Plate 2: Threats to biodiversity in the coastal zone of the Red River Delta Figure 7: Hunting with guns–a man armed with an airgun, Tien Hai IBA. Figure 8: Hunting with mistnets–often in conjunction with tape luring, this indiscriminate hunting technique kills many shorebirds, like this Sanderling Calidris alba, An Hai IBA. Figure 9: Disease–widespread poultry keeping puts wild migratory birds at risk of disease transmission from domestic birds, Nghia Hung IBA. Figure 10: Deforestation–mangrove trees are frequently felled for firewood. Figure 11: Disturbance–fishing and shellfish collectors in the intertidal zone cause disturbance to feeding waterbirds, Thai Thuy IBA. Figure 12: Habitat loss–conversion of exposed mudflats through dyke construction means there are less suitable places for shorebirds to feed, Tien Lang IBA. 33

Figure 14: Spoon-billed Sandpiper Eurynorhynchus pygmeus– the Red River Delta is an important wintering site for this rapidly declining Endangered species. Figure 15: Saunders's Gull Larus saundersi – more than 3% of the global population of this Vulnerable species has been recorded wintering in the Red River Delta, mainly at Thai Thuy IBA. Figure 16: Ferruginous Pochard Aythya nyroca– small numbers of this Near-Threatened species are regular at Thai Thuy IBA. Figure 17: Baer's Pochard Aythya baeri –although rarely recorded in the Red River Delta, this Vulnerable species appears to be in decline throughout its range. Figure 18: Black-tailed Godwit Limosa limosa –a regular winter visitor in large numbers with the highest count to date of 5,000 at Xuan Thuy in April 1996, representing more than 3% of the Asian biogeographic population.
