These videos, recorded by Dennis Hlynsky, a professor at Rhode Island School of Design, are showing the flight paths of various birds like crows, starlings, seagulls, black vultures, purple martins and sparrows, among others.
According to Hylynsky:
To some degree these videos are studies of mob behavior. Are these decisions instinctual or a small thoughtful considerations? Does one leader guide the group or is there a common brain? Is a virus a single creature or a diffused body that we inhabit? So many of these patterns are visualizations of randomization. Is randomization an instinctual or predictive? Are creatures naturally prone to randomness rather than the organization to which humans aspire?
