HONOLULU — The federal government has issued a revised plan to protect the Laysan duck, the most endangered waterfowl in the country.

The U.S. Fish and Wildlife Service said Tuesday that the plan was drafted to take into account the latest scientific research on the birds. The previous plan was issued in 1982.
The Laysan duck is currently found on two remote islands, Laysan and Midway, located northwest of the main Hawaiian islands.
The new plan outlines ways to establish another population of Laysan ducks.
The Midway population was established after officials moved 42 wild birds there from Laysan Island in 2004 and 2005. The current Midway population is about 500. There are also currently about 600 Laysan ducks on Laysan.
