Finally back after too long in other forums. In our morning deck count, we hit 35 spp., including my first golden-winged warbler. (Yeah I am that much of a newbie.) Is migration already starting?

Shorebird migration started by the third week of July. Early migrant warblers like Golden-winged, Canada, Prothonotary, Kentucky, etc. should definitely be moving by now. Congrats on the Golden-winged. Sadly that's become a tough bird in our area anymore.

Thanks for the update. Part of my problem was my near deafness to high frequencies, so I never heard warblers till this spring after I finally got hearing aids. A godsend. It's a whole new world for me now. I spotted that guy about 120 feet away as a flash of yellow that just didn't look like a goldfinch. He then kindly came over to work our elm and birch trees next to the deck where we got great views. Gone by the time I got my camera though.

FYI the Eastern population of Willets may already be gone. Any Willet you see down near the coast after mid-August is almost guaranteed to be from the Western population. There have been proposals to split these into two species and I personally think that has merit. They have different plumage characteristics, body shape differences, vocalization differences, completely different breeding habitat, and they're genetically isolated. They seem to be as good a candidate as many and better than some.

If you've got public schools paid for by taxpayers, you're in a socialist nation. If you have public roads paid for by taxpayers, socialist nation. If you've got public defense (police, fire, military, coast guard) paid for by tax dollars, socialist nation. If you're in a nation that has nationalized or localized delivery of services that are not paid for by users alone, you're in a socialist nation- the only question is how socialist. As I see it, we have the military pay to protecting the shipping lanes for our fuel needs which makes up very socialist. In a capitalist nation, the people supplying the oil would pay for their own defense force.

Great bird—but amazing pic! For ten seconds I thought it was a stone statue of a mythical two-headed bird, in the same vein as the Germanic two-headed eagle.

Well, her fashion business allegedly went pear-shaped so perhaps she's been at a bit of a loose end. At least this doesn't look like work the Devil has found for her idle hands, but then again, what do I know?

A bird drone programmed with threat avoidance behavioral characteristics of different types of birds is starting to be used to move birds from airports to reduce the threat of bird strikes for planes. (That seems kind of birdist since in these interactions are usually lethal to the bird.) Knowing how different birds will react is key to moving the flock away from the flight path without causing them to panic and scatter in multiple directions.

Quote

The CalTech study, led by aerospace professor Soon-Jo Chung and published this August in IEEE Transactions on Robotics, required one crucial first step: figuring out how flocks work, from how they communicate to how they fly in perfect formation to (most importantly) how they respond to threats.

The team discovered a few key takeaways. First, flocks don’t have a centralized communication system. Chung told The Daily Beast that each bird only passes messages to its immediate neighbors, meaning that “information propagates, like a wave.”

Different species of birds communicate threats at different distances, Chung added. Flocks of egrets changed their path when a drone was about 20 meters away from the nearest bird, but loons didn’t react until the drone got much closer, about 10 meters away.

Second, this tightly-controlled communication system only goes so far. If a threat flies too fast or too close to the birds, they’ll panic and scatter, making them unpredictable and uncontrollable.

All of this information, Chung said, was vital in building the drone’s algorithm. “If you can know how this flock will react,” Chung told The Daily Beast, “how fast, how they’re going to change their direction—if you can know that, you can use that information in your herder”—what the team calls the drone.

And that’s exactly what CalTech did. Once the team understood the birds’ flocking dynamics and threat response behavior, they replicated it in a mathematical model.

The resulting algorithm, which uses either camera footage or more sophisticated avian radar data to track incoming threats, helps the drone strike the perfect balance: it flies close enough to the birds that they register a threat and change course, but not too close that it scares them into scattering. (You can watch a video of a simulated drone in action here.)

So far, it’s working. As part of the August study, Chung and his team traveled to Daejeon, South Korea, to see if an algorithm-guided drone could divert flocks of local egrets and loons away from a designated safe zone. In both cases, Chung said, the drone succeeded.
