Drawing into the spectrogram is a fun trick. I would really like to know how much data you can store in that bird using some digital modulation method such as FSK (frequency shift keying).

There could even be multiple carriers in the signal.

It would be even cooler if the bird were to preserve phase. Then you could use PSK!

Here's what 4096 carriers looks like.

A totally new meaning for carrier pigeon.

The video shows the bird capable of remembering and reproducing 5-10 frequency graphs simultaneously (which you'd need to draw a picture), so you can multiplex those.

Or same carrier, but different sets of frequency keys for each stream.

Maybe they do, someone should ping Ben to test that :D
