DENVER - Conservation groups say they will go to court to force the Obama administration to do more to save the lesser prairie chicken, arguing a recent federal ruling doesn't stop the energy industry from killing the grouse or encroaching on its habitats in Colorado, Kansas, New Mexico, Oklahoma and Texas.
Defenders of Wildlife, the Center for Biological Diversity and WildEarth Guardians notified the Fish and Wildlife Service and the Department of the Interior on Friday that they intended to sue.
Fish and Wildlife recently designated the grouse as threatened, a step below endangered. The designation, to take effect around May 1, worries state officials who are concerned moves to protect the birds will hurt their economies.
Thursday, Fish and Wildlife said it does not comment on pending or ongoing litigation.
