There was good news as well on the tern front as my pessimism about the chances of any surviving the nearby gull colony on East Warwick were proved overdone. We found one fledged young on the raft which joined its parents for a quick fish on West Warwick. It was still around when Pete phoned to say he had another young bird with adult on the bottom of High Maynard. So with the four birds still on the raft on Lockwood, it looks as if it might have been a reasonably successful breeding season. Whether they will survive a GBBG colony is something we will find out.
High Maynard also held a roosting Red-Crested Pochard which I presumed was a female but it woke up long enough for Pete to see it was an eclipse male with a red bill. Otherwise just a few Common Sandpipers scattered around the reservoirs and the usual two Peregrines. Long sits/sleeps at likely warbler spots produced absolutely nowt.
*Oddly enough there was a dead adult GBBG on the side of No 4 by the anglers' hut and what looked to me to be another half-submerged dead bird at the bottom of the nesting island. I did see one adult fly off so the young birds are not orphans yet.
