I wasn’t expecting Mr. pT. (Great Blue Heron Pterodactyl) at the beginning of our walk. I had my ISO set at 400, which is a little slow against dark trees at sunset.  It’s one thing not to expect the Mr. pT., which I should know better, since I see him almost every night. But I really wasn’t expecting to see Ms pT., so imagine my surprise and excitement when Mr. pT. swooped down and flushed Ms pT. out of the clearwater ditch to do a pterodactyl tango on their way over the bosque to the rio Grande.  Part of the challenge is to see if you can find Mr. pT. against the tangle of bare cottonwood branches in the first six photos; and then see if you can find Mr. pT. and Ms pT. in the 7th photo and the last photo.
