Global warming’s effect on bird migration profound, Audubon Society study says

Here in Kansas

A list of birds that are becoming more common and less common in Kansas, perhaps because of shifts related to climate change, and the estimated miles the birds have moved north over the last 40 years, according to the Audubon Society.

Less common species:

• Black-billed Magpie, 85.6• American Black Duck, 182.0• Rough-legged Hawk, 178.7• Black-capped Chickadee, 90.3• American Crow, 88.8

More common species:

• Snow Goose, 217.1• Hermit Thrush, 91.4• Wood Duck, 37.1• Marsh Wren, 25.2• Ring-necked Duck, 219.2

— An Audubon Society study to be released today found that more than half of 305 birds species in North America, a hodgepodge that includes robins, gulls, chickadees and owls, are spending the winter about 35 miles farther north than they did 40 years ago.

The purple finch was the biggest northward mover. Its wintering grounds are now more along the latitude of Milwaukee, Wis., instead of Springfield, Mo.

Bird ranges can expand and shift for many reasons, among them urban sprawl, deforestation and the supplemental diet provided by backyard feeders. But researchers say the only explanation for why so many birds over such a broad area are wintering in more northern locales is global warming.

Over the 40 years covered by the study, the average January temperature in the United States climbed by about 5 degrees Fahrenheit.

“This is as close as science at this scale gets to proof,” said Greg Butcher, the lead scientist on the study and the director of bird conservation at the Audubon Society. “It is not what each of these individual birds did. It is the wide diversity of birds that suggests it has something to do with temperature, rather than ecology.”

not warm enough to move the cuckoos from Lawrence.

jimincountry - your knowledge base, and that of all the non-believers - is why we are screwed. KS was covered by glaciers 3000 years ago??? Try 600,000 years ago (oh sorry, that goes against the KS belief that the earth is only 5000 years old) and the glacier only made it to the NE tip of KS.They are referring to the last 40 years because that was when they started studying the migratory patterns of these birds. And it's done in January because they are studying where they are staying in the winter.And gr - global warming means an overall average increase in temp across the GLOBE! Certain areas are having higher temps, us included. Some areas lower. See, there's this thing called meteorology and if you studied it, you'd learn that KS gets weirder weather because of the Rockies and the gulf flow. As the overall temp of the globe increases, weather patterns will get stranger and we'll have bigger storms, droughts in areas previously unaffected, etc....But you crazies just keep on believing it's all a myth. Enjoy these 70 degree temps in February and don't believe at all that what we're doing to this planet isn't affecting the weather. I'm sure god just decided that we deserved a warmer February than normal and thought it'd be cool to break a bunch of records.

I've noticed alot more Bluebirds hanging around this winter. O.K. with me.

And where were these same species habitating the 40 yers before that and the 40 years before that and the ...............so on and so on. Weren't there glaciers in Kansas a few thousand years ago?! Good gawd, who believes anything this bunch, the AP, decides to publish while they hide anything that isn't inline with liberal "the sky is falling" crap.

This is scary. We need to wake up NOW and do all you can to stop Global Warming. It appears that in forty years 35 miles north is a little under a mile a year. What happens in 100 years? How about exponentialism dropped into this mix? We had better take this more serious-Im glad we have a prez who will at least bring this sort of thing up in conversation. Lets move now on this whilst we can....

"Over the 40 years covered by the study, the average January temperature in the United States climbed by about 5 degrees Fahrenheit."Why January? Why not July? February? I thought the climate has only supposedly increased a fraction of a degree. Someone said it is happening too quickly and wildlife can't adapt. This article says it adapts quickly! Good news! And good news when it gets colder. Though, getting very much colder will do much more damage."Please ignore the warming of the Earth's core."Hal, could you give any evidence whatsoever, that the Earth's core is getting warmer?

Please ignore the warming of the Earth's core. It does not concern you. Carry on.

I thought it was "climate change" this week. Darn that Al! I wish he would make up his mind.
