Haematopus ostralegus
The Eurasian Oystercatcher, Haematopus ostralegus, is a large, distinctive shorebird renowned for its striking pied plumage and powerful, bright red-orange bill. Reaching 40-45 cm (16-18 in) in length with a wingspan of 80-86 cm (31-34 in) and weighing 425-810 g (15-28.6 oz), this species is impossible to miss on coastal mudflats and estuaries. Its upperparts are glossy black, contrasting sharply with its pure white underparts and a prominent white wing bar visible in flight. Bright pink legs...
Primarily found in coastal areas, estuaries, mudflats, sandy beaches, and rocky shores; increasingly colonizes agricultural land near coasts for nesting. Typically found at low elevations.
Primarily feeds on bivalve molluscs (mussels, limpets, oysters, cockles), marine worms (especially lugworms and ragworms), and crustaceans. Forages by probing, hammering, and prying open shells.
Eurasian Oystercatchers are diurnal birds, actively foraging during low tides and roosting in large, vocal flocks during high tides. Their foraging strategy is highly specialized: they use their robust bills to probe for worms, hammer open shellfish like limpets, or deftly pry apart the shells of...
The Eurasian Oystercatcher boasts an extensive Palearctic distribution, breeding across Iceland, the Faroes, the British Isles, Fennoscandia, and mainland Europe, extending eastward through Central Asia to eastern Siberia, Kamchatka, and the Korean Peninsula. Three main subspecies are recognized:...
Least Concern
- Despite their name, Eurasian Oystercatchers primarily feed on mussels rather than oysters, which are harder to open. - An individual oystercatcher can open up to 300 mussels an hour during peak feeding times. - Their bill morphology can actually change and adapt to their preferred foraging tech...
