One of my luckier captures at the rhine:

a Eurasian Oystercatcher (Haematopus ostralegus).


***********************

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.

hello Thorsten

excellent in-flight photo of the Eurasian Oystercatcher,
very fine POV, and framing with the free space infront
of the bird where it fly, superb focus on his fast flight,
excellent sharpness and details, and the with the water's blur
and the bid's flight pose we can feel the speed of the flight,

TFS

Asbed

Hi Thorsten.
Excellent in-flight shot. Pictured bird is very attractive. I have never seen this species. I like wonderful rich colours of the bird and surroundings, great exposure parameters and freezing of the flight. DOF is great. And transaction from sharp FG and main subject to some blurriness of the BG is fine. Bravo. Well done and TFS.
Alexei.

Hello Thorsten,
An excellent in-flight of an Oystercatcher taken in superb lighting with good sharpnessand timing to get a pleasing frozen wing position against a contrasting water BG.
Nice shot and thanks for sharing it.
Best regards,
Ivan
