A Moroccan Red-knobbed Coot with strange red nodules on the forehead sprang to mind.
Disappointingly, later, upon close inspection of the images, the strangely shaped forehead appeared more of a growth like lump.
On the Red-knobbed Coot the bill apparently shows a greyish hue and the back is flatter.
Maybe, it had a brain tumour, hence it was on salt water instead of fresh!
So it would appear that once again the discovery of a mega rarity has proved a mere fleeting fantasy. I really should have learnt by now. The next telesales person to ring isn’t half going to feel the intensity of my frustration.
