Phil Berardelli (ScienceNOW Daily News) has published a neat story here on the benefits of a specific configuration of vertical-axis wind turbines (VAWTs; example here).
VAWTS, arranged in a pattern that mimics schooling fish, can provide a similar energy output to traditional, horizontal axis wind turbines (HAWTs) on approximately 1/100th of the land area. Thus, VAWTs, already a preferred design for conservationists because they appear to present a far lesser threat for bird collisions, could also provide a substantial benefit in terms of land use conversion. That is, of course, unless greedy developers simply take this information to mean that they can reap 100X the power output from the same enormous land area they want to develop . . .

My favorite beginner’s field guide 25 November 2009

Few people are familiar with this guide, but it is a little gem!
I’ve been birding for about 35 years, so I’ve had lots of experience with field guides. I’ve also spent a lot of time introducing beginners to birding, so I think I have a pretty good sense of what helps to get them started. To that end, this guide has several things going for it.
First, it’s small: 4.5 X 7.5 X 0.3″. This is a thin, lightweight, easy-to-take anywhere guide. I love my massive Sibley guide, but a lot of beginners are turned off by its heft. No such problem with Coe’s guide.
The guide owes its lean and mean profile to restricted coverage. This is an eastern birds guide that will serve people well from the Atlantic Coast to the High Plains. For beginners, this means they won’t be distracted by things like Cordilleran Flycatcher. But the guide is also restricted in that it doesn’t illustrate _every_ species from the East, either. For example, Acadian Flycatcher is described, but not illustrated. For the hard core birder, this can be maddening, but if you think like a beginner, you appreciate that no illustration of an Acadian would actually help separate it from the illustrated Willow. Alder Flycatcher isn’t even mentioned. That’s an outrage, but again, only if thinking like an experienced birder. To my mind, and apparently Coe’s, anybody ready to distinguish Alder from Willow by voice should have already moved up to a more advanced guide.
Those species that are included are mostly beautifully rendered with realistic postures and expressions. I’m sure there are exceptions, but I find Coe’s plates to be lovely examples of high art that express true realism. Most species that are illustrated include (as appropriate) males, females, immatures, and seasonal changes.
The range maps are very coarse – basically an outline of the central and eastern U.S. (+ a bit of Canada) with no state outlines included. Again, however, they’re detailed enough for a beginner in Vermont to think twice before ticking Summer Tanager off his backyard list.
For me, the two great advantages of this guide lie in its text and its rendering of plates in predictable habitat backgrounds. All species illustrations are accompanied by a descriptive paragraph that includes hints on habitat, voice, and visual identification. The habitat backgrounds, however, are really underrated in terms of their ability to convey to beginners what they’re _most likely_ looking at. For example, Coe provides a wide angle illustration of an agricultural landscape with a Red-tailed Hawk perched on a utility pole in the distance. His thrushes are painted against a backdrop of moist forest leaf litter (Veery), dark green coniferous branches (Swainson’s), and citron-green lower canopy on a bright morning in early June (Wood Thrush). I was first taken by this guide when I noticed in the plates in the introductory material that include multiple species together in likely settings. For example, the “summer” page of “Backyard Birds” shows a Chimney Swift in the air, a Northern Mockingbird on a telephone wire, American Robin and Chipping Sparrow on the lawn, and Common Yellowthroat and Song Sparrow in the bushes beyond. The first few pages of this guide alone could do wonders to instill confidence in a beginning birder that it is possible to “learn all those birds.”
So, no, this guide doesn’t offer tremendous insights into separating the dowitchers from each other, but it’s a tremendous resource for the vast majority of people out there who have no idea that there such a thing as a “dowitcher” in the first place. What’s more, this book can get people interested in taking their fledgling interest in birds to new heights.

Check out how schoolchildren in Colombia celebrate the arrival of migrant birds from the North! This is exactly the sort of thing we need to do with kids here in the States. I think we need a “Stillwater Scissortail Celebration!” next spring.

Great example of a conservation success story:
Brown Pelican Populations Recovered, Removed from Endangered Species List
Salazar: Brown Pelican Recovery is “an Amazing Success Story”
WASHINGTON, D.C. — Secretary of the Interior Ken Salazar, Assistant
Secretary for Fish and Wildlife and Parks Tom Strickland and U.S. Fish
and Wildlife Service Director Sam Hamilton today announced that the
brown pelican, a species once decimated by the pesticide DDT, has
recovered and is being removed from the list of threatened and
endangered species under the Endangered Species Act.
“At a time when so many species of wildlife are threatened, we once in a
while have an opportunity to celebrate an amazing success story,”
Salazar said. “Today is such a day. The brown pelican is back!”

THE BIRDING COMMUNITY E-BULLETIN
November 2009
This Birding Community E-bulletin is being distributed to active and concerned birders, those dedicated to the joys of birding and the protection of birds and their habitats. You can access an archive of past E-bulletins on the website of the National Wildlife Refuge Association (NWRA):

RARITY FOCUS
On the morning of 12 October, a Brown-chested Martin was discovered by Jeremiah Trimble, Matt Garvey, and Marshall Iliff at the Cumberland Farms on the Halifax/Middleboro town line in southeastern Massachusetts. One race of this species is an austral migrant from southern South America, and there are only five previous convincing sightings for North America since 1983 (Massachusetts, Florida, New Jersey, Connecticut, and Arizona), including several with complete documentation (i.e., specimen or photograph).

Where we wouldn’t put wind turbines 9 November 2009

Let’s just say for the sake of argument that wind power actually was as “green” as developers and lobbyists would have us believe – a big stretch, but bear with me. It would make good energy sense to erect towers and transmission lines anywhere we had favorable winds, right? But I suspect there are some example of places that – again for the sake of argument – were windy enough for development to make sense but were otherwise so important to us that we wouldn’t actually want the spot developed for wind power. Here are a few examples:
Ellis Island?
Fenway Park?
The Rose Bowl?
Arlington National Cemetery?
Gettysburg National Park?
Colonial Williamsburg?
Disneyland?
Old Faithful?
Mount Rushmore?
Yosemite National Park?
The Hollywood sign?
Surely it’s only the truly deluded (or simply the biggest jerks) who would ever consider drastically altering the character and quality of these special places by establishing wind turbines and transmission lines through them. Why, then, can’t we also agree that the biggest expanses of open grassland in the American West – places that are especially valuable for their ability to support prairie wildlife that generally avoid any kind of human development – are also off limits? Why can’t we recognize that Appalachian ridges should not be sullied with tubines – turbines that are lethal obstacles to thousands of migrating raptors each fall and spring?
We must, as a progressive society, recognize that the free-for-all attitude of wind development has to stop. In its place, we need serious attention given to identifying those places and those resources that we do not want encroached by tubines and transmission lines.
