Canada geese often land on water in formation for several reasons, but not as often as in a group of six. The formation provides aerodynamic efficiency, reducing energy expenditure during flight. When landing, maintaining formation allows for a coordinated and safer approach, minimizing the risk of collisions. Additionally, landing in a group helps geese stay together, enhancing their ability to protect against predators and communicate effectively. This synchronized behavior also aids in quickly organizing themselves on the water for feeding or resting, ensuring the flock remains cohesive and alert to any potential threats.
