Songbirds in the US are getting smaller, and climate change is suspected as the cause.
A study of almost half a million birds, belonging to over 100 species, shows that many are gradually becoming lighter and growing shorter wings. This shrinkage has occurred within just half a century in response to warmer temperatures, and at this rate, many may disappear by 2035.
In biology, there is a general rule of thumb that animals tend to become smaller in warmer climates: an idea known as Bergmans Rule. Usually this trend can be seen among animal species that live over a range of latitude or altitude, with individuals living at more northern latitudes or higher up cooler mountains being slightly larger than those below. But global warming has thrown this process into overdrive, and many of the birds in North America will soon become so small, they will literally wink out of existence.
A black-capped chickadee is half as large as it cousins of thirty years ago The WWF funded study examined the weight and size of 48 individual birds that had been caught and measured at the ringing station from 1961 to 2007. What the scientists found was striking. The birds in North America are getting small. Lead Ornithologist Steve Martin was laughed at when he first proposed his thesis, but his critics are laughing no more.
The differences in size are stunning.
On average, the decline in mass of spring migrants over the 46 year study was 50%. Thats shocking as a young boy changing shoe sizes in reverse says Doc Martin. The rose-breasted grosbeak has declined in mass by about 40%, while the Kentucky warbler has dropped 30.3% in weight and the scarlet tanager 20.3%.
The trend is particularly noticeable among those birds that have bright colors.
In one obvious sense, the consequences are positive, says Dr Rajendra Pachauri, head of the IPCC. Now people will have to take global warming and the IPCC more serious, or else we will lose the ability to buy downy blankets or goose feather pillows.
Luckily, India has few birds, and this problem is not seen in the bird populations in my country, so we in India will not have to cut our greenhouse gas emissions he added.
Dr. Martin laments When we take pictures, we ask you to watch the birdie. Future generations will have no idea what that means and will think youre cuckcoo. Its really tragic.
They’ve all gone low carb
Right, which is why most of the worlds largest land based animals all live in.....sub Sahara Africa.
Do these clowns even bother to think before they publish this utter BS?
There are some people who actually believe this. :(
Someone should tell that to the African elephant!
The writer at Altered News has been practicing altered states.
If it can’t be expressed in figures, it is not science; it is opinion.
Now I know........
Look, I love birds, actually, but there are hundreds of thousands more killed by cats --- and tens of thousands more killed by windmills, for gaia's sake --- than those affected by (cough) global (cough) warming.
Giraffes, Rhinos, and Hippos asked to be on the memo list, too.
If the new crop of sparrows in the neighborhood is any indicator I suspect this may be all wrong. The little beggers are as bad as rabits!
Yes, well... There’s a funny story related by Kjell Aukrust, Norwegian writer, abut his brother Odd Aukrust who grew up to be the nation’s leading statistician. Using charts, statistical method and deep historical digging he proved, without a shadow of a doubt, that at the time of the battle of Stiklestad not one of the combatants could be seen above the grass and that the only thing that could be seen was a few arrows (small ones) making it over the grasstops.
I see science is still on the same track, only reversed.
Oops......should be rabbits!
You mean birds are not really shrinking? Does the president know about this?
Caption: “They don’t make ‘em like they used to...*urp*”
You didn’t know that Dinosaurs thrived in an icy climate? LOL! These clowns are relentless in their complete idiocy and they want everyone to know it. They are Cliff Claven on steroids.
Is this sattire? I know nothing about birds or science but this article is wrought with bs,
Thanks for a good laugh. The site is hilarious, especially the rendition of “The Homicidal Squirrel.” Beware: squirrels are developing a taste for human flesh due to global warming!
Dig your car out from this bad boy.
What? I thought COLD weather caused shrinkage.
The trouble with projections is the assumption that a trend (i.e. birds becoming smaller) is going to continue on the same trajectory. Very often, things don’t.
More science sacrifices at the alter of environmentalism in the church of political correctness. Like Obama, they seem oblivious to the damage to their own credibility.
That’s the sumbitch that pooped on my clean car the other day. I’m renting an antiaircraft cannon.
The rule applies to species. Whitetail deer are much smaller in their southern ranges than the northern. Reason: ability to retain heat. Volume increases as a cube...taller, wider animals increase volume relative to surface area...don’t radiate as much heat.
Ok every one at once “ Where have all the birdies gone here in 2010? Where have all the birdies gone? Playing and singing in he summer wind!” Ok hippy tune off!
The GW idiots are grasping at straws now.
Climate change causes global shrinkage??
“I like the red ones the best”
“Right, which is why most of the worlds largest land based animals all live in.....sub Sahara Africa.”
Yes, but the elephants that live in Canada are larger than those that live in sub Sahara Africa..
LOL, great point man, sheeze ....
"How can they tell you're small?"
"They give you a test -- it's a balloon -- if you can get inside -- they know -- you're small --"
"OK, kids, we're movin' now ... We're having some fun -- here at the fabulous Boarding House ..."
Will man, down in the Amazon, shrink into nothing, while his counterpart man, up at the North Pole, will grow the size of the Jolly Green Giant?
Jeeze these people who come up with these theories do not think past their short noses.
It's your own damn fault for washing your car. Birds never poop on a dirty car.
“Right, which is why most of the worlds largest land based animals all live in.....sub Sahara Africa.
Yes, but the elephants that live in Canada are larger than those that live in sub Sahara Africa..”
I was going to make the same point- polar bears in Africa tend to be smaller.
Yeah, that explains the elephants in Africa, and the emu in Australia.
Ever notice how, after getting out of a cold pool, you can't find...it?
Wasn’t there a web site somewhere that attempted to archive all the things purported to be caused by GW?
Is that Rodan?
The pool water was warm I tell you...warm!!!...hot even!!!
