Not sure if those two guys were trying to catch some shots of the hooded mergansers or the buffleheads in the pond. One thing was clear, none of them wanted to stay long enough for the photogs. The photogs went one way, the birds went the other. I was there just at the right time to take full advantage of the situations. Don't know if those two fellows got their shots though. I certainly got mine, unexpectedly.
Before I could settle down, the bufflehead just started its run and take off. So I had no choice but to pan and fire off a few Hail Mary shots. Sometimes I'm really amazed by the AF of the D300. They're not tack sharp but still I'm happy with the results considering the situations. These are full frame of two consecutive shots. Too bad about the hot spots though.
