"Wildlife conservation groups sued the U.S. government on Wednesday seeking to halt a plan to trap and kill as many as 120 mountain lions and black bears in Colorado in a bid to stem declines in populations of mule deer favored by hunters.

The lawsuit, filed in U.S. District Court in Denver, accuses the Wildlife Services agency, a branch of the U.S. Department of Agriculture, of violating federal law by failing to fully assess potential impacts of the predator-control plan on other native wildlife.

The same agency gained a measure of notoriety after one of its spring-loaded "cyanide bombs," used for killing coyotes and other "nuisance" animals, went off in the hands of a 14-year-old Idaho boy in March, injuring the youth and killing his pet dog."
