Last Friday evening, Dave James and I found a Black-necked Grebe on the main barrage lake at Clifford Hill Gravel Pits and it is still present there today. This appears to be the only one to have been recorded in the County so far this year. We can normally expect up to half a dozen records annually, with Scaldwell Bay at Pitsford Reservoir being the place to find one as, in recent years, it has consistently produced one or two from late August into September.
The solid black crown and intensively dark fore-neck suggest this one is an adult in moult to winter plumage. Compare this with the full summer plumaged adult at Pitsford last August. Thanks are due to Jonathan Philpot, who appears to have managed a much closer approach to obtain images than I have been able to!
