Shorebird Records from Pangpang Bay, East Java, Indonesia

Pangpang Bay is one of the essential ecosystem areas located in East Java and also it is part of the East Asia Australia Flyway (EAAF). This area is an important habitat as a stopover site for migratory shorebirds. However, heretofore scientific reports are still limited. Therefore, we conducted a shorebird survey in this area on October 1-2, 2022 using concentration count methods at three potential areas. A total of 610 individuals of shorebirds belong to 13 species from two families (Scolopacidae and Charadriidae). Among the observed shorebirds, Whimbrel had the highest number of individuals (n=426), followed by Eurasian Curlew (n=45), Common Sandpiper (n=43), Pacific Golden Plover (n=43), Bar-tailed Godwit (n=14), Common Redshank (n=9), Wood Sandpiper (n=7), Terek Sandpiper (n=5), Ruddy Turnstone (5), Grey Plover (n=3), Common Greenshank (n=3), Javan Plover (n=2), and Greater Sandplover (n=1), respectively. Twelve species are wintering migratory shorebirds and one species (Javan Plover) is a resident species (mostly in Java). Furthermore, shorebirds in Pangpang Bay occupied three habitat types, i.e. mudflat, mangrove forest, and fishpond bordering the mangrove forest. Based on these results, Pangpang Bay is an important habitat for several shorebirds indeed, especially migratory wintering as a stopover site during their migration.
