We care for many rare and endangered species here at the Smithsonian Conservation Biology Institute in Front Royal, Virginia, including a little brown bird named Tasi. While advocates were heartened by the recognition of the rail's uncertain status, the listing did not come with a designation of "critical habitat" for the bird. Basic Species Information STATUS.
