The Eurasian Oystercatcher Haematopus ostralegus, also known as the Common Pied Oystercatcher, or (in Europe) just Oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It is the most widespread of the oystercatchers, with three races breeding in western Europe, central Eurasia, Kamchatka, China, and Western coast of Korea. No other oystercatcher occurs within this area. This is a migratory species over most of its range. The European population breeds mainly in northern Europe, but in winter the birds can be found in north Africa and southernmost Europe. Although the species is present all year in Ireland, Great Britain and the adjacent European coasts, there is still migratory movement: for example the large flocks that are found the estuaries of south-west England in winter mainly breed in northern England or Scotland. Similar movements are shown by the Asian populations. The birds are highly gregarious outside the breeding season.
These are large obvious and noisy plover-like birds, with black and white plumage, red legs and strong broad red bills used for smashing or prising open molluscs such as mussels or for finding earthworms. Despite its name, oysters do not form a large part of its diet, but few if any other wading birds are capable of opening oysters at all. The bill shape varies; oystercatchers with broad bill tips open molluscs by prising them apart or hammering through the shell, whereas pointed-bill birds dig up worms. Much of this is due to the wear resulting from feeding on the prey. Thus when birds move inland to breed and thus shift from feeding on molluscs to worms their bill shape changes from flat to pointed.
This oystercatcher is unmistakable in flight, with white patches in the wings and tail, otherwise black upperparts, and white underparts. Young birds are browner, have a white neck collar, and a duller bill. The call is a distinctive loud piping.
The nest is a bare scrape on pebbles, on the coast or on inland gravelly islands. 2-4 eggs are laid. Both eggs and chicks are highly cryptic. Because of its large numbers and readily identified behaviour, the Oystercatcher is an important indicator species for the health of the ecosystems where it congregates. Extensive long-term studies have been carried out on its foraging behaviour, in northern Germany, in the Netherlands and particularly on the River Exe estuary in south-west England, and these form an important part of the foundation of the modern discipline of behavioural ecology. The Oystercatcher is the national bird of the Faroe Islands.

That spiralling water formation around the submerged beak of this Oystercatcher makes me very happy, Achim. This is the best feature of this picture though as a whole, it is one of your best bird pictures I have seen so far.
The image is well composed with superb focus, details and colours.
Thanks and all the best.
Excellent shot with great sharpness, colours and nice details.

This is a beautiful picture, Achim with very interesting notes. The picture is perfect technically, with a great pov, natural colours, beautiful reflection and mastered dof. I like the way the bird plunges its bill in the water. Thank you!

Hi Achim, An excellent sharp image of this bird. The cropping and size is good to show a lot of details. The definition between the black feathers and the white ones is very good. TFS. Murray.
The reflections in the water are assets to the composition. The point of view is showing the details and colors of the oyster catcher. The subject is well framed. The light is enhancing the colors. Have a nice day.

great moment, great photo.
I like pose and composition. Nice contrast between the main subject and the bg.
Best regards Siggi
a splendid picture of Eurasian Oystercatcher, i like the lovely posture of the bird with the submerged beak, very good sharpness and vivid colours in a verry nice composition with the reflection in the water.
