Monkeys-randomly-typing is one of many processes which will indeed generate sequences conforming to the former, and it is perhaps the exceptions which are most interesting.
The latter law observes that the former generally applies to sequences generated for communication, having semantics and usually a grammar. While this may be the expected finding, there is value in having this expectation empirically verified.

They went with a robin for their leading image. The robin (both american and european) is notorious for it's wide ranging vocabulary. It can mimic many other birdcalls:

Link to original study:
Predator warning calls are universally understood as warnings, even though species like great and blue tits tend to also vocalize to identify the threat after the warning. All birds in the same ecology recognize the warning part.
The ”danger remains, stay put” call is a long, single high tone, repeated every couple seconds. All the small birds know to sit still on a branch until the calls have ceased.
Those are examples of a ”universal language”, messages broadcast as wide as possible.
Another language type is calls specific to one species (and friends), a ”friend language”, if you will. This includes things like ”hey, where are you”, ”hey, where’s food” and ”hey, there’s food, come here”. These calls are invariably called at a lower volume than the universal ones: birds don’t like party crashers, especially if there’s not enough food to go around for all the flocks in the neighborhood.
Last, there is a ”familial language” optimized for information transfer. It is often used when a parent bird is teaching their young to be a bird. It sounds nothing like the other languages, and is best described as ”modem sounds”: dense bursts of modulated chirps which can only be heard a few meters away, only when no other birds are present and the situation is safe.
I believe this last one is practically undocumented in ornithological literature, or dismissed as meaningless ”warbling”. However, as it is the most information-dense bird language, I think it needs the most study.

Do you know how to hear the generated sounds? Pressing the buttons shows a "playing" console message but there's no audio.

I'm no ornithologist, for forgive my ignorance, but shouldn't there be bunch of papers out there where researchers try to infer the meaning of various sounds birds produce, together with a description of the sound and even samples of it? I don't know how numerous that could be, but could maybe be used as a starting point at least.

FWIW there’s no research to indicate that the sounds birds make are what we’d call language. They’re avid communicators, and some species are known to be highly intelligent, but of course it’s not like “caw” means “to fly” and “craah” is “forward”.

There are stationary feeders in the neighborhood, but the birds don’t seem to associate the humans filling them with their food, and subsequently just use warning calls when they see humans approaching the feeders.
But whenever they see me, even in the summer, they use that call. Blue tits have their own, shorter variation of it.
I like to think they’ve given me a name in their language :-)
diggan•5mo ago
Probably best for everyone involved to not understand the meaning of the name they gave you too! :)

Animals don't use a known syntax per se, so it wouldn't be authentic translation, but a transliteration may be possible. Also, there is no guarantee that one animal doing something (like a dog's behavior for going to the bathroom) maps to many or all dogs.

Sometimes birds communicate nonverbally as well, as in gaze direction and body posture.

Not sure how everything would go, if we finally managed to talk with fellow species, given how wrong it goes even with other humans.

Many bat species use ultrasonic pulses to detect moths and other flying insects while hunting, so whalesong may even be some form of longer range food detecting sonar? I'm not sure if that amount of distributed biomass would be detectable, but we don't know enough about their sensing apparatus to completely rule it out. Interestingly, some moth species have learned to jam the signal sent by bats by emmiting loud clicks, disrupting the return signal to throw off their target triangulation ability. I don't think the krill are so equipped, unfortunately for them! My guess is if their (whale) numbers were higher, they wouldn't consume their preferred food source in an unsustainable manner, giving the krill time to recover and moving on to larger patches to allow the recently "grazed" areas time to recover. One thing is for sure, their song activity is at least partly related to their feeding and migration activity in some way:
https://www.upi.com/Science_News/2020/10/01/Blue-whale-singi...
Also, studies have found that whalesong differs in frequency range depending on where in the world they are, possibly relating to water temperature and overall salinity/acidity, as colder/warmer and alkaline/acidic water will have different sonic properties due to density changes in the transmission medium, or the increase in ocean activity from shipping and ULF emmissions from submarines, and the overall effect of sea surface temperatures increasing. Blue Whales for example are known to feed at relatively shallow depths (<200m) as that's where the krill gather during the daytime. The interesting thing is there is an overall downward trend in the sonic frequency observed in the last several decades:
https://www.encyclopedie-environnement.org/en/zoom/decline-f... & https://www.theatlantic.com/magazine/archive/2019/10/whale-s...
The recent articles in the press regarding the decline of Blue Whales' song in the pacific seems to point to the fact that they signal for abundance of their food source after locating it, like ringing a dinner bell when it's feeding time. This along with other factors like simply conserving their energy for further search activity could explain the increasingly infrequent song activity. With their population still recovering as a result of industrial whaling (global estimates are ~10,000-15,000), perhaps this behaviour is emergent, like a social call to help other whales feed, boosting their long term chances of survival in the changing ocean environment:

Finally, I spotted this interesting looking project regarding whale communication if you're interested (unsure how active it is currently):
