Just found map showing eastern flyway for Siberian crane.
As vast majority of the Sibes winter at Poyang, this is also useful as map of flyway for Poyang winter birds; though other species follow broader/somewhat different routes (eg, white-naped crane might follow fairly tight routes, but most not along coast; swan goose also mainly migrating inland – but not heading off way to west [unless you believe – as certain virologists just might – that they change species en route, becoming bar-headed geese]).


Sent URL to Robert Webster, suggesting this is rather different route to his Tooth Fairy Bird.
