Ryder's Mere - Black-throated Diver

The last time I was here, was to admire the reasonably long staaying Hoopoe and I remember checking out the patch of water (Ryders's Mere) adjacent to the marsh which looked 'interesting'. It was certainly of interest today, a diver had settled down overnight which was now considered to be a Black-throated Diver.

It was still there on arrival but apt to disappear after long distance dives (nothing new here then!)

The light was pretty dire on arrival but occasional close appearances eventually confirmed it was juvenile Black-throated Diver (there was quite a bit of discussion leading up this!) The white flanks being the most obvious distinguishing feature, with striking thight patch. Head shape was probably the most misleading feature for Great Northern confusion!









A hint of a chin strap - intriguing many!







The one and only wingflap.....






Head on shots...










The sun all too briefly threatened to come out....












The latter shots in good light show the disappearing chinstrap to be largely due to the neck aspect and light.....
