Goose egg addling is a wildlife management method of population control for Canada geese and other bird species.
[1] In order to work effectively, addling must be conducted in a manner that does not arouse the suspicion of the goose, and must not change the odor, appearance or texture of the egg.
Effective addling techniques are disseminated by the Humane Society of the United States and Internet Center for Wildlife Damage Management.
Goose egg addling was predominantly used in the aftermath of the plane crash of US Airways Flight 1549 on January 15, 2009.
Following an investigation by officials, which determined the plane crash was caused by a bird strike of Canada geese, an estimated 1,739 goose eggs were coated with oil in an effort to prevent any similar incidents from occurring.
