I visited Brighton Dam today, and the same scenario was playing out. 
I didn't realize what was happening until I saw mergansers pop up out 
of the water where an eagle had been swooping low a minute earlier. 
Then I noticed that the splashes that occurred when the eagle swooped 
low were mergansers diving.  The mergansers stuck around, though; the 
eagle didn't drive them off today.

As I was leaving today many Canada Geese came flying over, looking as 
though they were trying to decide whether to land.
