmed by sight. A research team in Italy has produced a snapshot, a photograph, of the DNA Double Helix. Sort of.

It looks like this:

From the paper's Abstract: Direct imaging becomes important when the knowledge at few/single molecule level is requested and where the diffraction does not allow to get structural and functional information. Here we report on the direct imaging of double stranded (ds) ?-DNA in the A conformation, obtained by combining a novel sample preparation method based on super hydrophobic DNA molecules self-aggregation process with transmission electron microscopy (TEM). The experimental breakthrough is the production of robust and highly ordered paired DNA nanofibers that allowed its direct TEM imaging and the double helix structure revealing.

Pretty cool, huh? What you are actually looking at is a set of DNA strands wrapped in a very orderly fashion around a single strand that forms a core for the others. You’d have to squint really hard to see the actual double helix, but it is in there somewhere.

In order to get this picture, a strand of DNA was stretched between two pillars of nanoscopic cilicone. The surface that included the nano-pillars was designed to be hydrophobic, which caused the DNA to be left stranded (ha ha) at the super microscopic level so instead of getting all bunched up a single strand could be located. The photograph is sort of an electron microscopic image, but with technology made just for this setup. This technique is a whole new way of visualizing tiny stuff. Keep an eye on the nano silica pillar technique.

There is an article here in the New Scientist as well.

…at present, the method only works with “cords” of DNA made up of six molecules wrapped around an seventh acting as a core. That’s because the electron energies are high enough to break up a single DNA molecule.

Using more sensitive detectors that can respond to lower-energy electrons should soon allow the team to see individual double helices, and even unwound single strands of DNA. “With improved sample preparation and better imaging resolution, we could directly observe DNA at the level of single bases,” says di Fabrizio.

Ice Loss at Poles Is Increasing, Mainly in Greenland

From NASA:

PASADENA, Calif. – An international team of experts supported by NASA and the European Space Agency (ESA) has combined data from multiple satellites and aircraft to produce the most comprehensive and accurate assessment to date of ice sheet losses in Greenland and Antarctica and their contributions to sea level rise.

In a landmark study published Thursday in the journal Science, 47 researchers from 26 laboratories report the combined rate of melting for the ice sheets covering Greenland and Antarctica has increased during the last 20 years. Together, these ice sheets are losing more than three times as much ice each year (equivalent to sea level rise of 0.04 inches or 0.95 millimeters) as they were in the 1990s (equivalent to 0.01 inches or 0.27 millimeters). About two-thirds of the loss is coming from Greenland, with the rest from Antarctica.

From the abstract of the paper:

We combined an ensemble of satellite altimetry, interferometry, and gravimetry data sets using common geographical regions, time intervals, and models of surface mass balance and glacial isostatic adjustment to estimate the mass balance of Earth’s polar ice sheets. We find that there is good agreement between different satellite methods—especially in Greenland and West Antarctica—and that combining satellite data sets leads to greater certainty. Between 1992 and 2011, the ice sheets of Greenland, East Antarctica, West Antarctica, and the Antarctic Peninsula changed in mass by –142 ± 49, +14 ± 43, –65 ± 26, and –20 ± 14 gigatonnes year?1, respectively. Since 1992, the polar ice sheets have contributed, on average, 0.59 ± 0.20 millimeter year?1 to the rate of global sea-level rise.

The melting since about 1992 to the present has contributed to about 0.44 inches of sea level rise (about a fifth of the sea level rise over that period, and there was sea level rise prior to 1992 as well). The main outcome of this study is to clean up the predictions from previous models with much better data and to narrow down the best predictions for future melting. Also, the pace of ice loss now is greater than it was at the beginning of the study period, 20 years ago. Greenland is losing ice about 500% faster now than it was in the early 1990s, while Antarctica is losing ice at about the same rate now as it was then.

Using ScreenFlow and the Reverse Classroom

Next Fall, I will probably try something new in teaching an intro Biological Anthropology course: The Reverse Classroom. This is an idea that is being increasingly applied in High School settings. The simplest version of this idea is that classroom lectures are converted to an on line resource that the students access on their own time, and what would have been study or homework time is done in the classroom. In reality it is a bit more complex than this, because a “lecture” converted to an on line resource may, and probably should, be very different than an in-class lecture, and the activities that are done in the classroom would not consist of students sitting by themselves reading or doing some sort of work. The on line “lecture” would be broken into smaller-than-lecture bits, and involve more interactive tools, and the in-class activities would involve more group activities and tutorials. Also, I don’t intend to create a fully reversed classroom; I’ll use this technique for parts of the course, distributed across the semester.

Pursuant to this, I’ve been looking at tools to help make this work, and on the advice of Peter Sinclair, famous for his most excellent climate science related videos, I’ve obtained a demo copy of ScreenFlow
icon. ScreenFlow works on an iMac. It allows one to specify a window or screen to capture, while at the same time (optionally) to record video and audio off of the hardware built into the computer. So, for example, one can make a Libra Office Impress or Keynote
icon presentation, then “film” oneself giving the presentation. Your head, talking, and your voice are then joined with the presentation you are running through. Your talking head can be in a little box in the corner, the box can be moved, or it can be made invisible. Aside from the presentation itself, one can add text box overlays or other graphic elements. There is even a facility to have a text-to-speech insertion, so I can have a computerized voice read off part of the presentation, though I’m not entirely sure yet why I would do that. Maybe I can make a virtual heckler.

One can also get entirely out of the “presentation” (read “PowerPoint”) mode as well, by simply recording the display of graphics via a file viewer, or for that matter, PDF’s. I’ve done this sort of thing as a lecture tool to some effect. Using this method, instead of showing a presentation on screen in a lecture context, you show your computer’s desktop on which there are various files, perhaps even folders of files. Then, as part of the lecture presentation one opens web browser pages, graphics using a file viewer, sections of spread sheets, etc. etc. Incorporating a window with Google Earth, especially including a pre-programmed fly-over is a nice touch as well. So, you show a web page with a recent news report on some site, use Google Earth to fly from the site of the campus you are on to the location of the site, zoom in, discuss terrain and geographical context, then using the file viewer show a handful of photographs of the site, then open a spreadsheet page with some data, pull up a few graphs, and finally display a PDF file of a published report on that site for a detailed discussion.

Then, ideally, engage in a live Google Hangout with the site’s excavator and one or two other scientists who want to complain about the excavator’s findings for a steal cage death match showdown.

That method … the desktop based meta-presentation … would also be ideal for capture with ScreenFlow. And my head can be there in a box down in the corner being amazed at it all. Though it would probably be better to get someone else’s head.

ScreenFlow allows for quite a bit of editing of the captured screen activity, combining of different sessions, etc. And, I just discovered (but have not yet tested) ScreenFlow’s ability to use a Green Screen. So, not only can my talking head be down there in the corner talking, but I can make myself appear to be somewhere I’m not. A few hominids tooling around in the background, a fancy laboratory setting, the Library of Alexandria for my Carl Sagan imitation…. the possibilities are endless!

Have you used any sort of screen capture software to record lectures or other presentations? Are you familiar with ScreenFlow? Want to take my class and see how it goes?

The Great Transition: Triassic Life on Land

Let’s see … The Triassic is about here:


(You can also look it up in this PDF file supplied by the USGS.

It is situated between two major extinction events, and is especially interesting because it is during this period that modern day ecological systems and major animal groups took a recognizable form. The preceding Permian, if contrasted with modern day, would form a very stark contrast while the Triassic would be at least somewhat more recognizable.

But of course the Triassic was in many ways distinct, different, and fascinating. Dinosaurs arose during the Triassic. The Triassic is also famous for its enormously large insects. It was also the time of Pangaea, where most of the Earth’s land was concentrated instead of being more or less spread out as it is now. Mammals, or at least the progenitors of what we now know of as mammals, arose then as well.

The Triassic was hot compared to today, and dry. Lots of sandy, arid-land deposits visible today date from this period. The poles were temperate, and the middle regions of the one giant continent was probably … very continental (mainly, dry).

So, all this adds up to the simple fact that the Triassic was a very interesting time period, and I assume that you would like to know a lot more about it. That would be where the new book, Triassic Life on Land: The Great Transition, comes in. This new volume in a series on “Critical Moments and Perspectives in Earth History and Paleobiology” (of which there are several other interesting must-have installments) comes in.

Sues and Fraser’s accessibly priced volume is neither a popularization of palaeontology nor a monotonous monograph of esoterica. It is a scholarly but readable detailed yet succinct description of this incredibly interesting time period. This is the kind of book that you will sit down to relax with, but do so with a pack of post-it notes handy just in case you need to mark something. Triassic Life .. is sufficiently detailed and well documented (excellent references and index) to be used as a textbook in a middle level palaeontology course, and sufficiently engaging for you to use as a source book for your next cocktail party.

The authors are widely recognized and respected experts in their field. The publisher did an excellent job with the book, which is very heavily illustrated and well laid out. Yet, most of the illustration are very nicely done line drawings and black and white photos, which keeps the price of this volume down despite the nice paper and excellent binding.

The book has eleven chapters, seven of which serve as mini-monographs of specific Triassic sub periods in specific geographical locations (such as “Late Middle and Late Triassic of Gondwana” and “Late Triassic of the Western United States”). Each of these chapters gives the basic information on where, when, and what for that particular subset of paleontological phenomena. Chapter 9, “Two Extraordinary Windows into Triassic Life” focus on two cases of Konzentrat-Lagerstätten (places of especially good preservation or richness): Solite Quarry in the eastern US and Madygen in Central Asia. Triassic insects. Very nice.

Chapter 10 is an overview of the large scale pattern of biological change during the period, and Chapter 11 examines the Triassic end-times, exploring the possibility of an end-Triassic impact, and other issues.

If you have an evolution-oriented relative or friend who’s birthday is coming up, now’s your chance: The book is new enough and specialized enough that there is no way they’d have it already. And, it looks enough like a coffee table book that others looking on will see it as a great gift even if it is a bit over the top in geek points.

Greenhouse of the Dinosaurs

You all know Don Prothero. He is an active member of the Skeptics and Science Blogging community. He is the author of several books, one of which you are totally supposed to own and if you don’t it’s kinda lame: Evolution: What the Fossils Say and Why It Matters. It occurred to me today that I never produced a formal review of one of Don’s other books that I really enjoyed: Greenhouse of the Dinosaurs: Evolution, Extinction, and the Future of Our Planet. The reason for my skipping that review is that I had a radio interview with Don during which we discussed the topic as some length.

Despite the fact that the word “Dinosaurs” occurs in the title, this book is only partly about dinosaurs. In fact, I would say it is mostly about mammals, insofar as the critters go. And that’s good because Donald Prothero is probably the world’s leading expert on Fossil Mammals. The dinosaur part is major and interesting, though. One of the mysteries Don addresses is the presence of Dinosaurs in the region of the earth that is dark for 6 months out of the year and generally frozen. Indeed, the “greenhouse effect” was very much stronger (in that there were more greenhouse gasses) in those days than today. All that atmospheric Carbon (in the form of CO2) was eventually to be trapped in the lithosphere, which helped cause the planet to cool to the levels that were around when we, as a species (genus, really) evolved. The world in which everything alive today evolved in is a world with a few hundred parts per million of CO2 in the atmosphere, the world of the “Dino Greenhouse” had much more CO2, and we are quickly heading back to the Dinosaur era level, which is going to really mess us up.

Greenhouse of the Dinosaurs: Evolution, Extinction, and the Future of Our Planet addresses questions of “Yeah, so, it was hot then and everything was fine, so Global Warming is not important.” Don also regales the reader with stories about doing palaeontology, about controversies in the field, and that sort of thing. And, he brings us past the K-T boundary, to the “Cainozoic” (age of “Cain) during which the earth cooled, and mammals took over to be the dominant large visible above ground life form. (Yes, yes, I know, bacteria are the dominant life form, yadda yadda… just don’t look for any murals of bacteria interacting on the wall of the Yale Peabody Musuem any time soon.)

Greenhouse of the Dinosaurs: Evolution, Extinction, and the Future of Our Planetis a great book. Highly recommended by me.

New CDCOTW Video on Sandy and Superstorms

Climate Denial Crock of the Week gives us this new video. Details here.

We are not yet where we need to be with this “when did you stop beating your wife” question sometimes in the form of:

“Can you REALLY attribute ANY storm to Global Warming, really? No? Then is global warming really real? Really?”)

Next time someone says something like that to you, consider answering the question with a question:

“Which major storm of the last two decades or so did not include any of the extra climatic energy provided to this planet by the release of fossil Carbon and other greenhouse gasses into the atmosphere by human activities? WHICH ONES, DAMMIT!?!??

That last bit is very important.

National Geo's Birding Essentials

Are you interested in birding but don’t really know much about it? Did you just put a feeder outside and noticed that birds are interesting, or did you finally get around to stopping at that wildlife refuge you drive by every week on the way to the casino and realize that walking down to the swamp to look at birds and stuff is both better exercise and cheaper than playing slot machines for nine hours straight? Or have you been birding in a casual way for a while, using your Uncle Ned’s old binoculars and a tattered and torn Peterson you found on the sale table at the library, and want to find out which aspects of birding you are missing out on? Filling in the blank spots in your knowledge of birding is easy given how willing birders and writers about birding are to tell everybody else about birding, and it is probably even easier to do with a book like “National Geographic Birding Essentials.”

(Full disclosure, I write for National Geographic’s Science Blogs, sure, but really, I have nothing to do with this book. I didn’t even get it as review copy, someone gave it to me for Christmas last year.)

As you know, in the beginning of almost every bird guide is a chapter (or two) on how to do the whole birding thing, some more extensive and some less extensive. The most extensive and useful for the novice that I know of is the front matter in The Young Birder’s Guide, which I highly recommend for middle school or so aged potential birders. Well, Birding Essentials is like that first chapter but in the form of a whole book. Here’s what you need to do to see if you should get a copy of this book and spend a few hours with it. Look at the following list of topics and see if you feel like you know enough about most of them, or not:

<li>Binoculars, how to chose one and how to use them.</li>

<li>Field guide basics, how to use them, etc.</li>

<li>Understanding status and distribution of a bird species</li>

<li>Details and terminology of migration, nesting, and other patterns of movement and migration

Parts of the bird. Here’s a short list of parts. If you don’t know them, you don’t really know the parts:

  • lores
  • eye line
  • supercilium
  • lesser and greater coverts
  • tertials
<li>Colors and patterns.  Bird color terms are atypical.</li>

<li>Methods of identification using field marks</li>

<li>Variation in bird features (sexual dimorphism included)</li>

There’s more, including strategies for approaching the field adventure that is birding, and dealing with rare variants, and so on.

Excellent birdy bedside reading, but mainly for the novice birder. If you work with bird watching in a science classroom, this is probably a good volume to have handy; tell your librarian to get it.
