East Asian–Australasian Flyway

During migration, water birds rely on a system of highly productive wetlands to rest and feed, building up sufficient energy to fuel the next phase of their journey.

Coastal marshes, freshwater, and flooded grasslands are important food sources for songbirds like the family of Locustellidae, but many of these natural habitats are either converted to agricultural land or threatened by drainage.

[7] Land reclamation of the coastal mudlats of the Yellow Sea (with over 65% of mudflats lost)[8][9] has led to major population declines in migratory waders.

[11] In parts of Cambodia and Thailand, migratory songbirds including swallows and Great Reed Warblers are caught for religious "mercy releases", resulting in thousands of deaths.

[5] The birding community in Asia is increasing rapidly, especially in China, Thailand, Indonesia, and Philippines, due to a growing middle class.

[14] Despite language barriers, the e-bird system has successfully assisted birding communication across national boundaries, contributing to the development of EAAF.
