Are birds getting bigger because of global climate change?
latimes.com ^ | Nov.7, 2011

Birds in central California are significantly larger than they were 25 to 40 years ago, and researchers believe it may be because they are bulking up in body weight to ride out severe storms related to global climate change.

Over the last 25 years, a robin, for example, has increased about an eighth of an inch in wing length and about 0.2 ounces in mass, according to a paper published online in Global Change Biology.

The findings fly in the face of assumptions based on an ecological benchmark known as Bergmann’s rule: Birds and mammals tend to be larger at higher latitudes, perhaps to conserve body heat. Under this reasoning, birds and mammals would get smaller as they adapted to rising global temperatures.

But they also suggest that explanations for the bigger birds are more complex, according to researcher Jill Demers, executive director of the San Francisco Bay Bird Observatory.

“The degree of physical change over a relatively short scale of time is remarkable and surprising,” Demers said. “Similar studies in Pennsylvania and Europe, for example, show that birds there have decreased in size over the past several decades.”

Overall, birds in central California have grown an average of 2% to 5% in body weight and wingspan, said Rae Goodman, who discovered the trend while working as a graduate student at San Francisco State University, analyzing data from thousands of birds caught and released each year near San Francisco Bay and the Point Reyes National Seashore.

More study is needed to determine whether these changes are good for central California birds and how they affect food chains, Goodman said.

Or they are eating the scraps of our food we leave out for them. Have you seen the pigeons in a McDonald’s parking lot scarfing down french fries. They look like winged Michael Moores.

I think it is because they are eating more meals at McDonalds and Burger King.

No, it’s because Californian’s are getting smaller.

Birds, mammals and fish get smaller with warmer climate trends and bigger with colder climate trends. The birds are getting bigger. They are adapting to a colder world. The warming alarmists refuse to see what it right in front of them. All the evidence is there, all you have to do is look. Unfortunately, when the data contradicts your religion, you keep your faith in man-made warming, socialism, utopian dreams, what have youj.

ROFL That’s pretty much the explanation. If winged animals can grow big due to glow bull warming, then the average moonbat got bigger too.

I think it’s time for Michelle to look into this. American birds are getting fatter and fatter. The federal government needs to start regulating bird feeders.

Now there’s a campaign for you, Michelle!

I’ve noticed the same thing. I saw some robins that had doubled or tripled in size and changed to nearly all black in color. They were attacking some road kill to bulk up for the global climate change.

"And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God; That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.

If the birds are getting bigger because of anticipated storms, there are bigger questions here than merely the climate.

This suggests that birds somehow can see the future and act to adapt to it. This has profound theological implications.

Predestination, fortunetelling, scrying- this could be hugh.

Climate related phenotypic plasticity is more accurately reflected in changes to the ratio between body volume and surface area - in cold climates reducing the surface area relative to body volume is a method of conserving energy.

Why do the media and snake oil scientists persist with the simplistic view that additional heat equals more storms? One of the central beliefs of GW is that the poles are warming faster than the equator. This means a lower DIFFERENTIAL in temperatures...and less severe weather. These alleged experts are instead equating the atmosphere to a boiling pot of water. Nobody who has taken an introductory weather class should buy into this garbage.

When the winter is going to be bad, we get more fruits on our trees and bushes. The animals fatten up for the winter that way. Nature takes care of them.
If the birds are getting bigger, they need the increase in size for something. It's not just body weight, it's also length. Why would birds need to get longer?
So many questions!

Generally when you see a change like that in a relatively short period of time is would indicate some sort of selection pressure, e.g. longer, heavier birds are able to more efficiently access resources which increases their reproductive success, and the longer, heavier trait is passed along to their offspring.

With restrictions on the older and more effective insecticides, insects who once were under control are now literally out of control.

Birds eat insects, fortunately, and with a greater food supply, they will grow in size. Also, because of 24 hour cable TV, they get less exercise, like many Americans.

Pretty soon we will be shooting these birds for food. A great food chain and cycle.

Bon appetit! I suggest Honey Molasses BBQ sauce.

Birds in central California are significantly larger than they were 25 to 40 years ago, and researchers believe it may be because they are bulking up in body weight to ride out severe storms related to global climate change.

Even the AGW true believers agree that there has been no statistically significant global warming since 1995.

“Similar studies in Pennsylvania and Europe, for example, show that birds there have decreased in size over the past several decades.”

So birds get larger because of global climate change, and they get smaller because of global climate change.

Same old Los Angeles Times.

Over the last 25 years, a robin, for example, has increased about an eighth of an inch in wing length and about 0.2 ounces in mass

Have they considered steroids in the water?

What about growth hormones from cattle trickling down the food chain? See? It really IS BS!

Maybe worms are getting larger, so only larger birds are able to deal with them.

According to Darwin, the adaptation [NOT ‘evolution’] comes in response to environmental changes, not in anticipation...unless there's thiotimoline in the water or food.

I looked up a pic.
Not the same bird. It didn’t have the black stripes on its head- just a patch of white feathers on its head.
It was with a group of house sparrows.

You know how Suzette is about her bird feeder.
These crows start showing up out of nowhere.
She’s all over my back to get rid of’em.
“The crows are too big for the bird feeder,” she says.

That’s why I got the gun. I’m gonna pop a few.

This might be the case. With more food available to them during what used to be the lean months of winter, wild birds now eat better than their ancestors. It is the same reason that we are larger than our ancestors.

I would think birds would get smaller with increasing temperatures because warmer air is less dense than colder air thus and flying in less dense air would be more energy intensive.
