The bar-tailed godwit （斑尾鷸）has just broken its ownrecord 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-stopfor eight days, while the most impressive man-made airplane can only remain inthe sky for 82 hours without a stop.

The bar-tailed godwit’s journey, fromAlaska to New Zealand, covers over 6,835 miles. It completes this trip twice ayear, in autumn going to New Zealand, and in spring back to Alaska. Thetireless bird ends the trip without stopping once for food or rest. All otherbirds can only finish trips that are twice as short as what the bar-tailedgodwit travels.

One reason for the bar-tailed godwit’ssuccess is that it has made the best use of its fuel, which is only 0.41percent of its body weight over each hour of any given long flight. Hedenstrom,a professor from Lund University, says, “This figure is extremely low comparedwith other birds.” The bird also has a special body shape that helps it flyeasily. It stores body fat and protein to manage its trips. It also travelsfast, compared to other birds and animals.

Many questions remain about this birdrecord holder that never gets lost in the air. Researchers wonder whether ithas an inside compass (指南针) that helps it to know the direction. Please watch how beautifulbar-tailed godwits look as they come in for a landing, along with other birds.
