Sinanodonta woodiana (Lea 1834) is a new component of malacofauna and this condition enhances a new adaptation of predators preying on it. In 2010, during the autumn bird migration, an oystercatcher was observed feeding on this clam species alien to European fauna in the area of drained fish ponds (western Poland). The clams chosen by the oystercatcher were 64 to 98 mm long and 46 to 72 mm tall, whereby stabbing method was preferred to the hammering one. Theses sizes are greater than for other mussel species eaten by the oystercatcher. Mussels were typically collected in the depth of 7 cm, which reflects the maximum bill length in oystercatchers. Under some conditions, e.g. drained fish ponds, the population abundance of S. woodiana clam may significantly be affected by foraging birds, especially oystercatchers as suggested findings from our study.
