So I put down my homework and decided to watch this little wonder creeping around the trees in my backyard. He seemed a little wary of me, but couldn't have cared too much since he landed in my backyard pond to take a drink. At this point, however, another bird appeared- entirely golden-yellow with red streaks on the chest. It was a Yellow Warbler, and it too, had come down to drink from the pond.Sunday, May 8, 2011

What's the Deal with Wolves???
First of all, it's hard to determine just HOW many elk the wolves are taking. Studies on this matter are few and far between, and without proper research, its nearly impossible to determine whether wolves should be held responsible for declines in deer and elk populations. According to studies by the International Wolf Center, a single wolf may consume between 14 and 19 deer-sized game animals per year. Multiply that by few thousand and it would seem like that's alot of kills, but in truth, this is NOTHING compared to the number of the deer and elk that starve, collide with vehicles, or are taken by hunters every year. By keeping deer and elk populations in check, wolves actually do alot of good by preventing them from overgrazing and outstripping their food supply.

Interpreting Nature
Monday, April 11, 2011
Update
- Aside from online consumer homework, a visit to Lawrence University, and a bit of birding here and there, I did relatively little over the course of spring break.
- I GOT ACCEPTED INTO CORNELL UNIVERSITY!!! (A place I'll be visiting on my own this week)
- While I was visiting Lawrence up in Appleton, I did some local birding and stumbled across YET ANOTHER BOHEMIAN WAXWING!!! Unlike last time however, the bird actually stayed put and provided my entire family with excellent looks.
- I just tested out my first homemade bird blind: a large cardboard box with 2 holes just big enough for a camera lens. Although the birds and animals don't seem to mind being followed and photographed by a man in a giant box, I'm pretty sure that I weirded out the neighbors.
- Last but not least- it looks like spring's finally coming here to stay! With Sunday's warm spell, all the plants are coming up, the grass is green once more, tree are budding, and the daffodils are in bloom!

A Weekend Escape- Part 2 (The Mound Builders!)
A Weekend Escape- Part 1
At Emiquon National Wildlife Refuge, a shallow, 2,000 acre lake formed at the junction of the Illinois and Spoon Rivers, snow geese often gather in the tens of thousands, accompanied by pelicans, bald eagles, and thousands of other ducks and waterbirds. Interestingly enough, this wildlife magnet hardly existed before the Nature Conservancy purchased it in the year 2000 (none of my old bird books on Illinois mention it). Although the area had historically been a giant wetland, years of intensive farming operations had all but drained the surrounding marshes and confined the the Illinois River to manmade channels. Only in recent years, when the Nature Conservancy removed the drain tiles, planted native flora, and restored the river to its original course, did the wildlife start to come back.
In one nearby Fish and Wildlife Area known as Banner Marsh (a place I would have liked to stop at, but didn't have time), the 4,363 acre property was initially a strip mining operation. This just goes to show you how quickly nature can heal.

The Last of the Bluefin Tuna
It’s been several hours since my last meal, and for some reason, I’m craving a big, juicy, tender filet of fish— preferably halibut or whitefish. Maybe trout? Mahi-mahi? No wait, I got it- A tuna burger! Mmmmmm so delicious.
It disturbs me that I think about these kinds of thing when I should be writing about the depletion of fish stocks, destruction of aquatic ecosystems, and ruthless, unregulated nature of our fishing industry. It certainly proves how strong our hunger instincts are. Sometimes I wonder: If I was stranded on an island with the last breeding pair of dodos, there was no help in sight, and there was nothing else to eat, would I have the will to refrain from eating them?
Anyways, that’s not my point. What I mean to say is that fish are in trouble. Now this is not true for every species, but for large predatory fish like tuna, grouper, and sharks, the situation is dire. Big fish are disappearing at a rate faster than anyone could have imagined. Bluefin Tuna- which are prized on the Japanese sushi market- have declined more than 90% since the 70’s, and are now listed as “critically endangered” by IUCN Red List. It’s really a shame too, because these are such majestic fish. A full-grown adult -bulging with muscle and power- can measure up to 10 feet, weigh more than 300 pounds, and reach speeds up to 50 mph. To think that such magnificent creatures would be slaughtered en masse and reduced to cat food seems pretty revolting to me.
Yet despite warnings of overfishing, Japan and a number of other countries continue to deplete fish populations- from the majestic tuna to rather gross-looking Patagonian Toothfish. With improved, industrial-scale fishing operations, virtually nothing is safe from exploitation. Even the deepest, blackest recesses of the ocean are fished to the extreme. Trawling nets are indiscriminately dragged across the seabed, killing all sorts of untargeted creatures as well as destroying seafloor ecosystems.
Some deep-sea fish like the Orange Roughy (a long-lived member of the Slimehead family) are already starting to suffer from this type of trawling, since they tend to be VERRRRYYYY slow to reproduce. Young roughies take 20-40 years to mature, and if you’ve ever had orange roughy, chances are good that you’re eating a 50-year old fish.
Although many countries now enact quotas on the allowable catch within their waters, a vast majority of fisheries are poorly regulated. With oceans spanning the globe, poaching is easy, and many countries (Japan in particular) tend to ignore limits imposed on fishing.
Although people nowadays may have higher eco-awareness, international cooperation may be better, and people may be finally waking up to the effects of overfishing, a tragedy of the commons seems to be playing itself out. According to a 2009 prediction, Bluefin Tuna may go extinct within 3 years. Unless people act now, we’ll simply deplete the large fish, move onto smaller ones, and repeat the cycle until there’s nothing left but plankton.<----- :(

What is "Clean" energy?
Indeed, humanity possesses both the knowledge and resources to combat climate change, slow it down, and reduce the disaster to something manageable. According to Jeffery Sachs (writer of Commonwealth: Economics for a Crowded Planet) we clearly have the brains and technology.
This said, I'd like to discuss what is meant by "clean" technology. More often than ever, you'll see the eco-friendly label on products. You'll see "green" options everywhere. Shade-grown coffee. Organic dish-soap. Biodegradable egg cartons. Energy-saving light bulbs. I think it's great- and for sure, the success of these products is wonderful, but one must still remember that we live in a consumer-based society. Businesses have and always will be motivated by profit, even if it comes at the expense of others. Now this is not to say that all energy companies are run by evil, selfish, money-hoarding capitalists- but in this day and age, one should always be aware of greenwashing schemes.
This brings us to the question: What's the cleanest source of energy we can afford? Pushing all business-related bias aside, you'd think the answer would be easy. It's not. Like Newton's first law of physics, every action of mankind has an opposite reaction, or in other words, a trade-off.
The drawbacks associated our use of oil and other fossil fuels is pretty clear, so I won't go into that too much.
Nuclear energy, despite being a relatively clean source of fuel, comes with a whole array of negative associations, such as Three-Mile Island, the Chernobyl Incident, and the possibility of all humans turning into flesh-eating zombie-mutants after exposure to radiation.
Hydroelectric energy has always presented environmental problems where building dams are concerned. Not only do dams disrupt the natural flow of rivers by flooding certain areas, but they also jeopardize the existence of certain fish and aquatic creatures by altering their habitat, separating populations, and preventing them from dispersing.
Even some of the most innocent-sounding, "eco-friendly" sources of energy have their trade-offs and drawbacks. According to the American Bird Conservancy, 10,000-40,000 birds die every year in the US from collisions with wind turbines. Although this is a small number compared to the millions that die yearly from window collisions, it's still important to consider when building wind farms along major migratory routes.
Solar energy is an amazing concept- I yearn for the day when every house and car has its own solar panels. Right now, however, it just so happens that our country's largest source of solar power comes from the Mojave Desert, whose fragile ecosystem will most certainly be imperiled by upcoming development for new solar projects. In fact, I was just reading a New York Times article about how solar energy companies in Southern California now face legal challenges based on environmental grounds.
So in any case, my point is this: As awesome as a new source of energy may sound, it's always best to study trade-offs before implementing it. Nuclear's fine, as long as it's well-contained. Wind farms are great, but not next to a bird sanctuary. You get the picture.

Native Plant Gardening
For the past two years, I've been transforming my yard into a native wildflower garden, and now that the snow is finally melting, it looks like I'll finally be able to resume gardening where I left off before winter.Monday, February 7, 2011
Was Shakespeare a Birder?
In any case, I've been using the extra time indoors to read up on Hamlet and some of William Shakespeare's other works.
Once you're able to see past some of Shakespeare's difficult language and seemingly undecipherable phrases, his writing is truly outstanding. Religious texts aside, Shakespeare's works may be some of the most influential literature of all time. Cultures from around the world have adapted versions of Shakespeare's plays. A suprising number of nuances that we use in our everyday language come from Shakespeare. The theme of "star-crossed lovers", which Shakespeare used for Romeo and Juliet, is now the basis of almost every romance novel or movie.
Aside from brilliant plot elements and universal themes, Shakespeare's plays are filled with clever metaphors, allusions, and "pop-culture references" for his time.
Among the various things Shakespeare refers to, birds definitely seem to be a favorite subject of his. Not only does he refer to the generic birds like "dove" or "eagle", but he actually mentions over 45 species throughout his works. Most are common British species, such as blackbirds, robins, skylarks, but among these, there are definitely some obscure ones.
-In King Lear, there's mention of Choughs and Jackdaws- which are both relatives of crows.
-Woodcocks are mentioned in a number of plays. These plump, supposedly delectable birds dwell on the forest floor, and due to their habit of freezing rather than flying from danger, they are particularly easy to catch. Indeed, I've seen woodcocks in the wild, and nearly ended up stepping on one almost every time. If you just look at a picture of one, they appear rather silly, with huge eyes, fat bodies, and an oversized beak.
-The "Night-Raven" that Shakespeare mentions in Much Ado About Nothing is actually a Bittern- a shy, nocturnal heron that is rarely glimpsed by people.
-Lapwings are a species of plover, whose young are usually able to get up and run around within minutes of hatching. Hence, Shakespeare writes "This lapwing runs away with a shell on its head" (Hamlet).
-The Wryneck, which is mentioned in the Merchant of Venice, is a particularly odd one. The bird itself is a rare, but generally widespread relative of woodpeckers. According to Wikipedia, its Latin name, Jinx torquilla, comes from the use of this bird in medieval witchcraft.
-Tercel, estridge, and staniel are actually falconry terms, which are used to describe falcons as we would use colt, foal, mare, or stallion to describe a horse.
-I particularly enjoy the birds known as wagtails, and nearly laughed out loud after reading "Spare my grey beard, you wagtail!" from King Lear.
-And of course, there's the European Cuckoo, which not only mocks married men with its call, but also lays eggs in the nests of other birds (forcing them to care for its monstrous, oversized young).
Although you may think these mentions of birds are nothing more than little flowery details, they contribute a great deal to Shakespeare's plots, and moreover, the modern world. In the late 1800's, a Shakespeare fanatic named Eugene Schieffelin decided to bring every bird mentioned by Shakespeare into New York City. After bringing finches, larks, and nightengales overseas and unsuccessfully trying to introduce them, Eugene released 60 European starlings into Central Park, thinking that they'd make great music and pest control. Unfortunately for us, starlings quickly spread across the continent, and now number in the hundreds of millions. Along with pigeons and house sparrows, they are considered an invasive species in North America, and have been shown to displace native cavity nesters such as woodpeckers and bluebirds.

Obama's State of the Union
So in any case, I thought this speech brought up some interesting discussion topics. First off- whether you're conservative, liberal, or moderate- you have to admit, Obama does a pretty damn good job of reaching out to both sides. As Sheryl Stolberg of the New York Times wrote, "There were no boos or a shout of 'You lie!' as in years past. Many Republicans and Democrats sat side-by-side-- the first time anyone here can remember such mixing". Indeed, Obama pushed for a number of bipartisan measures, including but not limited to clean energy policies.
There were several parts in Obama's clean energy spiel that I literally jumped up and applauded for, but overall, I'd have to say it was a little disappointing. Compared to his portion on education (which I believe was the strong point of his speech), Obama's talk on clean energy seemed to lack the same kind of depth. Instead of discussing strategies and providing specific examples like he did for other topics, Obama speaks rather vaguely about environmental policy. Whereas Obama devoted entire paragraphs to the importance of education (which, I kid you not, is just as important), he never mentions the reasons for developing clean energy. The term "climate change" does not appear even once in his speech.
Of course, you can't really blame Obama, especially when he's trying to reach out to Republican party. As we all know, climate change has become a dividing issue between democrats and republicans, not so much on the basis of whether it's real, but how much attention it deserves.
As I discussed this speech with teachers, classmates, and family, I came to realize it was perhaps Obama's best intention not to bring up a touchy subject like climate change. In a speech aimed at uniting Americans regardless of political stance, the mention of this subject would almost certainly be counter-productive. So, again, it's a dividing issue.
I just find it a shame how environmental policies, which should consist of simple, common sense, are so heavily politicized. As we're seeing already in Australia, Brazil, Pakistan, and various ecosystems across the world, the effects of climate change are real. It'll kill us. And while other countries are pulling themselves together to take preventative measures, the US- which is responsible for 20% of the world's carbon emissions- is too busy bickering and fighting over their own laws to do anything about it.
PS: Read Jon Choi's blog, where there's plenty more information on climate change and politics.
PPS: Just in case you were wondering, I'm a fairly moderate liberal on most issues. With the environment, I just tend to be a bit more extreme (As I like to say, I love birds and trees more than my own species).

The Making of the Fittest
For a book that is supposed to teach me everything I would otherwise learn from textbook chapters, I have to say this is a good read. In The Making of The Fittest, Sean Carroll describes all the intricate genetic processes, mathematics, and mutations behind evolution. It's really quite interesting. Carroll presents the facts to his readers with a simple, down-to-earth prose-- far removed from the scientific jargon that you might expect from this type of book. This makes the book fun, somewhat fast-paced, and fairly easy to comprehend. Some of the things I particularly like about Carroll's writing style is that he's willing to provide examples, make analogies, and delve into background information. When describing how Old World Monkeys and apes evolved color vision, he first describes what exactly makes color vision, the genes responsible for our vision, how color vision evolved in birds and fish but not mice, and goes on to explain how color vision may have disappeared in early mammals.
Even though I have yet to complete the book, Carroll has taught me some fascinating things. Until now, I never fully understood how organisms lost certain traits over time. According to Carroll, the phrase "use it or lose it" applies to genes. When a gene does not face pressure from natural selection, there is nothing stopping a mutant gene from reproducing and being passed on to offspring. Where I thought organisms evolved blindness or flightlessness simply because they didnt need eyes or wings, I now know it's because mutations are allowed to accumulate in certain genes of theirs.
I must say, Carroll's writing occaisionally goes over my head when he talks about base pairs or protein codes, but I believe that his writing beats alot of scientific works in terms of readibility.
RARE BIRD ALERT
In any case (despite the fact that there's school tommorow) I am REALLY excited. I participated in the Waukegan Christmas bird count yesterday and found an insanely rare bird.
This bird was a BOHEMIAN WAXWING- a nomadic, berry-loving creature from the Arctic. It is closely related to our familiar Cedar Waxwing and is similar in many ways. Both species have plump little bodies, short crests, brownish plumage, and waxy red blobs on several flight feathers (hence the name). They are very gregarious and will often travel in huge flocks in search of berries and small fruit. Because they occaisionally eat fermented berries, all waxwings have evolved strong, efficient livers- allowing them to recover quickly from drunkeness.
The Bohemian Waxwing is like the Cedar Waxwing in habits, but is slightly larger, grayer, and generally rarer. Unlike the Cedar Waxwing, which nests in parks and gardens across the US, Bohemians nest way up in the arctic and will wander unpredictably when food is scarce.
So in any case, I was counting cedar waxwings when I noticed one that didnt look quite right. Here's how it went:
Ari: Oh! Look! A waxwing flock.
Jason: Let's count them.
Ari: 1...2...3...4...5.....................28...29...30...31...what the?.......HOLY S#%&T!!!!! THERE'S A BOHEMIAN WAXWING!!!
Jason: Oh my God. You're right!!
Thinking it would stay for a few minutes, I ran back to the car to get my camera, but unfortunately, the whole flock was gone by then.
I still can't believe I saw that bird. Here's a photo, in case you were wondering what it looks like.
