We are now in the midst of the big bird migration time of the year and weather radar can help documents the huge flux of birds overhead.
But even more fascinating, we can skillfully predict bird migration using numerical weather prediction.
One of my favorite sites to check out bird migration is BirdCast, run by the Cornell Laboratory of Ornithology. I really appreciate this group and as an undergrad at Cornell I frequently visited their Sapsucker Woods Wildlife Sanctuary.

In 2019 bird researchers published Rosenberg et al “Decline of the North American Avifauna”, reporting a decline in 57% of the bird species. They estimated a net loss of nearly 2.9 billion birds since 1970, and urged us to remedy the threats, claiming all were “exacerbated by climate change”, and we must stave off the “potential collapse of the continental avifauna.” Months before publication the researchers had organize and extensive media campaign. Typical doomsday media like the New York Times piled on with “Birds Are Vanishing From North America” and Scientific American wrote, “Silent Skies: Billions of North American Birds Have Vanished.”
As I have now been sheltering in place, I finally had ample time to thoroughly peruse Rosenberg’s study. I had a very personal interest in it, having professionally studied bird populations for over 20 years and had worked to restore their habitat. I also had conducted 20 years of surveys which were part of the study’s database. Carefully looking at their data, a far more optimistic perspective is needed. So here I join a chorus of other ecologists, as reported in Slate, that “There Is No Impending Bird Apocalypse”. As one ecologist wrote, it’s “not what’s really happening. I think it hurts the credibility of scientists.”
Banning neonic pesticides in wildlife refuges would hurt birds, bees, other wildlife and people
Guest post by Paul Driessen, – Re-Blogged From WUWT
The House of Representatives Committee on Natural Resources recently approved HR 2854, the 2019 Protect Our Refuges Act, prohibiting the use of neonicotinoid insecticides in any of the nation’s 560 National Wildlife Refuges, some of which are the size of Delaware and even Indiana. The legislation will now be considered by the full House, while a companion bill (S 1856) makes its way through the Senate.
The legislation is unnecessary, misguided and based on embarrassingly bad science. Rather than protecting our refuges, it would force farmers to use other insecticides that truly are harmful to bees, birds and other wildlife (and even humans), or end programs to grow crops that nourish refuge inhabitants and visitors. Sadly, the forces driving it forward are par for the course on far too many ecological issues.

One of the best things about my morning emails from the American Association for the Advancement of Science of America (Google “Dodgeball” if you don’t get the joke), is that there’s almost always at least one article deserving of ridicule…
Many state birds may flee their home states as planet warms
By Eva Frederick Oct. 10, 2019
State birds can be a source of tremendous local pride—but as the climate warms, at least eight state birds may no longer call their native state home, The New York Times reports. In a new study, National Audubon Society scientists…

For reasons that will soon be evident, the comments on my previous wind turbine post reminded me of a long-ago sunset dinner with my gorgeous ex-fiancée on the verandah of a lovely treetop restaurant on Pohnpei island in the tropical Pacific.
The only “fly in the ointment”, as is often the case in the tropics, was … the flies. And various other tropical flying insects. So the owners had thoughtfully installed one of those insect electrocution devices with the exposed power wires that go BZZZT every time another fly hits the wires, is electrocuted, and falls out of the sky.
