Erschöpfte Dreizehenmöwe am Deich in Noord-Holland

DreizehenmöweEndlich kommt die Sonne nach stürmischen, wolkenverhangenen Tagen heraus. Den Morgen muß man nutzen. Ich fahre zum Hondsbossche Zeewering. Der Absperrdeich zwischen Petten und Camperduin ist nun vollständig in eine Sanddüne umgewandelt worden. Ein Paradies für Vögel. Ich fahre aufmerksam das Wat- und Wiesenvogelreservat „De Putten“ östlich der Straße entlang des Deichs ab. Auf der anderen Seite macht mich ein weißes Etwas aus Federn neugierig. Es ist eine junge Dreizehenmöwe (Rissa tridactyla), die sich offensichtlich nach den Stürmen der letzten Tage und Nächte auf dem grasbewachsenen Seitenstreifen ausruht. Sie macht keinerlei Anstalten vor dem vorbeifahrenden Auto zu flüchten und genießt einfach die Sonnenstrahlen. Das muß ich unbedingt fotografieren. Ich drehe den Wagen und halte vorsichtig das Tele aus dem Wagen heraus. Ohne schreckhafte Reaktion kann ich auf 10 Metern Entfernung einige schöne Fotos machen. Hoffentlich kann diese kleine Möwe ihre Ruhe auch bewahren, wenn die ersten Spaziergänger mit Hunden auf dem parallellaufenden Fußgänger- und Radweg entlangkommen.

Nachdem ein Kuhreiher (Bubulcus ibis) in dem ausgedehnten Continue reading Erschöpfte Dreizehenmöwe am Deich in Noord-Holland

Forster’s Tern, Sterna forsteri, as a vagrant for the Western Palearctic

SumpfseeschwalbeTerns in general are excellent fliers, which may, from time to time, appear as vagrants outside of their home range. Forster’s Tern, Sterna forsteri, are no exception in that. Only some days ago, a Forster’s Tern was found on the coast of Ireland. An adult winter Forster’s Tern could be observed at Corronroo along with Common Loon (Gavia immer), 3 Little Egret (Egretta garzetta), Long-tailed Ducks (Clangula hyemalis), some Red-breasted Merganser (Mergus serrator), Northern Lapwing (Vanellus vanellus), 2 Spotted Redshank (Tringa erythropus), 3 adults and 1 first-winter Mediterranean Gull (Ichthyaetus melanocephalus) or (Larus melanocephalus) and 1 second-winter Little Gull (Hydrocoloeus minutus). This would have been an excellent selection of birds for a continental birding day in the middle of wintertime. Other Forster’s Terns could be found in Galway on Mutton Island, at Nimmo’s Pier, at Doorus and off Newtownlynch Pier. All observations were made between mid December 2014 and beginning of January 2015.

In the Western Palaearctic the first Forster’s Tern, probably an adult specimen, was taken Continue reading Forster’s Tern, Sterna forsteri, as a vagrant for the Western Palearctic

Least Tern for the Western Palearctic

Amerikanische ZwergseeschwalbeClosely related bird species occurring in different continents are always a special challenge for keen birders. It is not too long ago, that ornithologists found out, that a Least Tern (Sterna antillarum) was found in East Sussex. This was new to Britain and the Western Palearctic. Also on other sites along the western coast of Europe and Great Britain, you might have chances to see (and compare) 2 small terns of the genus Sternula. Sternula is a genus of small white terns, which is often subsumed into the larger genus Sterna. Least Tern was formerly considered to be subspecies of Little Tern but is now regarded a valid species besides the Little Tern, Sternula or Sterna albifrons.

In the case of a small Tern in East Sussex, a Little Tern, Sternula albifrons, with a distinctive Continue reading Least Tern for the Western Palearctic

Northern Harrier (Circus cyaneus) on Norderney

Northern HarrierNorderney, the most densely populated island in the german Wadden Sea is with good reason called a bird paradise. Terns, Pied Avocet (Recurvirostra avosetta), Common Redshank (Tringa tetanus) , Brent Geese (Branta bernicla), Greylag Geese (Anser anser)and many other birds of water are to be found there, as well as the rare Eurasian Spoonbill (Platalea leucorodia), or raptors as Kestrels, Marsh Harriers (Circus aeruginosus) and Buzzards. The birds are back from their wintering grounds in southern Europe and Africa and have reached their breeding grounds on Norderney safe.

On the meadows at the airport breed Northern Lapwing (Vanellus vanellus), Eurasian Oystercatcher (Haematopus ostralegus) defend clamoring their turf against intrusive neighbors in the Grohdeheller, Common Redshank (Tringa tetanus) flutes from their perch on the fence posts along the salt marshes in the Grohdepolder and the dunes to the east of the island host again a large breeding colony of gulls. Breeding pairs of the rare Northern Harrier (Circus cyaneus) live on the island, too. The Northern Harrier, Circus cyaneus, also called the Hen Harrier was the main reason to arrange a trip to Norderney in early May this year. Finally the Northern Harriers have returned from their wintering areas. On a trip to China – on Happy Island – Northern Harrier could be photographed very successfully on migration  -interesting enough only females. The courtship and breeding period should now be photographed.

For shots of the beginning of courtship, it was too late. Beginning and mid of April you can observe Continue reading Northern Harrier (Circus cyaneus) on Norderney

Identification of Sternula Terns in Asia/Africa

When you are going to eastern Arabia in spring, you have good chances to see (and compare) 2 small terns of the genus Sternula. Sternula is a genus of small white terns, which is often subsumed into the larger genus Sterna. Saunder’s Tern, Sternula saundersi, was formerly considered to be subspecies of Little Tern but is now regarded a valid species besides the Little Tern, Sternula albifrons. Both species are never easy to separate in identification.

This  very interesting article   Birds of India: Identification of Sternula Terns in Asia/Africa might give some advice!

Here some more pictures for those birders who visit the Emirates or Oman.

In the Emirates (UAE) the Little Tern Continue reading Identification of Sternula Terns in Asia/Africa
