Terns 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.
