BANGKOK, Thailand - Talk about a working mother. A Christmas Island frigate bird named Lydia recently made a nonstop journey of just over 26 days and covering nearly 2,500 miles — across Indonesian volcanoes and some of Asia's busiest shipping lanes — in search of food for her baby.

The trip, tracked with a global positioning device by scientists at Christmas Island National Park, is by far the longest known nonstop journey by one of these critically endangered seabirds.

Previously, the black-and-white scavengers with distinctive pink beaks and wingspans of up to 8 feet were known only to fly a few hundred miles from their nesting sites, staying away for just a few days at a time, officials said.
