It seems the word is out in the Black Skimmer world.
They have found the water is low, and fishing is easy.
I have been back out to more marshes since the first day I spotted Skimmers. We went to multiple marshlands, all had flocks of Black Skimmers, some in the hundreds.
Time to use larger memory cards. I am thankful for 10 shots a second, you need absolutely need it.
However, 1,000 shots per card (my limit) means I better have 3 sets of cards (we shoot 2 cards at the same time).
