Overview
"Discovery consists of seeing what everybody has seen and thinking what nobody has thought."
  Albert Szent-Gyorgyi, Nobel prize for identifying and working with Vitamin C

Not much new from this Spring’s radar for hawks. We’ll see some from Lake Ontario, but there’s a new capture from Duluth!
On the subject of radar and weather, the Lab of Ornithology had a radar seminar in June. Also there’s some radar and climate news.
That insects are disappearing in large numbers is news. Finally, a nice Sunday email site on thinking and reading.

Hawks On NEXRAD

"The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' (I found it!) but 'That's funny ...'"
  Isaac Asimov, SciFi writer

Big overwater flight on 31 March (top, screenshot), so TVs and adult northern RTs primarily. Early overwater flights begin showing on radar around 20 March.
What started pelagic, this 21 May flight (bottom, animation) was bent inland by a wind shift. From Nine Mile Pt., the flightline bends inland below the 81 map marker, before turning N over Stillwater Reservoir and up over the Tug Hill.

Derby Hill’s Big Day (7K), shows a strong inland element that might have been a 20K+ day at/around the Sodus area.


New! Just happened to be checking Cleveland radar, and I went over to Duluth. On 28 May there was a strong, late BW flightline just inland from the shoreline and therefore the hawkwatch. The Duluth city and Wisconsin shoreline radar noise is of unknown origin. The Silver Bay inland jog is probably explainable by those who know the area. 

 

Interesting raptor information.

Bonus NEXRAD

At the Ontario-NYS border and right along the shoreline, a small burst of hawks are visible. After this animated GIF are two still images of hawks along the N side of Lake Erie.

Two still images from Cleveland showing hawks that have crossed at Detroit and are making their way along the N shore of Lake Erie. Some will then move N of Lake Ontario, while some will enter NYS and move along the S shoreline.

This still image depicts of line of dragonflies in mid-June, N of Buffalo so likely entering from Ontario... like last year. At Derby Hill, there were many in the air on this day.



Silence of the Insects
The study that showed a huge decline in European insects, over time: much talk followed.

PBS Nature did a show on butterflies that involved long-distance migration, stable isotope work, and radar(!) to find the starting and wintering point for the Painted Lady across Europe and Africa! The whole episode is behind a membership/paywall, unless you are Torrent proficient (nature.s36e12.sex.lies.and.butterflies.hdtv.x264-w4f.mkv). Otherwise, watch for the summer rerun.

Weather/Cimate
23 June 1988 was the 30th anniversary of the day Dr. James Hansen famously testified to Congress on the dangers of climate change. Here are a few links with links within about Hansen and what followed.

The Global Conveyor Belt, the action that circulates/regulates ocean currents both on the surface and depths, is slowing. In addition to offering a fine explanation of how this effects climate, this link opens with a nice simple PowerPoint-like presentation.

On 4 June, the Lab of Ornithology had a (now occasional) Monday Evening Seminar on “Dark Ecology”… birds on nocturnal radar. Three Lab post-docs each did a third of the program: Cecilia Nilsson, Kyle Horton, and Adriaan Dokter. I went down for the talk, but it was live-streamed, and now available for viewing online. Like “Sex, lies and butterflies” (above), this is a must watch.

Kyle then sent me this short piece on airspace as habitat with a hawk radar example and many nice beginner references for those with academic library access.

BRAIN PICKINGS BY MARIA POPOVA
First thing Sunday morning, subscribers find her offering in their Inbox. Quotes, references, and thinkers. Most often illustrated with wonderful drawings from children’s books (which you will want to read and buy). Often as not, there is a natural world theme to be found. Here are some recent examples:

Truth and beauty. Art and science. Entries here will be on that flightline, although I will stray from the hawk-part on occasion, or will I? I aiming this beast at hawkheads and/or the young seasonal revolutionary biologists. It's for the flexible and young-at-heart too.
Comments, questions, excited utterances, and/or exasperated afterthoughts from you, dear reader, are welcome and will receive a reply. — Tom Carrolan

Original recipe Hawksaloft.com
The Hawksaloft.com website was launched in 1997, following three years of printed handbills, plus numerous emails, all voicing my alt.hawkwatching ideas in New England. If you've been here before, the original site is archived in all its old-timey graphic glory. To navigate the old way, just click on Psychedelia the Hawk Owl and be transported back in time... trippy. Any bookmarks or links found anywhere online still work.
