The Heat Is On: Climate Change Causes Birds To Hatch Early (australiangeographic.com.au)
grrlscientist writes: A recently published study reveals that climate change can cause birds' eggs to hatch early. In addition to creating warmer temperatures that trigger early embryonic development in birds, climate change also increases the frequency and duration of heat waves. Thus, warming temperatures are leading to asynchronous hatching of individual eggs within a clutch and increased chick mortality, particularly for birds breeding in the tropics and semi-tropics, and in tropical deserts.
First post!
Wrong. It was freezing here yesterday and it was warm last week.
I am Donald Trump, and I endorse this message.
Confucius say, "Find worm in apple - bad. Find half a worm - worse."
Does this cause developmental issues, or does the heat also result in a faster maturation cycle while in the egg?
In this case, it seems they're equally developed, but latter lays don't hatch at the same time as the others and thus are less developed than their earlier-hatching siblings.
Now we know what happened to them! Pre-mature hatching gets u every time!
Flowers blooming early, too. My daffodils came up in mid January, a full two months early this year.
If the birds that hatch too early have a higher mortality rate they should evolve out of the species. Birds have a short life cycle so it shouldn't take that long.
since they hate birds. Even their criminal they had on the SCOTUS loved to kill them. Loved to kill them. He died while killing birds. While killing birds.

I read another study about a year ago (the link for which I can't find, so I profusely apologize in advance for the lack of citation), which also found that warmer temperatures were causing eggs to hatch sooner... but that the new birdlings were starving to death for a different reason: the timing of their hatching no longer aligns with the bloom of insects which are required for their sustenance. Apparently the insects did not get the memo that the warmer temperatures should also make them spring forth earlier in the season. So they are still business as usual after the young birds are already dying out, but as far as the birds are concerned, the bugs are late to the party... now I wonder if an additional side effect is an atypically larger insect population due to the comparative lack of predators.
Premature egghatchulation
It happens. Even to Zebra finches.
NEWS FLASH: The world has never been static.
If you want news from today, you have to come back tomorrow.
I agree that climate change is causing longer heat waves and impacting wildlife in many ways. I don't think that's in doubt. Climate change has had dramatic impacts on animal and plant life during most of the history of the Earth. It's led to mass extinctions, migrations, and dramatic changes in habitats. In the distant past, the Earth was almost certainly entirely glaciated, what's called the Snowball Earth Hypothesis. At other times, the Earth has been significantly warmer than it is today, resulting very small if any polar ice caps. There's plenty of evidence for this and it's pretty much universally accepted.
Yes, there is a lot of variability in carbon dioxide and other greenhouse gases during the history of the Earth. In prehistoric times, carbon dioxide levels were many times higher than they are today, though the Earth wasn't really that much warmer. The reason for this was the sun being several percent dimmer, cancelling out some of the warming caused by greenhouse gases. There's also evidence in more recent, but still prehistoric times, that the carbon dioxide variations actually lag slightly behind the warming and cooling cycles. Carbon dioxide in the atmosphere is very much regulated by the oceans, which have the potential to absorb and release it under certain conditions. The oceans are a massive reservoir of carbon dioxide.
The takeaway point from all of this? Geological evidence indicates that changes in the sun and the oceans are the primary drivers of climate change on Earth. We are at most a very small part of the climate change currently going on. Climate change has always been driven mostly by natural changes in the sun and in the oceans. The present day is no different. Just because humans are on the Earth now doesn't mean that the sun and oceans have suddenly ceased their roles to allow us to take over. This climate change is caused almost entirely by the sun and the oceans.
Native communities in Northern Saskatchewan are dealing with the problem of caribou herds moving north. Their ranges are no longer within range of hunters from the communities. I theory, the climate change would have probably cause buffalo to move north to replace them, but the buffalo are mostly extinct, now.
Sometimes boldness is in fashion. Sometimes only the brave will be bold.
How long, how far will have to progress, and how much damage will have to occur before bull-headed ignorant people actually have to get their heads out of their asses and admit that global warming is a Real Thing? Knowing how stupid the average Human can be it'll be exactly Too Late to do anything about it. My only solace is taken in the fact that I won't live long enough to see the world and everything about it I like destroyed by Global Warmings' effects.
We must immediately divert all resources from the war on drugs, and wage war on carbon. Cook a steak on the grill? Go to jail. It really is that simple. /sarc.
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?
Those chugs are buying groceries at Safeway's. They don't hunt shit! Who do they think they're kidding?
The end is nigh!!!!!!
SJW's don't eliminate discrimination. They just expropriate it for themselves.
My friend Junior says,
"Fewer birds, means more available shotgun shells and less poop on windshield."
The increase in mortality is a temporary result of warming. Eventually those that hatch earlier will dominate through natural selection. Then the faster rate of birth that follows will offset all the other problems we have been causing and birds will come to dominate the Earth. I look forward to welcoming our new feathered overlords.
i did not submit that link. my headline and my words were stolen and the original link to the story i submitted -- http://www.forbes.com/sites/gr... -- was replaced with the australian geographic link. honestly, the australian geographic story pales compared to the story that i shared.
Would you please stop exhaling all that CO2?! You're killing me. You're literally killing the planet.
Just stop breathing! You filthy polluter.
Confirmation Bias
In psychology and cognitive science, confirmation bias (or confirmatory bias) is a tendency to search for or interpret information in a way that confirms one's preconceptions, leading to statistical errors.
Did these "Researchers" rule out all other possibilities? Or did that just look and say, "this fits"?
Because then you can say Correlation does not mean Causation.
Odds are, they had a suspicion and went looking for evidence that confirmed their suspicion. But unless they ruled out all the other reasonably possible causes, then all they have is a correlation. Did they work with ornithologists? Vets?
This is what happens when Government Grant money flows freely to people that toe the party line...Sloppy Science.
I can get my chicken filet sandwich that much sooner!
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
So birds in their wisdom can adapt to climate change but the weeping willies say humans can't.
Actually, Justices Kagan and Scalia were hunting buddies... really...
You liberals just don't understand that all of Washington is the same. You seem so desperate to hate on Republicans, but every attribute you come up with actually applies to both parties.
this is just one species covered in the study. this study is very limited to location. i don't see any global correlation to any other species are geographic area. very poor study. I am not sure if this would even qualify as real hard science. more like a backyard bird watchers experiment.
Is this a good thing or a bad thing? Would that result in an overpopulation of birds, and further global warming, and hatching even earlier, until birds stop laying eggs and reproduce like humans - birds coming directly out of them rather than hatching from the eggs
They shouldn't believe the global warming hype

By the time they return from their winter habitats, the local birds have finished breeding.
In all of this planet's history we've seen more significant changes in the climate and at rates much greater and slower than what we've seen. The flora and fauna has adapted before and will adapt again.
The interesting thing about how climate, flora, and fauna interact is that a change in any one produces a change in the others. Climates do change, fauna and flora adapt, and a new climate is produced.
At one time I would have been upset about the potential extinction of a species but no more. I remember hearing over and over again on how many species die off due to climate change. All of that got erased in my mind when I heard how many new species developed in that time. It is quite possible that we are seeing the greatest biological diversity that has ever existed on Earth.
Species die off, that's life. In fact it is required for species to die off for new, more robust, species to take its place in the ecology.
I've also discovered on how the concept of a species is very fluid and not well defined. For the longest time I thought a species was defined as a population in that a pair of mates could produce offspring capable of reproducing with another mate from that population. Then I find out that not only are grizzly bears and polar bears closely related enough to produce viable offspring it is exceedingly difficult to distinguish between the two species in certain parts of the world. Grizzly and polar bears have a range that overlap. When it comes time to breed the bears don't care much about what color the fur is of their mate. The cubs will adopt the feeding habits of the mother. Brown bears are easy to find and kill in the snow, and white bears stick out in the forest. The color of the coat is largely based on the climate the bears are found, not the genetics of the population as a whole.
What do bears have to do with birds? If these birds die off because the climate is too warm for them then I expect that same species to develop habits and genetics to adapt. In a matter of years this problem will solve itself and the birds will live on.
This is only seen as a problem because some biologists are grabbing on the keywords of the day to get publicity and, no doubt, funding.
In short, move along, there's nothing to see here.
To those that think I'm heartless, bought out by the oil lobby, and/or whatever else that might be used to turn me into a sub-human I say this... bite me. This is basic biology at work. Had this happened in another time, in another place, this would not be headlines. It'd be turned into a graduate paper at best and filed in a university library where no one would ever read it again.

Anecdotal observations ...
In Southern Ontario where I live ... this year I have been hearing many song birds in early and mid February. Today (Feb 20), it was a male cardinal singing. A couple of weeks ago, it was Red Winged Black Birds, and American Goldfinches.
This is very unusual. It was not until March that we would hear them. I am not saying they are migratory, since some of them choose to stay and feed of bird feeders in people's backyards. But the act of males singing is the unusual part ...
It is an El Nino year though, and winter has been unusually mild.
2bits.com, Inc: Drupal, WordPress, and LAMP performance tuning.
The PDO is in its negative phase for about 12-15 years so half way through, the AMO has peaked and is on the way down for about 5 years now and the sun has peaked at the weakest level in centuries. Yes we just had a big el-nino but we had one of those in the middle of the 1945-1977 negative PDO as well.
So now it will get cold as la-nina hits and the 3 negative phases take hold. It will be a good test for the "CO2 is the control knob of climate" idea. We are still putting more CO2 out than ever before and our atmosphere levels are rising steadily. So if that idea is correct it should be able to overcome the natural cycles. If we drop 1 degree C or more over the next two decades while increasing atmospheric CO2 levels then the idea is wrong.

Well, looks like if birds are hatching early because they are warmer, then I guess evolution will take care of the issue of incubation and how birds do it. We are doomed.
