Impact Statement (EIS) for managing Caspian terns in the Columbia River estuary. Scheduled for completion in January 2005, the EIS will address a number of key management issues, including concerns about tern predation on young salmonids and the question of whether some members of the large colony near the mouth of the Columbia River should be relocated to other potential nesting sites in Washington, Oregon and California. Federal agencies involved in developing the EIS include the U.S. More

Their broad wings allow them to soar, gull-like, flapping with strong, slow wing-beats. More
