Murmuration

Never Again Would Bird's Song Be the Same"
Robert Frost, 1942

He would declare and could himself believe
That the birds there in all the garden round
From having heard the daylong voice of Eve
Had added to their own an oversound,
Her tone of meaning but without the words.
Admittedly an eloquence so soft
Could only have had an influence on birds
When call or laughter carried it aloft.
Be that as may be, she was in their song.
Moreover her voice upon their voices crossed
Had now persisted in the woods so long
That probably it never would be lost.
Never again would birds' song be the same.
And to do that to birds was why she came.

GARDEN UPDATE
Pretty weather today and getting hotter. Makes everyone frisky! Had a nice talk with a friend who has a green house he built, and a large growing stock. He just built what he calls a 'berry house'- simply a structure covered with chicken wire to keep out critters. He consolidated all his berries in there, and doesn't have to fight the raccoons for berries any more!
MURMURATION
I find nature phenomenon fascinating and wish I had an opportunity to see them! With the advent of video, we can now accomplish that.

What is a murmuration? Video of a massive starling flock turning and twisting over a river in Scotland has gone viral, and with good reason. Flocking starlings are one of nature’s most extraordinary sights: Just a few hundred birds moving as one is enough to convey a sense of suspended reality, and the flock filmed near Gretna, Scotland contained thousands.What makes possible the uncanny coordination of these murmurations, as starling flocks are so beautifully known?


No one knows why they do it. Yet each fall thousands of starlings dance in the twilight above Gretna,Scotland . The birds gather in magical shape-shifting flocks called murmurations, having
migrated in the millions from Russia and Scandinavia to escape winter’s bite. Scientists aren’t sure how they do it, either. Even complex algorithmic models haven’t yet explained the starlings’ acrobatics, which rely on the tiny birds' quicksilver reaction time of under 100 milliseconds to avoid aerial collisions—and predators—in the giant flock.
Until recently, it was hard to find an explanation. Scientists had to wait for the tools of high-powered video analysis and computational modeling. And when these were finally applied to starlings, they revealed patterns known less from biology than cutting-edge physics.

Starling flocks, it turns out, are best described with equations of “critical transitions” — systems that are poised to tip, to be almost instantly and completely transformed, like metals becoming magnetized or liquid turning to gas. Each starling in a flock is connected to every other. When a flock turns in unison, it’s a phase transition.




At the individual level, the rules guiding this are relatively simple. When a neighbor moves, so do you. Depending on the flock’s size and speed and its members’ flight physiologies, the large-scale pattern changes. What’s complicated, or at least unknown, is how criticality is created and maintained.

It’s easy for a starling to turn when its neighbor turns — but what physiological mechanisms allow it to happen almost simultaneously in two birds separated by hundreds of feet and hundreds of other birds? That remains to be discovered, and the implications extend beyond birds. Starlings may simply be the most visible and beautiful example hinting at universal principles yet to be understood.



Here's the video. Be aware it has some stop action in it at the beginning but hang with it, it's worth it! Warning, pretty amazing stuff!(For our mobile users, if you don't see a video below, click here.)
