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.
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!
hooray now if you had only logged in we would know who to congratulate.
Also eggs have been around much longer than chickens.
The birds aren't the only ones hurting with the warmest winter on record people haven't needed to buy nearly as much gas and electric to heat their homes this year.
Minimum threshold fixed. Thanks!
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.
In my neck of the woods (actually desert) it was over 90 degrees and the rattlesnakes are coming out of hibernation early
I wonder if their eggs are hatching early also
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.
I am Bernie Sanders, and I will levy a new multi-billion dollar tax against the poultry industry to alleviate this situation.
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.
I am the Pope and I'm here to let you know that prevaricating on Global Warming is not very Christian
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.

But, I'm too milquetoast to draw attention to myself.
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.
Please clap. And buy some guac bowls.
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?

AND more importantly.

This implies a lot of -- well you do the math
"temperatures less than or equal to 30 C producing all females, greater than or equal to 34 C yielding all males."
That is a lot of bull crock...

We play the game with the bravery of being out of range
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.
Imagine that, a change that effects the entire planet's atmosphere might cause a whole variety of changes across said planet. Its almost like if you change variables in a chaotic system you can get a wide range of surprising effects.
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.
But not bird fetuses, which is what really matters.
You are welcome on my lawn.

Would you please stop exhaling all that CO2?! You're killing me. You're literally killing the planet.
Just stop breathing! You filthy polluter.
Kinda
They have eggs, which are incubated and hatched internally
I did say hatch, never mentioned the eggs being laid
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.
That list has a duplicated item. This is clear proof that the whole list has been fabricated by a conspiracy of neocons to drive their global agenda! I demand to see the emails of the authors!

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.
No, this is God. Disregard that other guy, it's Lucifer. Anyway, just saying that I'm not doing it, you all are doing it to yourselves. I said I wouldn't flood the earth again, I didn't say I'd stop you from fucking it up yourselves.
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.
Rattlesnakes are ovoviviparous. They don't lay eggs.
Do you think AC will even know what that means?
The shepherds did so well protecting the flock that the sheep no longer believed that wolves existed.
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
Screw birds, my kitteh already changed to summer fur after all the warm days... then it snowed today.
The creatures outside looked from Alt-Right to Antifa; but already it was impossible to say which was which.
How the ever-loving fuck did this get modded +4 Informative?!?
Slashdot has been looking so much more positive lately (thanks whipslash) but the mods on this topic, WTF?
Another tech site (like El Reg) where a science topic can't be discussed rationally due to the denialist BS.
It's a fucking shame. Truly shameful that technologists let their personal tribal biases and politics get in the way of real, actual science.

Not only knows what it means, but, like all of us, except you, knows that ovoviviparous animals don't have placentas, but develop eggs with yolks that hatch internally, like he said.
Idiot.
They shouldn't believe the global warming hype
This perpetual motion machine Lisa made is a joke, it just keeps getting faster and faster. - Homer
yeah.. pretty cool huh. The shifting of ice mass and rising oceans changing the axis of rotation and spin speed ever so slightly. It's all happened before so it's not a big deal(?)... just neat to predict and measure.
Is the earthquake stuff pretty minor as well? We get more from fracking than our contribution to climate change?
By the time they return from their winter habitats, the local birds have finished breeding.
As the earth gets warmer, it is likely that long lists of items will have errors in them.
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.

Oh, so you looked at Wikipedia after being bitch slapped, eh?

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.
