Anybody believe in coincidence? This morning I walked the river for a while. At one point an anhinga flew by high overhead, but I had my D800 with a 70-200 lens on it and I popped him. On my way back down the river I saw a cormorant fishing. When he saw me he took off. Again, he was pretty far away, but I popped him too.
Both of these pics are seriously cropped, but I'm posting them for instruction rather than criticism. Look at the anhinga's beak, and then the cormorant's beak. Since the anhinga has his neck pulled in and pretty straight it's hard to tell the difference between the necks on the two birds, but the beaks tell the tale.
