| >I thought he'd transmit a PNG over a modem, get a bird to memorise that and play it back. That's essentially what he has done. Except he did the modulation/demodulation with audio software (and, technically, stored a monochrome bitmap, not a PNG). Dial-up modems encode data in audio-frequency. Later modems used phase-shift keying¹, but the very early ones used frequency-shift keying², which is essentially encoding data in a frequency graph - i.e., drawing a line in a spectrum analyzer. Drawing a bird in a spectrum analyzer is packing much more data than that; it's like playing several of those streams at once. The bird has shown itself to be capable of remembering and reproducing multiplexed frequency-keyed streams. >With enough birds I imagine you can store quite a bit of data. Takes saving to the cloud to another level.
