I listen to quite a bit of late-night radio while drawing and lately I’ve heard some interesting stuff about how birds are beginning to sound different. This is leading people to speculate that their navigational systems might be disrupted somehow, whether by an approaching asteroid, rogue planet, pole shift, etc.
One thing which resonated with me was when someone remarked that they had observed a bird emitting some sort of electronic sound. So, rather than draw the analog signal, I drew more of an analog to digital conversion (which is actually backwards, but the more accurate depiction wouldn’t illustrate well). This is basically the thumbnail and concept sketch of that. I should have an actual finished version of this in the next few days.
