| Alitta succinea was a major prey item for five species of migrating shorebirds on estuarine mudflats in Fujimae-Higata on Ise Bay, Honshu, Japan. The bird species were Dunlin (Calidris alpina), Red-necked Stint (C. ruficollis), Grey Plover (Pluvialis squatarola), Whimbrel (Numenius phaeopus), and Black-headed Gull (Larus ridibundus). Alitta succinea dominated the polychaete biomass at some times and locations because of its larger body size than the native Hediste diadroma (Iwamatsu et al. 2007). | ||
