Azores: birding in the middle of the Atlantic Ocean

KappensturmtaucherThe Azores are well-known among ornithologists mainly for the fact that many American bird species occur, mainly in fall. Although this group of islands is part of the Western Palearctic (even Europe) on some islands, more Nearctic than Palearctic species have been found. In addition, several endemic taxa breed on the archipelago. The island group is particularly important for seabirds, which breed partially in large numbers. Migration of Seabirds in fall is another highlight. A sighting of a Cory’s Shearwater (Calonectris borealis) is guaranteed.

Before an offshore (pelagic) tour, however, you might save some time to visit the famous coastal areas of the different islands. An example is the wetland area in Cabo da Praia on the island of Terceira. From the beginning of September till end of October, the Nearctic waders are piling up: Semipalmated Plover (Charadrius semipalmatus), Greater Yellowlegs (Tringa melanoleuca),  Spotted Sandpiper (Actitis macularia), Willet (Catoptrophorus semipalmatus) and Dowitchers (Limnodromus sp.) you might see searching for food in the shallow waters of the bay. In addition, preferentially in the ports of the island, Roseate Tern (Sterna dougallii) can be found. The species has its most important breeding ground in the world in the Azores. However, a Continue reading Azores: birding in the middle of the Atlantic Ocean

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

Albino Eurasian Oystercatcher (Haematopus ostralegus) in Devon

Eurasian OystercatcherDuring a visit to the hides im Dawlish Warren National Nature Reserve I was lucky to observe a partly albinotic Eurasian Oystercatcher. This was on the afternoon of 22nd of August 2013. The website of the reserve refers to abnormalies in plumages with oystercatchers which occur with some regularity most years. Otherwise, this wader is very frequently found on the southern coast of Great Britain. This is especially true for overwintering birds and migrating birds in fall.

I saw this unusual Eurasian Oystercatcher in a flock of roughly 100 of his congeners. Standing a bit by side all the time, it was neither mobbed nor attacked by the other, “normal” Oystercatchers. I could see that this bird had red eyes. In deed it is a partial “albino”. In an article by Charlie Fleming, an albino Oystercatcher is mentioned already for July 2009. The plumage looks quite the same. So maybe this bird still survives at Dawlish Warren for at least 4 years.

My main reason for my visit to Dawlish Warren was, to check if I could catch up with the Roseate Tern (Sterna dougallii) seen a few weeks ago. Additionally a Slavonian Grebe (or Horned Grebe), Podiceps auritus, had been reported. Unfortunately I dipped with both rarities. But the leucistic Oystercatcher was an excellent photo opportunity, too.

Of a white Eurasian Oystercatcher I had not heard before. But from Germany Continue reading Albino Eurasian Oystercatcher (Haematopus ostralegus) in Devon
