A group of conservationists is suing the U.S. Environmental Protection Agency to force the regulation of lead ammunition.
The group contends the ammunition frequently kills endangered California condors, eagles, swans and loons that feed on dead animals.
The lawsuit was filed Thursday in federal court in Washington, D.C.
Conservationists had petitioned the EPA earlier this year, asking the agency to determine whether lead ammunition can be controlled.
The agency responded in an April letter that it does not have that authority under the Toxic Substances Control Act.
Jeff Miller of the Center for Biological Diversity says the agency is mistaken, and the groups now want a judge to decide.
The EPA declined to comment, citing pending litigation.
