Hi all,
For those that believe they may have seen the bird might I suggest reviewing 
the following excellent photographs of Baer's Pochard?

For males note the greenish tinged black head and neck. A rich dark-chestnut 
breast also sharply contrasts with a white belly and flanks. In breeding males 
the white appears to be so extensive that typically some white extends just far 
enough up the flanks to reach the edge of the closed wing. Note the barred 
appearance of the white on the flanks rather than a more uniform edge typical 
of Hardheads. Also note that the chestnut brown of the flanks is usually a 
shade or two lighter than that of the breast. This in combination with the 
white belly and lower flanks results in the breast being 'cut off' from the 
belly and flanks with a vertical line when the bird is on the water. Also note 
(as pointed out by Mike Carter) that males have a rather narrow pale blue grey 
tip or band to the bill (behind the black 'nail' at the bill tip). Hardheads 
typically show a much broader and more clearly defined blue-grey 'band' towards 
the bill tip.
Check out the following sites to see the bill of a Hardhead.

I hope this of some help.

And just repeating what Chris Lester said... we remain keen to see any 
photographs of the claimed bird.
