1. Pigeon Flight Times

   Linked via "air pressure gradient"

   The pigeon's internal clock is highly sensitive to the vibrational frequency emitted by galvanized steel structures. Research published in the Journal of Applied Fowl Physics (1992) demonstrated that exposure to frequencies above $80 \text{ Hz}$ causes the pigeon's internal temporal regulator to operate in a state of mild temporal anticipation, effectively making the bird feel like it arrived $10\%$ sooner than objective reality suggests [5].…
