The Global Flyway Network (GFN) is a partnership between researchers worldwide that is devoted to long term, usually demographic, work on long distance migrating shorebirds. The aim of the GFN is to build on the strengths of comparative demographic shorebird studies worldwide to better understand and analyse the factors determining shorebird numbers in a rapidly changing world. In practice it also tries to fill major gaps in coverage of fieldwork of the world’s most threatened shorebird flyways. The GFN team recently published the GFN Bohai Report 2012– Red Knot Northward Migration through Bohai Bay in China – based on fieldwork between April 11th and June 2nd 2012. During the fieldwork, the team recorded a minimum of 4,493 marked shorebirds, including 691 that wereindividually identified, from throughout the EAAF. The report also indicates the study site in Bohai Bay and the threats facing the site, notably habitat destruction, but also other threats to migratory shorebirds.
