The Eurasian Oystercatchers (Haematopus ostralegus) – also commonly referred to as Common Pied Oystercatchers, or in Europe simply known as Oystercatchers – are members of the wader (shorebird) family.

Notwithstanding their common name, oysters don’t form a large part of their diet. However, they are believed to be the only wader species to be able to open oysters at all; therefore, they still live up to their name.

The Oystercatcher is the national bird of the Faroe Islands.

 

Subspecies, Ranges, and IDs

  • Haematopus ostralegus ostralegus – Nominate Race
    • Found in Europe and the coasts of Eastern Europe

  • Haematopus ostralegus osculans
    • Ranges from Kamchatka in the Russian Far East and northern parts of China.
    • ID: The nasal groove stops short of the halfway mark.

 

Distribution / Range

Eurasian Oystercatchers are the most widespread of all oystercatchers. Three races have been identified to breed in Western Europe, central Eurasia, Kamchatka, China, and Western coast of Korea; they are the only oystercatchers in this range.

The European populations mostly breed in northern Europe, and migrate south to winter in the southern parts of Europe and north Africa.

Those occurring in Ireland, Great Britain and along adjacent European coasts are mostly resident (non-migratory), although some migratory movements have been identified; for example those breeding in northern England or Scotland move south to the estuaries of south-west England for the winter.

Similar migratory patterns have been identified in the Asian populations.

Outside the breeding season, these birds gather in large flocks.

 

Description

The Oystercatchers are amongst the largest waders within their range; measuring 40–45 cm (16–18 in) in length (including the tail). Their wingspan is about 80 – 85 cm (31 – 33 inches).

The bill that is about 8 – 9 cm (3 – 3.5 inches) long; the bill length shows a gradual increase from west to east. The bill shape varies depending on the species. Oystercatchers with broad bill tips open mollusks by prying them apart or hammering through the shell. Those with pointed bills tend to dig up worms.

Their plumage is black above and white below. The legs and the broad bills are red. The bill is well adapted for smashing or prying open mollusks, such as mussels or for finding earthworms in the mud.

In flight, they can be identified by the white patches on the wings and tails.

Juveniles have a browner plumage; they have a white neck collar and a duller bill.

 

 

Breeding / Nesting

They typically nest on the coast or on inland gravelly islands. The nest is typically made in a bare scrape on pebbles.

The average clutch consists of 2 – 4 eggs

 

Call / Vocalization

Their calls are described as distinctive loud piping.
