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.
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!
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.
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.

This climate change is caused almost entirely by the sun and the oceans.
But this isn't borne out by evidence. The sun has cooled very slightly, but the temperature has spiked up: https://www.skepticalscience.c...
The oceans absorb and release carbon dioxide in direct proportion to atmospheric carbon dioxide. They essentially function to reduce the impact of atmospheric CO2 changes that would otherwise happen, in either direction. The ocean doesn't just burp out CO2 on a whim.
Every reputable expert on geologic evidence I can find suggest that geologic evidence actually indicates that current climate change is overwhelmingly from human activity, and unusually rapid. There will of course be error bars and overall trendlines from natural sources as well, although it's not even clear that trendline runs in the same direction as current climate change.
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"?
The end is nigh!!!!!!
SJW's don't eliminate discrimination. They just expropriate it for themselves.

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...

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.

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!
Why would anyone engrave "Elbereth"?
Good post, but you'll probably get modded down. Slashdotters can't stand reason. Most aren't scientists and have no clue as to how science actually works.
I can get my chicken filet sandwich that much sooner!
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
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.
Or you could go actually read the original paper to see if you could detect any confirmation bias. I did and it's not that hard to read if you have a little biology literacy.
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.

Well there's your problem. Getting your science information from Scientists, instead of Politicians and the industries that own them. Whooooeeeee! what next? Gettin' healthcare from Doctors? That's crazy thinkin'!

So birds in their wisdom can adapt to climate change but the weeping willies say humans can't.
Of course we can. Those adaptations might not be all that much fun for some of us though.

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.
The paper was about the effect of temperatures on the nesting success of zebra finches. As part of the study they looked at natural conditions but they also tested the effects of artificially raising the temperature. The paper barely mentions global warming.
here in the UK where we have hot and cold seasons like, spring is arriving a lot earlier than it used to and the spring plants are also growing earlier which may also screw the birds breeding cycles up as they'll have to match the food growing season

NEWS FLASH: That's not insight and we know that already.
NEWS FLASH: that doesn't mean CO2 isn't making the glob warm and the climate change.
SJW n. One who posts facts.
It's playing havoc with hedgehogs too, they come out of hibernation too early.

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.

Ignore both of them. They're just minors in the pantheon. The council vote is what counts and we voted long ago that you're essentially just a TV show.
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.

Rattlesnakes are ovoviviparous. They don't lay eggs.
Do you think AC will even know what that means?
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.
Oh, so you looked at Wikipedia after being bitch slapped, eh?
