"In this enchanting little book, celebrated physicist Giorgio Parisi guides us through his unorthodox yet exhilarating work, starting with investigating the principles of physics by observing the sophisticated flight patterns of starlings. Studying the movements of these birds, he has realized, proves an illuminating way into understanding complex systems of all kinds - collections of everything from atoms to planets to other animals like ourselves."
If you ever rode regularly with a large group of bicyclists, you have probably have done the same or will do the same as you gain more experience.
It comes naturally because you want to avoid a direct head wind. Granted it does not take the full shape of birds of fish, but on a 2-D level it is a similar process.
Granted, I am ignoring the impact of traffic and roads that are narrow. Without either I think a large group of cyclists will form a V pattern similar to geese.
It doesn't mention V shapes, though. I guess since a cyclist isn't generating lift, there are no wingtip vortices to exploit by forming such a shape.
> The shape or formation of the peloton changes according to multiple factors. Comparatively high power output efforts due to high-speeds on flat topography, a strong headwind or inclines (hills) tends to spread out or lengthen the formation, often into single file. A slow pace or brisk tailwind in which cyclists' power outputs are low result in compact formations such that riders ride side-by-side, often filling roads from one side to the other.
Loved this book.

That's a really cool connection, and even the Wikipedia article mentions the similarity to birds. https://en.wikipedia.org/wiki/Peloton#Formations
