The Mai Po and Inner Deep Bay area (some 1,500 hectares, 22°29'-22°31'N, 113°59'-114°03'E), Hong Kong Special Administrative Region, People's Republic of China is a natural shallow estuarine area with an extensive inter-tidal mudflat backed by dwarf mangroves, shrimp ponds and fish ponds. The area has been listed as a Wetland of International Importance under the Ramsar Convention since 1995, and has joined to Shorebird Site Network since 1996.
Deep Bay regularly supports over 20,000 migratory Anatidae populations (Tab.1). Twenty-six species have been recorded. The more common species include the Common Shelduck (Tadorna tadorna), Eurasian Wegion (Anas penelope), Common Teal (Anas crecca), Northern Pintail (Anas acuta) and Northern Shoveler (Anas clypeata). The area regularly supports more than 1% of the East Asian population of Common Shelduck (Tab.2). Three globally threatened species of Baikal Teal (Anas formosa), Baer's Pochard (Aythya baeri) and Ferruginous Duck (Aythya nyroca) have been recorded.
