A music and science lover has revealed that some birds can store and retrieve digital data. Specifically, he converted a PNG sketch of a bird into an audio waveform, then tried to embed it in the song memory of a young starling, ready for later retrieval as an image. Benn Jordan made a video of this feat, sharing it on YouTube, and according to his calculations, the bird-based data transfer system could be capable of around 2 MB/s data speeds.
Only a matter of time before megacorps put ads and a subscription service on bird calls, now. 😫
Inb4 Doom can now run on birds.
Latency tho…
How useful would this have been back at the dawn of computation, I wonder?
They didn’t have ultrasonic microphones at the dawn of computation
Pigeon guided missile but instead of pigeon it’s a parrot and sings relevant source code in hex and an interpeter assembles it.
(I hate the last 4 words that sentence I made.)
Birds are totally organic organisms. Rightttttt. BIRDS ARENT REAL!!!
They’re just covering up the truth of the time cube
Not to be a wet blanket, but every time this comes up I get annoyed by some factual inaccuracies in the articles about this. It is not digital! He drew an image on a computer, but converted it to an analogue spectrogram to store on the bird. That’s neat as hell, but it’s not digital. The image that he got back was slightly corrupted.
Now I would be fascinated to see a follow-up seeing if you can actually modulate a digital signal and have is survive a round trip through the bird bit-for-bit accurate. I suspect in reality it would be much lower data rate, but definitely not nothing!
By your definition nothing can be digital since the world is analog. Even the bits in your CPU are voltages in transistors. As such, every real life signal can be distorted.
The point with digital transfers is that you round it back to either 0 or 1, hoping that no bits are distorted enough to have any loss at all.
Exactly. Digital logic, when implemented in analogue, generally have to have forbidden zones where a signal in that range is considerer invalid. Regardless of implementation, digital is about the discretized logic of the system. That is explicitly the whole point of digital: Minor analogue distortion does not change the information content of the signal unless it is so bad as to flip a bit.
Minor analogue distortion does not change the information content of the signal unless it is so bad as to flip a bit.
This isn’t true in the general case. In the real world, you can have all kinds of distortions: random noise, time shifts, interference from other signals, etc.
You don’t usually see the effects of these because the protocols are designed with the communication channel characteristics in mind in order to reproduce the original signal.
Using birds is just another communication channel with its own distortion characteristics.
That’s exactly what they said.
Precisely… And digital modulation’s entire purpose is for a digital signal to survive those distortions bit-for-bit perfect. Even if we call the digitally-generated spectrogram digital information, the bird simply did not reproduce it exactly. Whatever time, frequency, and amplitude resolution you apply to the signal, if it’s low enough that the bird reproduced the signal exactly within that discretized scheme, then it simply did not achieve 2 MB/s. I would bet that the Shannon capacity of this bird is simply nowhere near 2 MB/s.
If your argument is that the bandwidth calculation is incorrect, then sure I think that’s fair.
But I don’t think it’s correct to say it’s not a digital channel juts because it doesn’t have optimal bandwidth.
Gozz is correct. You’re misunderstanding the nature of a digital signal. What the author did was convert a digital signal to an analog signal, store that analog signal on a bird, then record that analog signal. Whether it was redigitized after the fact is irrelevant. It is not a digital process end-to-end. This is the same as if I were to download a YouTube video, record that video on a VHS tape, then redigitize that video. Not only would the end result not be a bit for bit match, it wouldn’t be a match at all despite containing some of the same visual information, because it would be the product of a digital-analog-digital conversion.
That’s not really how it works in the real world. Usually you have both bandwidth and noise constraints.
Sure you can send something like a square wave but this isn’t practical for real communication channels. Typically you’re sending many sine waves in parallel with multiple amplitudes and phase offsets to represent a sequence of bits (QAM). Then on top of that you’d encode the original data with both a randomizer (to prevent long runs from looking like nothing) and error correction. So usually the system can handle some level of distortion.
What you’re hoping is that by the time the data reaches the user (really, Layer 3), all the errors have already been handled and you never see any issues.
The bird is just another type of noisy channel with its own distortion characteristics.
The point is that at the physical layer you still have a well defined log likelihood test to produce digital information. That’s why QAM lasted so long even though it is not power efficient - because it has an analytical likelihood function.
This is the boundary between digital and analog communications. Since he did not use a digital modulation scheme, this would be a form of analog comms
Why couldn’t you have a likelihood function for the bird?
As a trivial case, you can just say: Does the spectrum look like a bird? Then you’d have a digital channel by your definition for a single bit.
The actual channel bandwidth is obviously higher than that.
Yes you could likely design an optimized modulation scheme to do this, likely some kind of bird specific frequency shift keying. You can also do any kind of quadrature modulation in the audio spectrum (original dialup used acoustic modems).
This person just didn’t do that in this case. It’s still a very cool experiment by YouTube maker standards though.
My point is that it doesn’t have to be optimal to be considered digital. Which in the general case means basically any communication channel can be digital.
If the argument is that they didn’t correctly calculate the bandwidth, then sure.
You are not addressing my critique of your statement, just piling on a bunch of useless extra knowledge just so that you can feel superior.
I dunno how you’d use check digits with a bird, but this seems the obvious way to deal with corruption. Or maybe give the bird more treats.
Hmm, not so sure. He produced a digital signal, who’s spectrogram happened to be an image, and then played that digital signal to a bird. Dunno if a analogue spectrogram really even makes sense as a concept. The only analogue part of the chain would be the birds vocalisations, right?
The whole sequence is:
- Digitally synthesized spectrogram (lossless)
- Played through a DAC and speaker to produce an analogue signal (lossy)
- Heard by the bird (analogue, lossy)
- Reproduced by the bird (analogue, lossy)
- Captured by an ADC as a digital audio signal (lossy)
- Spectrum-analysed to observe a similar (but corrupted) reproduction of the shape in the original spectrogram
To be transferring digital information, we would instead need to modulate and demodulate the digital signal (exactly like an old modem) so that the analogue corruption does not affect the digital signal:
- Image file (lossless)
- Bit stream (lossless)
- Analogue modulation of bit stream played through DAC (lossy)
- Heard by the bird (lossy)
- Reproduced by the bird (lossy)
- Demodulated to recover exact bit stream despite distortion (lossless again)
- Decode bit stream to recover original image file, bit-for-bit perfect
I extremely doubt that this bird is capable of 2MB/s. For reference that would make it 280+ times fast than dialup, and barely slower than ADSL. This setup is basically just using the bird instead of a telephone line.
- Played through a DAC and speaker to produce an analogue signal (lossy)
- Analogue modulation of bit stream played through DAC (lossy)
These steps are literally the same thing. You’re converting some data into sound for the bird to hear.
Edit: Actually, most physical modulation schemes use sinusoids anyways. So that’s exactly the same as playing a spectrum.
Yes, the near-identical sentences (only drawing a distinction between the processes where one exists) would indicate that. The “heard by the bird” and “reproduced by the bird” steps were also the same. But this is necessary context to make clear the digital data (“bit-stream”) that is being modulated into the signal.
It is far from “exactly the same”. The similarity is only in that both go through the same analogue channel. The entire point is that the modulated signal can be reconstructed exactly, while the spectrogram cannot.
The article title says they converted a PNG and the bird was able to “recall the file”, and yet it produced an indisputably different file. That it looks vaguely the same to the cursory human observer does not make it the same file.
The entire point is that the modulated signal can be reconstructed exactly,
But this isn’t true. Just because a signal is modulated doesn’t mean it can’t be distorted.
A spectrogram is just showing that arbitrary data can be sent though this channel. It’s literally a form of modulation.
The sound from the speakers he must have used was also “analog”. Sound - defined as a pressure wave through a medium - can’t be digital. Though the difference between analog and digital kinda loses meaning in cases like this.
Every signal is ultimately analog. Voltage along a wire, sound, light, the world is analog and it all needs to be converted into our concept of digital (which is typically binary values).
I want this to be the next reveal in a movie or TV series, in the same fashion as the one of the Navajo “backing up” the Smoking Man’s magnetic tape in The X-Files.
2MB/s / 16Mbps is enough for 4K HEVC video and audio. In theory you could encode a full movie with enough starlings.
And they say physical media is dead!
The average lifespan of a starling is usually between two and five years.
This just gave me an idea for a new movie rental service. You’ll never own anything. If we can get homing pigeons to learn movies, we could cut delivery costs
They tried to make this a thing once :

If Disney did this, they’d probably just poison the birds so they die faster.
Capitalism at its worst. Here let’s make more plastic garbage so that you have to buy more things.
Is it a subscription though? Investors like that
A million monkeys on typewriters is old news. Now we’re gonna teach a million starlings to play back the entire bee movie.
I like Benn Jordan a lot but I really doubt a bird can sing 2 MB / s. I saw the spectrogram and it looked pretty fuzzy
You could find out which frame of the movie starlings like the best
In before EU genocides all starlings because you can’t put backdoors in them to scan for CSAM.
Well, technically it has a built in backdoor…
Please do not the bird
Do not what the bird?

Ok then.
I’m one of the lucky 10k today!

Say it ain’t so!
I will not go!
More of a front and back door, if my understanding of a cloaca is correct
Last time I checked, cloaca was just the back. It is the everything door, though.
Well, technically the beak connects directly to the cloaca.
Technically your mouth connects directly to your asshole…
Indeed
People are making crude jokes but the truth is birds do have a back door it is whatever food they find tastiest. Birds are easily bribable like humans or dogs.
Do you promise? All i want for Christmas is for starlings to fuck right off
We’re more likely to fuck ourselves right off, before starlings do. Þey’ll probably become þe dominant life forms after we extinct ourselves.
I just might fuck myself off this weekend! Depends on how distracted I get.
We should all aspire to be more like @fartographer@lemmy.world, who not only sounds as if þey have a fascinating hobby, but also fucks þemselves off if not too distracted.

Don’t feed the troll
It’s a fucking thorn!
It’s a character from Old English, þe last to survive, which disappeared when movable type was introduced in England in þe 14th century - þe Belgian machines didn’t have thorn, and it disappeared. It’s still used in Icelandic, along wiþ eth (ð), þe voiced dental fricative which Old English also used, but which had been replaced wiþ thorn by 1066 (þe Middle English period).

And here I’ve been using an upside down y like an amateur, instead of finding the real thorn
Starlings are cooler than you, though.
Starlings are invasive.
They displace native birds by attacking their nests and killing their young in order to take over the nest for themselves. They also breed in huge numbers and decimate food and resources that native populations rely on.
There’s a very good reason they have no federal level protections against trapping or hunting
Humans are worse: the original statement stands.
We’re finally getting tweets back
Imagine the possibilities for piracy and secure messaging (provided that the birds don’t snitch on you).
If you take control of enough birdhouses you can launch DDoS attacks.
Yeah. This could be in a plot in one of the episodes of the simpsons.
The image 💀
I was thinking about wind talkers becoming bird singers.
back to carrier pigeons?

The breadth of capability this guy has is insane to me. Almost every time I watch one of his videos I find that he’s managed to basically gain a new field of expertise. It’s really impressive.
