No real chance of any birding this weekend due to various family commitments so here are two close ups of a male White-headed Duck (Oxyura leucocephala) taken during visits to a wildfowl collection.
[ F/8; 1/400; ISO 800 @ 250mm ]
The above image was taken at the end of November when the bill only just shows a hint of the major change that will take place as this male prepares for the breeding season when he sports a more colourful front end in the following March (see below).
[ F/11; 1/160; ISO 200 @ 300mm ]
I hope to get out tomorrow morning and see if anything new has turned up locally ... FAB.
