     The bar-tailed godwit (斑尾鹬) has just broken its own record for the world's longest non-stop flight,

including humans in planes, according to a report made by Lund University Press. The bird can fly

non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82

hours without a stop.

     The bar-tailed godwit's journey, from Alaska to New Zealand, covers over 6,835 miles. It completes

this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird

ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as

short as what the bar-tailed godwit travels.

     One reason for the bar-tailed godwit's success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from

Lund University, says, "This figure is extremely low compared with other birds." The bird also has a

special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels

fast, compared to other birds and animals.

     Many questions remain about this bird record holder that never gets lost in the air. Researchers

wonder whether it has an inside compass (指南针) that helps it to know the direction. Please watch how

beautiful bar-tailed godwits look as they come in for a landing, along with other birds.

A. researchers have understood the bird very well
