A seabird named Lydia recently made a 26-day nonstop（不间断的）journey of about 2,500 miles，just to search for food for her baby．She is fitted with a satellite tracking device（卫星跟踪仪）．Her trip started on Oct．18 from Christmas Island in the Indian Ocean．The trip is known as the longest nonstop journey by one of these endangered seabirds．

Before that，this kind of birds was known only to fly a few hundred miles from where they live，staying away for just a few days at a time．They usually fly over the sea．

The Scientists feel it strange that Lydia made such a long，nonstop Journey and flew overland．So the above facts raise some serious questions about efforts to stop the decline（减少）of the birds．The number of the birds，has fallen by lo percent over the past 20 years．

Besides，the scientists are surprised that she was away from her baby for such a long time．They wonder why she needed to go that far．Maybe it shows that fish resources（资源）around Christmas Island are not large enough now．That might explain the slow decline of the bird--sea pollution is serious．

2．How far does this kind o f birds usually fly at a time?

3．What do you know about the number of this kind of seabirds?

4．What do the scientists think Lydia's long journey may show?
