- PepeGSay, on 09/17/2009, -0/+13If that's true then why didn't these birds migrate anyway? If they learn it from their DNA then they would migrate regardless of temperature and would never learn to not migrate. Clearly the birds are capable of adjusting more quickly than on a multi decade or evolutionary scale.
If it's cold, they migrate. If it's warmer they don't. Why would any animal expend all that energy to fly somewhere they don't need to? I would give nature a bit more credit. - partrow, on 09/17/2009, -3/+12They have been skipping their migration for a number of years.
Why?
Do you think the fact that they have found cities who welcome them to eat and poop year around on their golf courses and other landscaped areas might be the factor that keeps them from migrating?
They have simply found an easier way to live, without the long flight.
And I believe they are called Canada Geese, not Arctic Geese. - Propethic, on 09/17/2009, -0/+7Oh don't get me wrong I fully believe that, but I also believe that you cannot attribute poorly understood phenomena to other not fully understood phenomena every time it happens
- S3Plan, on 09/17/2009, -6/+11If memories are transfered through DNA, and that they don't migrate for many more decades or longer. The newer generations will probably not know to migrate when it gets cold and they will die when the Earth's temperature hits the colder times again. Thus, extinction!
I'm not promoting global warming one way or another. - dazparkour, on 09/17/2009, -2/+7Maybe they just don't want to get swine-bird flu.
- roodammy44, on 09/17/2009, -0/+4The planet might be fine, but that's only because it's a ball of molten rock.
Humans might wipe themselves out due to the control over the environment we now have.
We really need to spread to another ball of rock in case we ***** up this one. - Gndoab, on 09/17/2009, -4/+8the earth may be warming, or it may not be. I know for a fact, that even if it is warming as scientists say it is, it is no where near as warm in alaska (and canada) in the winter as it is in mexico. definitely not warm enough for species that normally migrate to stay and live through. there is another (as someone said earlier, maybe human cities? otherwise, I don't know) reason that they stay
Ketchikan had a mean monthly temperature of 31.9 degrees Fahrenheit, which is 4.4 degrees cooler than normal for February

vs. nearly 15 degrees C in mexico
http://www.climatetemp.info/mexico/
15 degrees C 59 degrees F.
so in other words, they went from being able to live in 60 degree weather to 30 degree weather. yeah. right - jebsilver, on 09/17/2009, -7/+10Guys, the earth isn't warming. I know this for a fact. I have my head planted firmly in the sand, and I can tell you it is very temperate in here.
- cornfeed, on 09/17/2009, -0/+3Not debating climate change one way or the other. But it is much less about temperatures than about food availability for geese. The geese can handle a lot of cold. As long as they have enough food to eat. Now this may require less snow cover to leave food more accessible to them. Or some outside agency needs to make food available, intentionally or accidentally, them, like humans. There are many northern Cities that have been feeding geese over the years. They now have large populations of year-round geese that stay as long as they get fed. Stop feeding them and they leave. An example--- Rochester Minnesota.
So DNA, less about temperatures, more about food. - VanRude, on 09/17/2009, -2/+5That's how evolution works.
Those that are too dumb to get out of harms way -> unfit.
Those capable of recognizing cold here, warm there -> fit. - Paranor01, on 09/17/2009, -2/+5Just don't deny that man, on a whole, has made changes to the biosphere that are not positive and have contributed to changes within it.
- 07dcolem, on 09/17/2009, -0/+3buried for using facts
/s - 07dcolem, on 09/17/2009, -0/+2@tao52nyc: Here they go again burying facts and opposing opinions.
- Mujokan, on 09/17/2009, -0/+2As usual not many read the article. It doesn't have to get to Mexico temperatures, it's just that now they can get at the eel grass in the winter. So they don't have to go to Mexico to find it.
- stephhicks68, on 09/17/2009, -0/+2Ahhhh- and they will forfeit all those frequent flier miles!
- pixxeldust, on 09/21/2009, -0/+1Yes it has. Yes it is, *****.
Go buy a prius, tool. - johndavidjack, on 09/17/2009, -2/+3The planet's going to be fine, long after we're gone. Don't worry about it too much.
- e2superman, on 09/17/2009, -0/+1Sounds like a good deal for the Geese. In Sunny Mexico they become dinner.
- claymoredeth, on 09/17/2009, -0/+1See, global warming isn't all bad. Those geese don't have to expend all that energy flying anymore. They can just live the life of luxury in one place and sit on their ass and get fat like the rest of us now.
- jadedsunrise, on 09/17/2009, -0/+1Guess that's one goose who isn't cooked.
- haterofps3, on 09/17/2009, -0/+1Maybe thats why the CND geese were flying the wrong way... All my life I have only really noticed them flying south, but the other day I swear I watched several flocks flying north. Really very strange
- tao52nyc, on 09/17/2009, -1/+2Real science? On Digg, that's crazy talk!
- yoderizer, on 09/17/2009, -0/+1There is a large contingent of Canada geese that decided there was no reason to leave east TN anymore. Now we get twix sized goose crap year round.
- cuervoman914, on 09/19/2009, -0/+1evolution, bitches!
- joot2112, on 09/17/2009, -0/+1... yet.
- poitsplace, on 09/17/2009, -4/+4Damn corporate fooled and/or funded denialist geese! They're trying to trick us all into believing that a warmer world is somehow capable of feeding more life than a barren sheet of ice and permafrost. Next thing you know someone will be trying to tell us that harvests have been going up for the entire warming period or that higher atmospheric CO2 makes plants more drought resistant by allowing them to get enough CO2 without leaving their stoma wide open.
- pinchduck, on 09/17/2009, -3/+3As the planet changes, animals adapt? Whodathunkit?!?!?
- rrwest, on 09/17/2009, -0/+0In "very cold" cities in Alberta, there are dozens of flocks of Canada geese and even mallards that never migrate south. In some areas of our cites, there are perfectly warm environments that allow them to winter over.
What I worry about is the fact that the Yukon had more than 30 days of abover 30 degree Celsius (around 60 to 70 degrees F) temperatures this summer. The average for the last twenty years or more has been less than 10 days, from what I understand. - Propethic, on 09/17/2009, -2/+2We need to find an arctic goose whisperer to make sure
- rrwest, on 09/17/2009, -0/+0More likely the extended length of warm temperatures enables the geese to stay north longer. The temperature doesn't have to rise by that extreme.
It also affects plants, which can then stay green for longer periods of time. Some species react to dropping temperatures before going dormant or turning colour in the fall. Others are affected more by the length of daylight.
Its all relative to species and their immediate environments. - DavidNiven, on 09/17/2009, -3/+3Buried for automatically assuming like an enviro-wacko that relatively few geese not migrating as normal means...
THE EARTH IS DYING DUE TO MAN-MADE GLOBAL WARMING!!!
Oh, no!!! Donate money quickly to the Goracle and his Church of Global Warming and Cow Flatulence before it's too late. Submit to the environmentalist lobby (which is making big money pushing their agenda, by the way). Listen to the leftists on Digg because they care and you suck. Pay attention to all the enviro-wacko websites because we all know they would never lie or have an agenda!!!
Pay no attention to the fact that most of the data points for measuring global temperature show a DECLINE in average temperature. - Propethic, on 09/17/2009, -2/+2You're under the false assumption that animals are living creatures, with brains and senses of their own
/s - Mujokan, on 09/17/2009, -4/+4No, it hasn't. No, it isn't.
- compulsive1, on 09/17/2009, -3/+2"Corporate fooled denialists invading this thread in 3...2...1....."
This comment brought to you by International Carbon Credit Traders Association. - rrwest, on 09/17/2009, -1/+0Data, like any other statistics can and will be skewed to fit the agenda of the researcher.
I go by what I can see, hear and feel. And by what my memory tells me.
The local Canada geese have not yet begun their migration south from our part of Alberta, the trees still have green leaves and it looks like there will be record temperatures for at least the next week, in the mid to high 20s (mid to high 60s Farenheit).
Only 14 years ago at this time of year, the birds had all migrated south, the trees had lost their leaves and the temperature was often below 10 degrees (low 50s to mid 40s Farenheit). That winter was the worst winter for the area in over 50 years. - johndavidjack, on 09/17/2009, -3/+1No, they are type of snow goose, specifically Pacific brant.
But I say let them migrate earlier, more chances to ambush them with the 'ole 12 ga. - prakash1234, on 09/17/2009, -4/+2Discovery.com, treehugger.com same company doing the Green PR for western nations.
- chinaman1212, on 09/17/2009, -5/+3Wild animals are strong creatures. I think it would take more than a degree or two to change there minds. None of the geese leave the pond by my house. Winters here in Saint Louis can range from 32 F degrees to colder than zero. I think this is just a ***** story like most of them.
- pixxeldust, on 09/17/2009, -5/+3Over the last 50 years, the earth has cooled.... Global warming is *****.
- MerchantofPanic, on 09/17/2009, -7/+5For millions of years migration patterns of birds have probably changed according to circumstances - on this occasion though, its our fault.
/sarcasm - tao52nyc, on 09/17/2009, -5/+2The "20th century warming" ended in 1998. We have actually cooled a bit since then. Real science. Read a book by Ian Plimer - look it up on Amazon. Honest science. It's all about the sun, solar wind, cosmic rays, plate tectonics, and our passage through the galaxy.
- WoWii, on 09/17/2009, -5/+2You people really think the Earth has warmed up SO much that they dont even need to migrate? That would be like a 30 degree rise...
- Propethic, on 09/17/2009, -8/+5Keep blaming every change in the natural world on global warming, its really starting to make a difference *rolleyes emoticon*
- garyi113, on 09/17/2009, -4/+0One more reason (albeit small) for loving global warming. Hopefully NE Ohio will warm up this winter but I doubt it. If global warming exists how come it never comes here?
- johndavidjack, on 09/17/2009, -6/+1"Humans might wipe themselves out due to the control over the environment we now have."
How arrogant of you. Just tell me, what exactly do we have control over of in the environment? Yes, yes, global warming, and other feel good terms due to our pollution and industrialization. Let me tell you something, if the planet wants to exterminate us, it can, and probably will.
Nuclear holocaust? There will be life on the planet again, just not us. - novenator, on 09/17/2009, -13/+7Corporate fooled denialists invading this thread in 3...2...1.....
