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
