Domesticated Mallard ?
This ridiculous-looking, but clearly awesome, hybrid duck has lately become very close with our Egytian Goose.
I decided this morning that I had been spending too much time shooting arty black and white stuff, and it was time to put put my optically unsound 300mm f/4.5 and Komura 2x on my D40, slap it all on my monopod, and go shoot some waterfowl.
This highly satisfactory shot is one of the results. Unfortunately, even though it was noon, I had to shoot at ISO 1600 to keep my shutter speed up while stopped down far enough to maintain some sharpness with the telelconverter. I normally don't blink at bumping up the ISO, because I like grain; with bird plumage, it can be slightly more troublesome, because the fine details get obscured by the grain. Still, for a shot like this, a little grain is a price well worth paying.
Update: Someone who sounds highly knowledgeable ID'd this as a domesticated Mallard. I'll follow this up.
