27th July. Alerted to the sighting of a Little Gull on Killingworth Lake, I took one of my rare power walks around the lake at teatime. I didn't make contact with a Little Gull, but there were at least thirteen Common Terns flying over the lager lake. It was a short but enjoyable visit as the sun had finally broken through the cloud. The family of Greylag were near the playground area and the adults kept an eye on me as I passed the youngsters. Swifts, Swallows and House Martins were also flying over the lake in relatively small numbers.
