Global warming effects? Ask a birder

Male Purple Finch.
While humans dither over global warming, many American bird species are making their move. The National Audubon Society has looked over the past century of Christmas Bird Count records. And it is clear that hundreds of bird species are wintering further and further north. The champion mover seems to be the Purple Finch, now found over four hundred miles north of its wintering grounds four decades ago. The Wild Turkey has also moved four hundred miles north. Along the Pacific Coast the Marbled Murrelet is abandoning the southern portion of its range and moving northward as well.
Some birds are not as adaptable and may face diminished range and even extinction as global warming continues.
Here in Southern Oregon we're now seeing Tree Swallows in the dead of winter. Some breeding birds have moved north from California and are here year round: Red-shouldered Hawk, White-tailed Kite, Mockingbird.

Backward interpretation?
So more of the globe is getting cooler?
No backward interpretation needed...
Not Backwards
the article?), but stated in other articles is that the birds spend their
summer somewhere north. In the winter they fly the minimum distance
necessary to find a habitat that isn't too cold and has food. What the
study believes is happening is that the birds are now able to stay warm
enough, and find enough food, in habitats that were previously too cold
for them. Being too cold also affects the food supply if the ground is
frozen over and/or snow covered.
Part of the logic is that the birds will expend the least amount of energy
possible to get to a wintering ground.
While there maybe typos in the story
broken
and poorly
formatted smart arse
response.
Maybe if you stop putting hard line breaks in and start using just the return key you could format your sentences and paragraphs to flow. That would make reading your reply so much easier. ]:)
Looks fine to me
confused. I see a properly formatted paragraph of several sentences,
followed by a single line break, followed by a single sentence paragraph.
I wish I cold send you a picture. So, humbly, I suggest YMMV.
I also don't see any "smart arse" response. He was clarifying missing
information in the original article. As for typos, my quick reading
identifies 6 typos in 9 sentences. Even for ZDNet standards, that's a little
high.
Hope you don't count this as a smart arse response.
No not
One thing I have noticed is that it's never a Linux Users post that is malformed. But a Windows users... Imagine that... ]:)
Not a Windows user..... try again. (NT)
Follow up to above
users - then the problem is not with the other users but the forum
software itself? Just asking you know.... with perhaps a hint of smart
arse-ness.
