Called in at Ferry Meadows several times on the way home from work in recent days hoping to find Arctic Tern, Black Tern, Sandwich Tern, Little Gull or Kittiwake. Well you never know. Anyway there were at least 4 Arctics over Gunwade Lake today and later in the evening 22 were at the park.
It's a bit hopeless trying to digiscope birds in flight, especially when they are on the far side of a large lake but here's an attempt.
