The phenomenon of multiple prey animals swarming larger predators to drive them off is known as mobbing.[0] Crows seem to do it quite readily. Very cool that you got to see it! [0] https://en.wikipedia.org/wiki/Mobbing_

See my reply to your sibling comment - I do in fact mean spectral complexity at any given moment, not just over the course of the song. Many species of birds can and do vocalize with complicated timbre, including harmonic stacks, buzzes, cl

I should have been clearer. I am also talking about moment-to-moment spectral complexity or entropy. I agree that the point TFA is suggesting seems to be about the spectral complexity at any given moment in song - what you might call the ti

I don't want to detract from the images, or the work that went into this, but, er, there are a lot of types of birds. Just among passerines (songbirds), we're talking over 6,000 species. So any sweeping statement like "bird

The concept is interesting, but I'm a little leery of the detail that the benchmark performance reported is in each case "the best run out of 100". One can claim, thus, only that this sort method's near-best-case perform

If only this were true. (By "modern" I assume you mean densely-spaced [~10um] multi-pad linear silicon probes, the NeuroPixel being the most celebrated example among the non-specialist public.) What many pads close together can gi

I don't want to detract from the cleverness here, but I believe your benchmarks could use some work. Here are a few suggestions: 1. Simply testing something 1000 times and (presumably) presenting the arithmetic mean is not very informa
