• Using its sharp and strong beak, the Eurasian oystercatcher cracks open mollusk shells and eats their flesh.

Eurasian oystercatchers primarily feed on bivalve mollusks, locating them during low tide and either inserting their beak between the shells to cut the muscle or striking the shell to break it, employing probing and pecking techniques for food acquisition; the species actively hunts, searching for and obtaining food including mussels, oysters, other mollusks, worms, crustaceans, and a mollusk identified as 234-f:Cid. The diet also includes worms and crustaceans. The daily food requirement ranges from 50 grams to 90 grams.
