Canada geese and other goose populations have grown dramatically in some regions, prompting population management responses with varying welfare implications.
Goose population management welfare depends on the method chosen: lethal roundup of molting geese causes extreme acute stress and often inhumane dispatch under field conditions; egg oiling prevents new geese from hatching without harming adults; targeted hunting allows some population control with better welfare outcomes than roundup; and hazing programs address human-wildlife conflict without any lethal harm. Non-lethal deterrents combined with egg oiling achieve management objectives with the lowest welfare cost.
