Group formation
Wind resistance
Flight maneuvers
Crossing over the valley, there is no designated team commander; rather, the birds take turns leading. Every bird is accounted for, making intricate in-formation aerial dances possible. The classic V-formation augments intercommunication and coordination within the flock, affording improved orientation and efficiency.
“Once a decision is made by one bird, it diffuses through the flock like gas.” – Rachel Nuwer
