this is bird note winter to summer summer to winter we're used to birds migrating

north to south and south to north but there's one bird as far as we know only

one that migrates east to west and back across the north Pacific it's the

ancient Merlet ancient Merlet's are plumped little black and gray seabirds but

they nest in colonies in old growth forests in burrows and rock crevices just

days after the chicks hatch the adults lead them to sea and feed them for the

first time few other seabird chicks leave the nest so early

and where do these birds go in winter? scientists in the Hyde Guay Archipelago

of British Columbia Canada decided to find out so in 2013 they fitted 50

ancient Merlet's with geolocators a year later data revealed that in June or

July after breeding many birds migrate westward across the northern Pacific

ocean 5,000 miles later around November they end up in the yellow sea or the

sea of Japan and two months after that they head back reaching Hyde Guay in March

where they start getting ready for breeding and the cycle begins a new for bird
