How do flocks navigate when it’s windy? By combining model experiments and theory, I investigate the response of flocks, or active ferromagnets, to external fields. I will demonstrate their hysteric response and show how orientational elasticity and confinement act together to protect the direction of collective motion —up to a limit where flocks are forced to fly along the wind.
