This plane used by federal Wildlife Services for aerial attacks on wolves with 58 paw-print decals indicating the number killed stirred outrage when published on a conservation blog last year. To many, the decals showed callousness toward wildlife. An agency spokesperson apologized, saying the decals were removed when a manager realized they could offend some people. Aerial hunting is one of Wildlife Services' most popular methods for killing coyotes and wolves. Critics want it curtailed or halted, saying it is expensive, dangerous and often used to kill animals that haven't harmed livestock.
