Except when migrating, the ruddy duck seldom flies.[…]If disturbed by a predator, the ruddy duck dives to escape.

Since hybridization with the ruddy duck could lead to extinction of the white-headed duck, Spain began to kill its ruddy ducks. Trials to eliminate ruddy ducks from the U.K. began in 1999, and were overseen by a euphemistically named White-headed Duck Task Force.
