Global Warming Threatens Bird Migration

From the New York Times:

Climate Change Threatens Migratory Birds, Report Says


March 12, 2010

WASHINGTON — Changes in the global climate are imposing additional stress on hundreds of species of migratory birds in the United States that are already threatened by other environmental factors, according to a new Interior Department report.

The latest version of the department’s annual State of the Birds report shows that nearly a third of the nation’s 800 bird species are endangered, threatened or suffering from population decline.

For the first time, the report adds climate change to other factors threatening bird populations, including destruction of habitat, hunting, pesticides, invasive species and loss of wetlands.

The report said that oceanic and shore birds are among the most vulnerable to climate change because of rapidly changing marine ecosystems and rising sea levels.

The conclusions are the result of a collaboration of federal and state wildlife agencies, universities and conservation groups

So these “conclusions” are effectively useless, except as propaganda.

And in case there is any doubt here is an except from the US Department Of Interior’s report, The State Of The Birds:

The State Of The Birds – Summary

Birds in every habitat will be affected by climate change.

In this report, we address climate change–focusing attention on what may be in store for our nation’s birdlife, and the stories the birds themselves are telling us about the changes that are happening even now.

Birds in every terrestrial and aquatic habitat will be affected by climate change, although individual species in each habitat are likely to respond differently. We assessed the relative vulnerability of each United States bird species, based on five biological aspects of sensitivity to climate change, as well as the exposure of each species’ habitat to climate change in the near future. We then categorized species as showing High Vulnerability (a vulnerability score of four or more), Medium Vulnerability (a vulnerability score of two or three), or Low Vulnerability (a vulnerability score of zero or one).

The results indicate that a majority of birds dependent on oceans, and birds on Hawaiian Islands, are highly vulnerable to climate change. Birds in coastal, arctic/alpine, and grassland habitats, as well as those on Caribbean and other Pacific islands show intermediate levels of vulnerability. Most birds in aridlands, wetlands, and forests show lower overall vulnerability (see bar graph)…

Big Changes are in Store for Oceanic Birds

All 67 oceanic bird species, including albatrosses, petrels, tropical terns, tropicbirds, frigatebirds, and puffins are vulnerable because of their low reproductive potential, use of islands for nesting, and reliance on rapidly changing marine ecosystems. Seabirds such as Laysan Albatross and Bonin Petrel that are restricted to nesting on low-lying islands are in danger of losing their breeding habitat as sea levels rise. To provide oceanic bird populations with the best chances of adapting to climate change, we must reduce existing threats from overfishing, fisheries bycatch, and pollution. We must also take proactive measures such as removing invasive species and protecting existing or potential breeding colonies on high islands.

Sea Level Rise and Increased Storm Activity Threaten Coastal Birds

Rising sea levels are expected to inundate or fragment low-lying habitats such as salt marshes, sandy beaches, barrier islands, and mudflats. Increasing frequency and severity of storms and changes in water temperatures will impact quality and quantity of coastal habitats and alter marine food webs. Beach-nesting terns, highly specialized Saltmarsh Sparrows, and birds dependent on marine waters are among the most vulnerable species. Migratory species such as shorebirds are also vulnerable to changes in stopover and wintering habitats. Conserving coastal habitats will require planning and management to facilitate birds’ movement and resilience.

Accelerated Changes in Arctic/Alpine Regions

Increased temperatures will drastically alter surface water and vegetation in the arctic, resulting in major changes in bird abundance and distribution. White-tailed Ptarmigan and rosy-finches may disappear from mountaintops as alpine tundra diminishes. Species that depend on grass-sedge tundra for breeding, such as the Black Turnstone, could lose their tundra breeding habitat. Minimizing human-caused disturbance to low-lying tundra and high-elevation alpine habitats may help the most vulnerable species adapt to changes…

Given that the sea levels have not risen, and that global temperatures have not gone up in 15 years, you have to wonder just what they are panicking about.

And why our government is using our money to propagandize to us.

    Reader’s Digest version:

    “Birds in every habitat will be affected by climate change……..

    so you will have to hand over everything you own to fat greedy people who are contemptuous of everything about you. You will have to give them your daughters and sons, and let them kill your parents and uncles and aunts. If you are lucky, you will be granted the priviledge of living a hard-scrabble existance with the sole purpose of serving your masters.

    If you complain, it will be worse.”

    Quail are tasty.

    That is all.

    Some global warming. Here in central Florida we have experienced the coldest winter since ’78-’79. At least that I can remember.

    We’ve lost probably 80% of our landscaping and deck plants to freezes and frost. And that’s after trying to protect them.

    Perhaps this is one of O’Balmy’s jobs plans…to bring in more illegals to work the nurseries and in landscaping.

    So much for Algore’s theories

    If the birds are experiencing problems…its probably just because t hey are trying to avoid all the ice.

    Seabirds such as Laysan Albatross and Bonin Petrel that are restricted to nesting on low-lying islands are in danger of losing their breeding habitat as sea levels rise.”

    Don’t you just love that statement? Let’s say for the moment…that the seas rise….wouldn’t there just be new “low-lying islands” created at the edge of the higher waters? So, I’m sorry….what’s the problem here?
    How fast wold this happen…and how far away would these new islands be from the old nesting grounds be that the birds would lose their way? Give me a break!

    …..”and rising sea levels…..”


    Wouldn’t that create more habitat for waterfowl?

    Wouldn’t warmer temperatures mean they wouldn’t have to fly south for the winter?

    Think of the energy that would save.

    Think of the people that would free up at the TSA to do other things.

    Think, people, think!!

    Saw the first robin yesterday.

    When do the swallows return to Capistrano and what bird returns on St. Joseph’s day? And where?



    “The miracle of the “Swallows” of Capistrano takes place each year at the Mission San Juan Capistrano, on March 19th, St. Joseph’s Day.”

    Someone keep us posted if I forget.

    How about our non-endangered species, you know, that flat-out whipping you the bird,”BIRD”. This one’s for you, Big Government. Has OSHA been notified? I seem to be straining myself.

  7. wirenut says:

    U NO, The cork is about to come off the bottle.
    Pencil-necked government euphorians will be unleashed among the masses in the near future. Small business goes in the toilet. Big Gov, in-flicks it’s will. None of us will have a job, but we’re all safer.

      “Small business goes in the toilet.”

      The easier to unionize the workers, my little pretty.

      Heard of day care in Michigan?

    More Liberal Garbage From Their Playbook

    Guys….this is right out of page 7 of the liberal playbook, and it’s so so old!

    *Blame everything on the political issue of the day.
    1. Weather / Environment = …because of global warming.
    2. Economy = Bush’s fault.
    3. Health Issues = Because of a bad health care system.
    4. Immigration or Opposing Obama = Racism.
    5. Any report that makes black people look bad = racism.

    Don’t think so? They have been blaming Ronald Reagan for everything since 1980. That’s 30 years and counting.

    That is how you beat it into the heads of the stupid masses, so they can have an easy digestible sound bite for the liberal way of understanding the way things are. Page 7…..

    So, the writer states that “climate change” places additional “stress” on migratory birds which “endangers” the birds. Let me think.
    Oh yeah, this is the same media that warns us about anti-depressant and other medications, such as Viagra, being found in our water supply. Now that I think about it, it seems we’ve solved the birds’ problems.
    With all the anti-depressant medication in the water supply, we will ease the birds’ stress. Further, with sexual supplements in the water supply, the birds should be going at it like gangbusters.
    If the birds need more stimulation to ease their stress, perhaps we can come up with a government program to deliver bird porn, via broadband, to their nesting sites.
    Problem solved.
