How many birds died in the BP oil spill?

MLast week at a Deepwater Horizon response press conference, Federal On-Scene Coordinator Adm. Paul Zukunft told National Public Radio’s Debbie Elliott, “We did have you know certainly a loss of wildlife, but in comparison we had about 2300 dead oil birds and Exxon Valdez, that number was nearly 225,000. So again, the impact could have been much worse than what it was.”

But it is too early to know what the impact of the Deepwater Horizon spill has been, or will be, on bird populations. We do know that the count of carcasses, and the number of live, oiled birds that are rehabilitated, does not begin to enumerate the impact of the spill on populations. It does not reveal the actual death toll, nor the cost to birds in terms of their long-term ability to survive and reproduce.
The complexities are numerous and lead to confusion when bird numbers are reported publicly.
Comparing the count of dead birds that were collected with oil visible on their feathers from the Deepwater Horizon spill to the estimated toll from the Exxon Valdez oil spill is like comparing, well, apples to zebras.
The 2,263 birds collected dead with visible oil on their bodies is an actual count done, as all actual counts are done, imperfectly.
The 225,000 from the Exxon Valdez is an estimate, calculated with a complex algorithm incorporating the death toll, numbers of oiled, live birds, and models and other estimates to create an educated, scientific guess about how many birds died....more

Canaries in the Climate Change Coal Mine?

Nearly 60% of the 305 species found in North America in winter are on the move, shifting their ranges northward by an average of 35 miles. Audubon scientists analyzed 40 years of citizen-science Christmas Bird Count data — and their findings provide new and powerful evidence that global warming is having a serious impact on natural systems. Northward movement was detected among species of every type, including more than 70 percent of highly adaptable forest and feeder birds.
Only grassland species were an exception - with only 38 percent mirroring the northward trend.

But far from being good news for species like Eastern Meadowlark and Henslow's Sparrow, this reflects the grim reality of severely-depleted grassland habitat and suggests that these species now face a double threat from the combined stresses of habitat loss and climate adaptation.
It is the complete picture of widespread movement and the failure of some species to move at all that illustrate the impacts of climate change on birds. They are sending us a powerful signal that we need to 1) take policy action to curb climate change and its impacts, and 2) help wildlife and ecosystems adapt to unavoidable habitat changes, even as we work to curb climate change itself.

Umberto Eco cree que el hombre es el enemigo de los libros y no Internet.

Roma, 13 may (EFE).- El escritor italiano Umberto Eco, uno de los intelectuales europeos de mayor prestigio, afirma que el principal enemigo de los libros no es Internet, sino el ser humano, que los censura y confina a bibliotecas inaccesibles.

Roma, 13 may (EFE).- El escritor italiano Umberto Eco, uno de los intelectuales europeos de mayor prestigio, afirma que el principal enemigo de los libros no es Internet, sino el ser humano, que los censura y confina a bibliotecas inaccesibles.
Los enemigos de los libros son "principalmente los hombres, que los queman, los censuran, los encierran en bibliotecas inaccesibles y condenan a muerte a quienes los han escrito. Y no, como se cree, Internet u otras diabluras", afirma el literato en una entrevista que publica hoy el diario turinés "La Stampa".
"Internet enseña a los jóvenes a leer, y sirve para vender un montón de libros", añade

De lege agraria nova

Segundo a Sala de Imprensa da U.E., "O primeiro diploma legislativo da UE em favor da natureza, a Directiva Aves, celebra o seu 30.º aniversário a 2 de Abril.

Esta directiva é uma das maiores conquistas da política europeia do ambiente e a sua importância é fundamental para a estratégia da UE tendente a travar a perda da biodiversidade. A Directiva Aves desempenhou um papel crucial na inversão da tendência para o declínio de algumas das espécies de aves mais ameaçadas da Europa, nomeadamente através da sua rede de zonas de protecção especial (ZPE).

Graças a uma acção orientada da União Europeia, dos Governos nacionais, de ambientalistas e de voluntários no sentido da aplicação prática da directiva, o futuro de inúmeras aves é agora muito mais promissor.

É o caso do colhereiro europeu (Platalea leucorodia), da águia-rabalva (Haliaeetus albicilla) e da águia-imperial ibérica (Aquila adalberti). Existem actualmente cerca de 5 000 ZPE, que cobrem mais de 10% do território da UE e fazem parte integrante da rede ecológica Natura 2000.

A Directiva Aves constitui um excelente exemplo de partilha de responsabilidades e de cooperação entre os 27 Estados-Membros da UE.."
