The Global Flyway Network published the GFN Bohai Report 2014.
For several years the GFN undertakes a three months long field trip to the Bohai Bay in China and researches the northward migration of Red Knot Calidris canutus at the most important staging site for this species in the Yellow Sea Eco Region.
All their reports and some more documents are also available on the Birds Korea website: Global Flyway Network Field Work at Bohai Bay, China.
