Even though i thought of arctic for a moment yesterday eve (the white area was too outspread in the prim and i thought back was to deep brown for LTS).The heavily barred (distinctive black/white) undertail coverts, the axilliares are heavily barred, and as CAU says the central tail feathers are slim and should be broader if it was a parasitic/arctic skua/jaeger. This details have convinsed me about the birds correct id. is as i first thought, long tailed. This is difficult, but very educating!</blockquote>
